Question

Under which conditions of temperature and
pressure does a real gas behave most like an
ideal gas?
(1) 37 K and 1 atm (3) 347 K and 1 atm
(2) 37 K and 8 atm (4) 347 K and 8 atm

Answer 1

Real gases deviate from the ideal gas law under instances of high pressure and low temperature when the molecules are close enough for IMFs to take over so the answer is 3 

Answer 2

(3) 347 K and 1 atm is the correct one because a real gas behaves most like an ideal gas at high temperature and low pressure.
