Heat is defined as energy in transit from a warmer body to a cooler body. In SI, its unit of measurement is the joule (J).
A simple definition of heat is the degree of warmth or hotness. *the earth science definition*- The average Kinetic energy of a substance. Kinetic energy is energy at motion. Potential energy is energy at rest.
This accounts for heat conducted directly through a building envelope. If heat transfer is outwards (warmer temp inside than outside), negative. If heat transfer is inwards (warmer temp outside than inside), then transmissibility is positive.
Rally scoring in volleyball is where a point is given after each play. Before rally scoring, only the serving team could score a point. With rally scoring, either team has a chance at the point. Rally scoring has two benefits: 1. Speeds up the play. Games could drag on and on if the serving team kep…t siding out. 2. Rewards good defense. Knowing that you have a chance to score even if you're not serving allows a team to be more aggressive (MORE)

Water contains two hydrogens and one oxygen atom. It is bent in the shape of an "L". The position of the hydrogen allows the hydrogen to interact with other highly electronegative atoms in other molecules. Oxygen is a highly electronegative atom. The hydrogen forms hydrogen bonds with other water mo…lecules' oxygen atom. This occurs throughout a solution of water. A tremendous amount of heat (energy) has to be applied to break these bonds for water to change from one state to another. This is why it has a high boiling point when you try to go from liquid to gas. (MORE)

Can an element that conducts heat is malleable and has a high melting point be classified as a metal?
You are in a slightly gray area. There are compounds that wouldmeet those criteria but wouldn't necessarily be a metal. A keycharacteristic of a metal is also to conduct electricity. There aretrue metals that have "low" melting points as well. ("low" being arelative term)
Point: (noun): the tapered, sharp end of an object; a dot or single location (verb): to direct attention to something, usually by using your finger to aim at it A spatial point is a location defined on two (or three) axes, having no actual size.
Glass windows provide passive solar heating for buildings. Sunlight passes through the glass and is absorbed by surfaces in the building. It is transferred into heat energy, which is emitted as infrared radiation. This is reflected back into the building by the glass.
Because the bond between the O atom and H atom is very polar and the shape of the molecule is in a bent configuration (think a Mickey Mouse hat from Disney World) this places the center of the partial positive charge between the two H atoms and the corresponding partial negative charge on the O atom… itself. Since these charges are not in the same place, water is said to be a polar substance. This means that the partial negative charge on the O will attract the partial positive charge from the H's from a different molecule of water. This attraction most be overcome in order to turn the liquid into a gas. This attraction is known as hydrogen bonding. (MORE)
A system can be defined as a network or set of things that create a whole. Systems are commonly referred to in relation to computers and other technological devices.
The answer is: it depends. Local codes in metro areas might restrict you from doing that, so its best to check with a building official in your area first.
Depends on how many fittings you will be using. If we're talking 1/2" - 1" and less than 20 fittings the volume will be changed neglagibly. If we're talking larger diameter pipe or lots of fittings you could see a noticible change in volume but not a lot. Unless the system has thousands of feet of p…ipe and hundreds of fittings then you would see a signigicant change. (MORE)

