Question

Which of the given sets of temperature and pressure will cause a gas to exhibit the greatest deviation from ideal gas behavior

• A. 100${}^{\circ }$ C and 4 atm
• B. 100${}^{\circ }$ C and 2 atm
• C. -100${}^{\circ }$ C and 4 atm
• D. 0${}^{\circ }$ C and 2 atm

Answer 1

The correct option is C

-100${}^{\circ }$ C and 4 atm

Gas deviate from ideal gas behaviour to real gas (according to Vander Waal's at low temperature and high pressure)
