Question

why are gas laws not obeyed at low temperature and high pressure?​

Answer 1

Answer:

At low temperatures and high pressure, the inter-molecular interactions of the gases become significant, as molecules are brought closer. Also, the volume of the gases takes a finite value as they are compressed under high pressure and low temperature. Thus, the gas doesn't behaves ideally anymore, infact it starts behaving more like a liquid. Therefore, the gas laws become invalid at low temp. and high pressure.
