According to the ideal gas law, PV = nRT, where P is the pressure, V is the volume, n is the number of moles, R is the gas constant, and T is the temperature.

Pressure (P): If the temperature is increased while keeping the volume constant, the pressure will increase according to the ideal gas law. Therefore, the pressure will double in this case.

Volume (V): If the temperature is increased while keeping the pressure constant, the volume will also increase according to the ideal gas law. Therefore, the volume will double in this case.

Moles (n): The number of moles does not change when the temperature is increased, as it is independent of temperature. Therefore, the number of moles stays constant.

Gas constant (R): The gas constant is a constant value, and it does not change with temperature or any other variable. Therefore, the gas constant stays constant.

Temperature (T): The temperature is increased from 200 K to 400 K. Therefore, the temperature doubles in this case.
