A cubic tank 1m3 is filled with air at 280k and 100 kpa. It is fitted with a relief valve that will vent at 600 kPa. Heat is added until the gas reaches the limiting pressure.
Determine the air temperature at the limiting pressure, Assuming specific heat varies determine the change in internal energy during the process. Determine the internal energy during the process if we use a constant specific heat. ex 300k and calculate the heat transfer to the system using the variable specific heat and the constant heat.
