Question

The behaviour of the real gas approaches that of an ideal gas is when:
(correct answer +1, wrong answer -0.25)

• A. Temperature is high and the pressure is low
• B. Pressure is high and the temperature is low
• C. Volume is low and pressure is high
• D. Temperature is low and volume is low

Answer 1

The correct option is A Temperature is high and the pressure is low

For a gas to behave ideally, the molecules must be far apart and there should be no force of attraction. At high temperature and low pressure, the molecules are far apart and they do not have any force of attraction and hence they behave ideally.
