How can we know heat is coming from an object if we are not touching the object?
AshnaHasan
Gravity as well as electrostatic and magnetic attraction and repulsion provide real life examples of forces being exerted by one object on another without them being in contact with each other. Many children are aware of magnetism and have played with fridge magnets. They may also have played with picking up small pieces of paper or other objects with a comb charged by rubbing against the sleeve of a jumper or by pulling through hair. They will also be aware that things fall towards the Earth. However, they are unlikely to think about these experiences as involving forces, i.e. pushes and pulls.
It is common for students to think that all metals are attracted by magnets, and that the size of magnets determines their strength.

How do you know how hot an object is?
Heat is a form of energy. The energy is tied to the molecules of the object. The faster the molecules in an object vibrate, the more heat energy it contains and therefore the more hotter it is. By measuring the amount of vibration in an objects molecules, you can calculate how hot it is.
What happens when Heat energy moving from one place to another due to temperature differences?
Molecules in warmer object will have more average kinetic energy of molecules compared to the molecules in cooler object. Therefore the energy will be transferred from the region of more to kinetic energy to a region of low kinetic energy of molecules until equilibrium is reached between both the objects. This is similar to the process of diffusion which dictates the flow of solute molecules from an area of its high concentration to an area of its low concentration.
Why is important to know the density of an object?
so you know how much an object is denser compared to another object.
What happens to heat that enters an object?
I'm not 100% sure about this though.heat is some kind of radiation right.. when heat radiation contact an object,the molecules on the surface of the object start vibrating in a specific way.so when those molecules start to collide on each other,a chain reaction occur as long as the source remains or found a new one. let me know if this isn't right.. :)
Why does a blue object only reflect blue light?
all of the colors of the rainbow are coming down to the object and all of the colors get absorbed except blue, it gets reflected. I am sorry i really dont know the answer but i hope this helps a little bit.
How do you know if a train is coming?
Put you hand on the rail and if you feel heat, then it coming.
Do you know why there is no heat coming from the heater on a 1998 buick lesabre?
no
Do your other female dogs know if one of your females is coming into heat?
Yes
How do we know that the transfer of heat occurred between two object?
The one that is cooler will become warmer.
What does the brain do for your body?
The brain is the center of nerves. It sends shocks to your body letting you know that you are either in danger or something as simple as touching another object.
Why is your heat coming just out of your defroster?
What type of auto is this? I may be able to help. Let me know.

How can charges be transferred between to objects?
1.) by touching a positive object onto a negative or neutraul which will turn the object into having a negetive charge also 2.).......? 3.).......... edit if u know other 2
How is thermal energy transfered when particles are touching?
I think they create friction and that creates heat. I don't really know though, that was just a guess.
How do you know that a burning of candle wax is an exothermic change?
Because heat is coming out of the reaction, that means it is losing energy
How can the specific heat of water be used to determine the specific heat of an object?
If you know the temperature and mass of an object, and the temperature, mass, and specific heat of the water, if you dunk the object in the water, and measure the temperature of the water and the object (once the object and water have the same temperature), using reasoning skills and/or equations you can figure out the specific heat of the object. Historically the specific heat was related to SH of water . Water being 1 That now is seen as archaic. The specific heat (of a substance) is the amount of heat per unit mass required to raise the temperature by one degree Celsius. This does not apply if a phase change is encountered. Every substance has to be measured separately .
Let's say there are two objects Object 1 has a high specific heat and Object 2 has a low specific heat Which object would heat more I'll give trust point and recommend contributor?
Heat energy (gained/lost)= mass x specific heat capacity x temperature(rise/fall) Now with this expression we come to know that for a given mass and with a given amount of heat energy in joule, as sp. heat cap is more then rise / fall in temperature will be less and vice versa.
