Two moles of an ideal monoatomic gas are contained in a vertical cylinder of cross sectional area A as shown in the figure. The piston is frictionless and has a mass m. At a certain instant a heater starts supplying heat to the gas at a constant rate q J/s. Find the steady velocity of the piston under isobaric condition. All the boundaries are thermally insulated.

A gas thermometer is used as a standard thermometer for measurement of temperature. When the gas container of the thermometer is immersed in water at its triple point 273.16K, the pressure in the gas thermometer reads 3.0 x 10^4 N/m^2. When the gas container of the same thermometer is immersed in another system, the gas pressure reads 3.5 x 10^4 N/m^2. The temperature of this system is therefore
