Question

5. At constant temperature, increase in pressure causes melting of ice with greater ease-why?​

Answer 1

${\huge{\bold{\underline{☯︎Answer✍︎}}}}$

This is the basis of pressure cookers, superheat steam engines, etc. On the other hand, ice has a lower molar volume than water (it floats), so increasing pressure leads to a freezing point decrease. Higher temperature will make the molecules jitter more and they tend to separate, melt at sufficiently high temperature.

Answer 2

Answer:

Please mark as Brainliest!!!

Explanation:

Water has an unusual phase diagram: its melting point decreases with increasing pressure because ice is less dense than liquid water. The phase diagram of carbon dioxide shows that liquid carbon dioxide cannot exist at atmospheric pressure. Consequently, solid carbon dioxide sublimes directly to a gas.
