Heat And Thermodynamics - Figure B
... Heat is a form of energy which appears when two bodies at different temperature are placed into thermal contact. It can flow from high temperature to low temperature till temperature of the two bodies becomes same. Thus, we can say that heat is the energy in transit. Heat is not property of system, ...

... The specific heat depends on pressure. We will only discuss it at atmospheric pressure. The specific heat is very different for different materials. Water has a very high specific heat of 4186 J/(kg ℃). This means that water can carry much energy without a big increase of its temperature. Thus, wate ...
