When does a gas deviate the most from its ideal behavior ?

AAt low pressure and high temperature
BAt high pressure and high temperature
CAt low pressure and low temperature
DAt high pressure and low temperature
Correct Answer

Solution

At high pressure and low temperature, a gas deviates the most from its ideal behaviour.

Under these conditions, the gas molecules are close to each other and they exert significant intermolecular forces on each other.

Also, the volume of gas molecules becomes a significant portion of total volume and cannot be neglected.

Hence, the correct option is D.
