Argon initially at -77 °C and 9720 kPa is contained in 1.2 m3 rigid tank. The tank is heated until the temperature in the tank rises to 0 °C. Using the generalized charts, the entropy departure factor at the initial state is equal to 0.3 0.8 0.9 0.5

A 50kg copper block initially at 180 degrees C is dropped into an isolated tank containing 90 L of water at 15 degrees C. Determine the final equilibrium temperature and the total entropy change for the process.

Dont copy from others and answer should match. A large kitchen pot initially contains 5 kg of water at 25°C. A burner is turned on and heat is added to the water at a rate of 500 cal/sec. Determine how many minutes it will take for one-half of the mass to evaporate at standard atmospheric pressure.
