Does heat transfer from objects with high temperature to objects to low temperature?
An object with a higher temperature will have a higher amount of thermal (heat) energy. The difference in amounts of thermal energy between a warmer and cooler object can be thought of as the difference in height of 2 coulmns or pillars of marbles.
If you were to place a ramp across the 2 pillars and placed a marble on it then it would roll down toward the lower pillar. In the same way, heat energy is transferred from the hooter object to the cooler one.
However as the heat energy goes from the hotter to the cooler, the temperature difference gets less (as more heat energy means hotter temperature). So the 2 objects will get closer and closer to the same temperature until they are both the same (we say they are in equilibrium).
Going back to our pillar analogy, as more 'marbles' roll from the higher pillar to the lower pillar, the one gets shorter as the other gets taller in height until they are exactly the same height where the 'ramp' is flat and a marble would not roll in any direction.
It might be important to note that this 'ramp' is known as a gradient, and that in nature, things will always wish to balance out if they can.
Temperature is a measure of the heat energy of objects, and heat is the energy transferred from a high temperature location to a low temperature location. When two objects are in contact, heat always flows from the warmer object to the cooler object by conduction, until thermal equilibrium is established and the heat transfer stops (becomes the same in either direction). The transfer of heat continues as long as there is a difference in temperature…
Specific heat capacity is the amount of energy or heat required to raise the temperature of a unit mass of a substance by one kelvin. So if the specific heat capacity is high then you would require more energy or heat to raise its temperature. The specific heat capacity does not really have anything to do with how much you can increase an objects temperature. IT HAS TO DO WITH THE ENERGY NEEDED TO INCREASE…
We have discussed heat transfer and defined it to be the movement of heat. Heat can be transferred from one object to another, like the steak transferring heat to the plate, or heat can be transferred through an object, such as the baking a potato example. But, what is heat? We know we can feel heat. We can say it is a hot day, or the stove is hot, but that doesn't explain what heat…
In terms of differences in temperature what direction does heat flow between objects in thermal contact?
The heat will flow from the body with high temperature to the body with low temperature...the body of higher temperature loses the heat starts to become cold..and the body of lowest temperature gains the heat and starts to become hot..in this process when the temperature of both bodies reach in same temperature the two bodies will be in thermal equillibium condition..
What is the name of thermal energy that moves from high tepmerature objects to low trmperature objects?
The first law of thermodynamic show that heat transfer is equal to work.But he does not give the direction as that system is consuming work or doing work. Whereas the second law of thermodynamic give the direction as (1) Heat can flow naturally from high temperature to low temperature.When heat is flowing from high temperature to low temperature he can produce work.(2)Heat can not flow naturally from low temperature to high temperature.for flowing heat from…
The principle behind this is called heat transfer. Heat transfer says that heat (or thermal energy) always transfers from high energy objects(hot) to a low energy objects(cold). If you touch a stove, what you feel is a large amount of thermal energy being transferred into you through your contact with the stove. The hotter the object, the more thermal energy will be transferred into you. The skin can only handle so much thermal energy, so…
It's caused by the difference in heat conductivity of the materials which those objects are made of.Marble for instance has a high heat conductivity. It's the same temperature as everything else in the room, but it moves heat away from your skin more effectively. As a result, marble feels colder than wood, which has a much lower heat conductivity.
a transfer of energy causing particles to create friction which then causes heat *the earth science definition*- The average Kinetic energy of a substance. Kinetic energy is energy at motion. Potential energy is energy at rest. Answer Heat is energy in transit from a body at a higher temperature to a body at a lower temperature. The definition of heat is the quality of being hot as a result of the high temperature.
A lot of materials are known for their relatively high thermal conductivities including: Silver Copper Gold Aluminum Brass (at least most types are pretty good conductors) Diamond Carbon nanotubes (along the tube) Graphite (along the plane - not so good between planes) Graphene (a 2-dimensional atomic-scale, honey-comb lattice in which one atom forms each vertex - sort of an ideal version of a single sheet of graphite) Water is also pretty good at heat transfer…
What type of heat transfer is responsible for making you feel cold when you are swimming in a pool that is cold throughout?
How is the solar chromosphere and corona heated to their high temperatures A Prominences and flares erupt from the photosphere out to the chromosphere and corona?
Why does the 2nd law of thermodynamics relate to the direction of heat flow and efficiency of heat engines?
Because Energy flow is from a high energy state to a low energy state the direction of flow of heat is from a high temperature to a low temperature. Because the second law states that no system can perfectly maintain it's total energy, the efficiency of a heat engine must necessarily be reduced by the entropy of the energy transfer.
this is simple as it see look when a body sweat there is moisture on surface of skin and when this moisture evaporate then ther eis transfer of heat from high temperature to low temperature that's why we feel cool after sweating ..... It needs heat to convert moisture to a vapour and this heat is supplied by the body via the skin. The loss of heat is felt as cooling.
Materials with a high specific heat can absorb a lot of energy and show little change in temperature?
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 that needs to be understood is that from a thermodynamic perspective, heat is only heat when the energy is…
Heat is normally transferred to specific areas by means of a 'heat sink' which is usually made of a material with low resistance and high transfer of heat. An example of this can be seen in most computers, the heat sink collects the heat from the processor, and there is (usually) a fan which is near or on the heatsink to remove it from the heat sink, effectively lowering the temperature of the processor.
