A gas having a viscosity of 2.04 x10° kg/ms, the thermal conductivity of 0.0293 W/m °C, undergoes an isobaric non-flow heating process at a pressure of „P“ (= 95 × Reg. No.) kPa and temperature changes from 22 °C to „T“ (= 25 + Reg. No.) °C. The specific heat of the fluid is dependent on temperature and is given as C, = 1.44+82/(T+48); where T is in Celcius. During this process, its volume changes from 0.28 m/kg to 0.658 m³/kg.
