Question

2 kilograms of gas with a molecular weight of 28 is closed and equipped with an electrical resistor. located in a rigid tank. This system has a fixed resistance of 10 amps and a voltage of 12 volts for 10 minutes. is implemented. When thermal equilibrium is reached, it measures that the temperature of the gas rises by 40.3°C. shows. It is estimated that the heat transfer to the environment occurs as 20 W. With the help of the measured data and assuming the ideal gas behavior, the gas's Determine the average value of the specific heat Cp in kJ/(kg K).
