Question

Under which conditions of temperature and pressure would a sample of H2(g) behave most like an ideal gas?

(1) 0°C and 100 kPa
(2) 0°C and 300 kPa
(3) 150°C and 100 kPa
(4) 150°C and 300 kPa

Answer 1

3). 150°C and 100 kPa


Gases behave ideally at high temperatures and low pressures (less intermolecular forces)
