Question

How does second law of thermo dynamics explain expansion of gas?​

Answer 1

Answer:

hope it useful means mark as brainlist please.

Explanation:

The Second Law of Thermodynamics(first expression): Heat transfer occurs spontaneously from higher- to lower-temperature bodies but never spontaneously in the reverse direction.

The law states that it is impossible for any process to have as its sole result heat transfer from a cooler to a hotter object. We will express the law in other terms later on, most importantly in terms of entropy.
