Question

Please help!!!

Answer 1

Answer : The correct option is, (e) at high temperature and low pressure

Explanation :

The conditions for ideal gas are :

Ideal gas are those gas that has no intermolecular attractions.

Ideal gas are those gas that have negligible volume.

The ideal gas equation is,

$PV=nRT$

The conditions for real gas are :

Real gas are those gas that have intermolecular attractions.

Real gas are those gas that have volume.

The real gas equation is,

$(P+\frac{an^2}{V^2})(V-nb)=nRT$

A real gas behave ideally at high temperature and low pressure condition.  Or we can say that most of the gases behave ideally at high temperature and low pressure condition.

Hence, at high temperature and low pressure the most of the gases behave as an ideal gas.

Answer 2

I believe the answer is E. They behave ideally at high temperature and low pressure.
Hope this helps.
