Problem 1. Each of two vessels of equal volume initially contain 1 g of ideal gas each. One vessel is kept at temperature T1 = 300 K, the other at T2 = 400 K. The vessels are then connected by a thin tube. Find the mass of gas in each vessel when the system reaches the state of mechanical equilibrium. (Assume that once any amount of gas moves from one vessel to the other vessel, the moved gas quickly reaches the temperature of the destination vessel.)

A mass of at a temperature of 40 degrees Celsius and pressure of 2 bar is trapped in a cylinder behind a leak-proof piston. The temperature of the gas is to be increased to 65 degrees celsius while its pressure is to be decreased to 1.25 bar. Describe how this change of state could be brought about in a quasi-equilibrium manner. You may make use of any external devices required and also make any assumptions about the walls of the cylinders.
Plot the process on pv diagram which show the state points relative to the vapor dome. Label the states 1,2,3.. to indicate the sequence of the change in state.
Two spheres each 3.0ft in diameter are connected by a pipe in which there is a valve. Each sphere contains nitrogen gas with sphere A has a temperature of 80°F, while the other is 120°F. With the valve closed, sphere A has a gauze pressure of 51.9 psi and the other 10.9 psi. After the valve has been open long enough for equilibrium to obtain, what is the equilibrium temperature if the final pressure is 35.2 psig?

Problem 3: A large room contains a volume of air of Va = 11 m3 at a temperature of Ta = 55° F. It also contains a bathtub holding a volume of water of Vw = 0.51 m3 at a temperature of Tw = 111° F. Part (a) If the density of the air at Ta is ρa = 1.25 kg/m3, calculate the mass of air in the room in kilograms. Part (b) If the density of the water at Tw is ρw = 1000 kg/m3, calculate the mass of the water in the bathtub in kilograms. Part (c) Take the room and water as an isolated system. Write an equation for the equilibrium temperature of the system T in terms of ma, Ta, mw, Tw, and the specific heat capacity of the air ca and the water cw. Part (d) Calculate the final temperature of the system in kelvin, assuming a constant specific heat for the water of cw = 4180 J/kg⋅K and a constant specific heat capacity for the air of ca = 1010 J/kg⋅K. Part (e) Calculate the change in the internal energy ΔU of the room-water system in joules.

A closed system is comprised of 10kg of pure water substance initially at a temperature of 400 C and a pressure of 8.5 MPa (state 1) 1. For state 1, show the system is in the superheated vapour phase 2. Evaluate the specific volume of the steam in state 1 using the thermodynamic property tables and compare it to the value obtained assuming the steam behaves as an ideal gas. Which value would you have most confidence in (give reasons for your choice) The system now undergoes an isentropic (constant entropy) adiabatic process on which its pressure drops to 100 kPa (state 2). For steam the specific gas constant = 461.5 J/kgK Use the attached table of properties
There is a calorimeter composed of a thermally insulated container. Inside it are 1.2 kg of ice at −15 ∘C. How much mass of water at 60 ∘C needs to be added in the calorimeter for the final temperature to be 5 ∘C? If water vapor were introduced at 100 ∘C instead of water, how much mass of steam would have to be added for the final temperature to be 30 ∘C? What volume would the water vapor in the previous part occupy (before adding it to the calorimeter) if the pressure at which it is contained is 1.20 × 105 Pa? NOTE: The molar mass of water is 18 g / mol. ice = 2090 J / kg ∘C. water = 4180 J / kg ∘C. Lf, water = 3.33 × 105 J / kg. Lv, water = 2.26 × 106 J / kg