Thermodynamics deals with the equilibrium states of matter and can be extended to define the driving forces for changes from one equilibrium state to another when a system is subjected to external changes. When a system changes from one equilibrium state to another, thermodynamics also helps to dete…rmine the quantity of work & heat interactions according the the path taken to transition from the initial state to the final state. Heat is the movement of energy from one system to another due to a temperature gradient. It is frequently confused with "internal energy" or "thermal energy". We think of a system as being "hot" when it has a lot of internal energy that it can transfer to another system which is at a lower temperature. When the energy moves, it is called heat. As an analogy, we can compare heat to rain. When the water is in motion from the clouds to the ground, we call it rain. The rain moves due to a potential energy gradient between the clouds and the ground due to gravity. When the water is tied up in the clouds, it isn't rain. When it is pooling on the ground it isn't rain. It is only rain when it is moving between the two. Likewise heat is the energy MOVING from one system to another. You can heat a system up by transferring energy into it via heat - or you can add the energy to it via doing work on it. Once the energy is added, the internal energy has increased - but it doesn't have more "heat". (MORE)
When something feels hot it is in fact radiating long wave radiation. (Infra-red radiation) as to put a definition on heat I would say that heat is energy emitted by a source as infra-red. This is my first answer so I hope it was helpful :)
Hydronic heating makes the most sense in new construction where you will heat the entire house with the radiant floor heating system and have room for all the mechanical equipment and a source of fuel other than electricity.
A fundamental concept of thermodynamics is that heat will flow from where it is hot to where it is cool. Another way to say this is that heat moves from where it's hot to where it's not. This is always the case, and is the driving force behind the flow or movement of thermal energy. . Something th…at needs to be understood is that from a thermodynamic perspective, heat is only heat when the energy is in transit. By analogy, rain is only rain when it is falling. Before it falls, it is a cloud, after it lands, it is a puddle or a river or a lake etc. A hot object does not have "a lot of heat" nor is it correct to say that it is "high heat" - it has a lot of internal energy . Changes in the internal energy of an object are manifest as changes in temperature. Heat will flow between a high temperature and a low temperature so it could be said (informally - and incorrectly) that heat flows from "high heat' to "low heat" if you define high heat as high temperature and low heat as low temperature.

An air trap is where the air is bled out of a system normally,there is also trapped air in some poorly designed systems orsystems with water having recently been added.
H2O has high values for its specific heat and boiling point because it is made up of hydrogen bonds. Hydrogen bonds are the strongest type of intermolecular forces. Hydrogen bonds occur whenever hydrogen bonds with fluorine, oxygen, or nitrogen. Since they are the strongest type of bonds, it takes m…uch more energy to break apart the molecules, which is what needs to happen for something to boil. (MORE)
True hydronic baseboard heat has an opening at both the top and the bottom of the wall unit with a finned copper tube running down its length. Because hot air is less dense than cold air, the hot air naturally rises. As heat is absorbed in the air surrounding the finned copper tube, it rises and flo…ws out of the opening at the top. (convection) As this warm air leaves the heater it draws cooler air into the bottom opening which is then heated and flows out the top continuously as long as there is heat in the finned copper tube.

Latent means hidden. Let us imagine that we have placed a container with water on a stove. A thermometer is inserted to note down the temperature now and then. As heat is handed over to the water in the container, its temperature rises. Say initially the temperature was 20 deg celcius. Now the tempe…rature would go through 30, 40, 50, 60, 70, 80, 90, 95, 97, 98, 98.5, 98.9 and 100 deg. After 100 is reached though heat is continuously supplied, there won't be any rise thereafter. Now the question arises. Where does the heat go? The heat given is utilized not to rise the temperature but to covert each gram of water into vapour ie steam. Hence this heat is hidden and not sensed by the thermometer. So it is named as Latent heat of vapourisation. Same way if we supply heat to an ice block with temperature -5 deg celcius, the temperature initially rises through -4, -3, -2, -1, -0.3, 0 deg celcius. After it reaches 0 deg, the temperature will be there itself. But heat is continuously given to the ice block. But no temperature rise. Here too the heat given is hidden and is used to melt every kilo gram of ice into water. Hence change of state. So Latent heat of melting or fusion of ice. (MORE)
A heat conductor is a material that readily transports heat from one location to another through the process of conduction. Some materials with high melting points are actually good insulators and very poor heat conductors, whole some materials with low melting points may be good conductors.

"On point" is to be "on the point" of doing something, which is usually well understood. People will often explain something to another to make them understand a particular situation or thing, and they will respond by saying "get the point?" Also, In military parlance, to "be on point" is to assume …the most exposed position in leading an army into battle or attack, which means being the front man. Furthermore, on point can refer to "On-Point", a radio talk show hosted by Tom Ashbrook. (MORE)
There are a few different companies that offer hydronic heating systems. The prices of these systems will vary depending on the system one chooses to purchase. Some companies that produce these heating systems are Greenheat and Ascot.
Latent heat is the amount of energy that is needed to change the state of matter. Either from a solid to a liquid, from a liquid to gas or vice versa. For example if you boil a kettle of water, energy or latent heat is added to the water from the element within the kettle. The water will heat up and… eventually turn to steam. (MORE)
