Answer : The correct option is, (4) increased temperature and decreased pressure
Explanation :
The ideal gas conditions are :
These are those gas that has no intermolecular attractions.
These are those gas that have negligible volume.
The ideal gas equation is,
The real gas conditions are :
These are those gas that have intermolecular attractions.
These are those gas that have volume.
The real gas equation is,
As we know that a real gas behave ideally at high temperature and low pressure condition.
Hence, the correct option is, (4) increased temperature and decreased pressure
