Question

# For a gas, deviation from ideal behaviour is maximum at:

A
0C and 0.001 atm
B
100C and 2.0 atm
C
13C and 1.0 atm
D
13C and 200 atm

Solution

## The correct option is D −13∘C and 200 atmGenerally a gas behaves like an ideal gas at high temperatures and low pressures. So a gas will deviate most from the ideal behaviour in just the opposite conditions i.e. at a high pressure and a low temperature. So option (d) is the correct answer.
