A volume of gas is confined to a cylinder with a freely moveable piston at one end. If you reduce the temperature in Kelvin by half,
(a) The pressure will reduce in half but the volume will double.
(b) The pressure will reduce in half as well as the volume.
(c) The pressure will reduce in half but the volume will remain the same.
(d) The pressure will remain the same but the volume will double.
