The temperature must remain constant.

This is the Gay-Lussac law: at constant volume of a gas the temperature increase when the pressure increase.
As per Charles' law pressure increases as temperature increases provided volume is kept constant
Its kept in a museum in Paris, inside a glass case with the temperature inside the case kept the constant.
PV=nRt. If P is constant, get the value of V and solve for t.
You use a thermometer, to measure the temperature. As a guide to know how much heat to apply, the temperature reading must be kept within a certain range, to be constant.
All metals expand when heated and contract when cooled. It is important, therefore, that the standard metre is kept at some constant temperature. That constant temperature could be any temperature but the triple point of water is a convenient benchmark.

The pressure goes up.
The temperature factor increases to 1.1547, approx.
3.5 litre if pressure is kept constant.
