Question

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

• A. $0^{\circ }C$ and $0.001atm$
• B. ${100}^{\circ }C$ and $2.0atm$
• C. $-{13}^{\circ }C$ and $1.0atm$
• D. $-{13}^{\circ }C$ and $200atm$

Answer 1

The correct option is D $-{13}^{\circ }C$ and $200atm$

Generally 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.
