Question

Write a note on change in state of matter with respect to change in temperature and pressure at standard atmospheric condition

Answer 1

Physical conditions like temperature and pressure affect state of matter. ... 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)

Answer 2

Explanation:

change in temperature:

solid (heat)------> liquid (heat)------> gas (cooled)------> liquid (cooled)-----> solid

change in pressure

gas (increased pressure)------> liquid (increased pressure)------> solid (decreased pressure) -----> liquid (decreased pressure)-----> gas
