Under standard conditions heat will cause the phase of matter to change.
For instance:
Ambient air is much warmer (more heat) than an ice cube. If the ice cube is allowed to remain in contact with this air it will absorb some of the heat. As the ice cube heats up it melts into liquid water.
Two phase changes that occur when matter loses heat energy are: Solid to liquid: When a substance loses heat energy, it can transition from a solid phase to a liquid phase. This process is called melting. Liquid to gas: Another phase change that can occur when matter loses heat energy is the transition from a liquid phase to a gas phase. This process is known as vaporization or boiling.
When heat is added to a pure phase of matter, the kinetic energy of the particles in that phase increases. This increase in kinetic energy causes the particles to move faster and the temperature of the phase to rise.
Heat is needed for matter to change form eg: Melting, condensation, etc.
That will not happen unless matter is undergoing a phase change and the temperature you are measuring is that of the matter undergoing the phase change.
The solid phase of matter does not conduct heat well compared to liquid and gas phases. In solids, heat is transmitted through the vibration and collisions of atoms and molecules, which are more tightly packed and have limited freedom of movement, resulting in slower heat transfer.

No, phase changes in matter are not permanent. They can be reversed by providing or removing energy (such as heat) to the substance. For example, ice can melt into water when heat is applied, and the water can freeze back into ice when it is cooled.
Heat causes matter to become warmer, usually to expand,and occasionally to change its physical state.
Any type of reaction, really. You could add heat or remove heat (thermal energy) to cause the matter to change phase. Also pressure can compress the matter into a new form.
Wood, Plastic, Fabric... and a bunch of other stuff.
I am pretty sure that it is the temperature which is applied to the substance. For example when heat is applied to a solid it melts, causing it to change from one phase to another. Also when a liquid freezes the temperature drops and it converts into a solid.
