Entropy and Pressure

Postby Ami_Pant_4G » Sat Feb 08, 2020 9:41 pm

When pressure increases, does entropy decrease? If so can someone please explain why? Thanks in advance.

I think that when pressure increases, volume decreases and when volume decreases entropy also decreases.

Yes! When pressure increases, entropy decreases because volume decreases.

Entropy increases as a system gets bigger, meaning that the opposite is also true (a smaller volume means entropy decreases). When we are talking about pressure and temperature we are usually talking about a closed system with a piston, so if a piston compresses and increases pressure, volume is decreased and entropy is therefore also decreased
