Heat increase molecular vibration in solid and to the certain point, the molecule would overcome the attractive force and change the state to liquid or gas depending on the surrounding pressure.
it changes its form, size, shape and chemical and physical changes occur.
The effect of heat on anything (gas, solid or liquid) is the same. Heat is energy and the application of energy to a system will increase the motion of the molecules in that system.
the effect of heat on liquid , solid and gases
If you look at the atomic structure of a solid, the molecules are held quite tightly with strong forces that prevent the solid from moving about. When you heat a solid such as chocolate, you are breaking these strong bonds and allowing the molecules to move about more freely. So, the more heat you put in, the more chocolate will dissolve.
Water have a very high heat capacity and that mean water can contain a lot of heat which resulted in the cooling effect. Remember ice is water in solid form.
If the solid is made of ice, then it will melt. But if you have enough heat, you can make the solid item melt.
heat doesnt travel from a solid to a liquid. a solid is heated up and turned into a liquid.
a solid melts (and the liquid remains at the temperature of the solid).
Conduction
It melts into a solid.
When this happens,the liquid loses all its heat & becomes solid.
What effect of moist heat sugar
Sublimation is an endothermic physical change (heat is needed).
