give for substances which can change its state of matter by pressure, also explain it how!
Answers
Answer:
(a) The process of change of a substance from solid state into its liquid state on absorption of heat at a particular temperature is called melting/fusion and the temperature at which it happens is called the melting point.
Answer:
When thermal energy is added to a substance, its temperature increases, which can change its state from solid to liquid (melting), liquid to gas (vaporization), or solid to gas (sublimation). ... Decreasing pressure can cause it to vaporize. For some types of rock, decreasing pressure can also cause them to melt.
Explanation:
Changes in presure have very little effect on the volume of a liquid. Liquids are relatively incompressible because any increase in pressure can only slightly reduce the distance between the closely packed molecules. If the pressure above a liquid is increased sufficiently, the liquid forms a solid.
