What temperature in degree centigrade would be necessary to double the volume of a gas (initially at STP), if the pressure is reduced to half ?

Initial conditions [S.T.P.] | Final conditions ---------|------------------ P 1 = Initial pressure of the gas = 1 atm | P 2 = Final pressure of the gas = 0.5 atm V 1 = Initial volume of the gas = V | V 2 = Final volume of the gas = 2V T 1 = Initial temperature of the gas = 273 K | T 2 = Final temperature of the gas = ? By Gas Law: Substituting the values : ∴ Final temperature of the gas = 273 K = 0 °C
