Hydrogen gas at 65 kPa, 200 °C is heated in a closed, rigid vessel until it reaches to 400 °C. Determine the amount of heat required for 0.5 kg of this gas, taking ?? = 14.209 kJ/kg-K, ?? = 10.085 kJ/kg-K.

QUESTION 4 Consider a 5 ft rigid container that is filled with 0.5 Ibm of helium. The initial pressure of the container is 60 psi. The container is then heated until the pressure reaches 110 psi. Determine the change in temperature, in °C, due to this heating process.

As shown in the figure below, a cylinder fitted with a piston is filled with 600 lb of saturated liquid ammonia at 45°F. The piston weighs 1 ton and has a diameter of 2.5 ft. * Your answer is incorrect. V= What is the volume occupied by the ammonia, in ft3? Ignoring friction, determine the force required, in lbf, by mechanical attachments, such as stops, to hold the piston in place. What is the volume occupied by the ammonia, in ft³? i 15376500 Patm = 1 atm Piston ft3 Ammonia Saturated liquid - Weight = 1 ton D=2.5 ft

A 2.8 m^3 rigid tank is filled with saturated liquid vapor mixture of water at 300C. If 2% of its volume is liquid and the rest is vapor, the total mass in the tank in kg is?
