Are there any solids that do not change state after heating or change in pressure
Is it possible that an object of any state of matter does not change its state of matter no matter how much we heat, freeze or apply pressure on it?
A number of forces acting on a body do not cause any change in its state of rest or of uniform motion. The forces are:
(a) What do you understand by the change of phase of a substance?
(b) Is there any change in temperature during the change of phase?
(c) Does the substance absorb or liberate any heat energy during the change of phase?
