Argon gas of mass 5 g is contained within a cylinder with a movable piston at a temperature of 23°C and an atmospheric pressure of 1.01 x 10° Pa. The molar mass of argon is 40 g mol- An electrical heater was used to heat the gas inside the cylinder for 12 s. The gas expanded, and its temperature was increased by 23 K. Assume that there was no loss of heat to the environment, and the pressure did not change during heating. After heating, the volume of the gas changed by O 33 x 10-4m3 O 2.4 x 10-4m3 O 3.8 x 10-4m3 O 52 x 10-4m3 The power of the electric heater used to heat the gas is: O 1.0 W O 1.6 W O 3.0 W O5.0 W
