Answer :

In  this question the temperature is decreased by 400k from the initial temperature v1/t1=v2/t2 thus the volume of the ideal gas decreases by half.

The volume of a fixed mass of gas is linearly proportional to temperature at constant pressure. The volume of a fixed mass of a gas reduces when it is cooled and increases when the temperature is raised. The volume rises with rising temperature and falls with falling temperature.

All these relationship between volume, temperature and pressure is explained by formula pV=nRT  where p is pressure, V is volume and T is temperature.
