Question

Under which conditions do you expect helium gas to deviate most from ideal behavior?. . a. 100 K and 1 atm. b. 300 K and 2 atm. c. 100 K and 5 atm.

Answer 1

Ideal behavior is approached by gases when the conditions of the system are at a low pressure and high temperatures. Therefore, the correct answer is C. At the conditions of lowest temperature highest pressure, gases will deviate from an ideal gas.
