Question (2)

QN0035803

When do real gases approach the ideal gas behaviour?

(A)
At low pressure and low temperature
(B)
At low pressure and high temperature
(C)
At high pressure and high temperature
(D)
At high pressure and low temperature

Correct Answer: B

Explanation:

At low pressure and high temperature the molecules are far apart and molecular interactions are negligible. Without interactions the gas behaves like an ideal one.
