23. A gas will approach ideal behaviour at

$(1999,2 M)$

(a) low temperature and low pressure

(b) low temperature and high pressure

(c) high temperature and low pressure

(d) high temperature and high pressure

Show Answer

Answer:

Correct Answer: 23. (c)

Solution:

At high temperature and low pressure, the gas volume is infinitely large and both intermolecular force as well as molecular volume can be ignored. Under this condition postulates of kinetic theory applies appropriately and gas approaches ideal behaviour.
