In the figure, a container is shown to have a movable (without friction) piston on top. The container and the piston are all made of perfectly insulated material allowing no heat transfer between outside and inside the container. The container is divided into two compartments by a rigid partition made of a thermally conducting material that allows slow transfer of heat. The lower compartment of the container is filled with 2 moles of an ideal monoatomic gas at 700K and the upper compartment is filled with 2 moles of an ideal diatomic gas at 400K. The heat capacities per mole of an ideal monoatomic gas are C_V=3/2R, C_P=5/2R, and those for an ideal diatomic gas are C_V=5/2R, C_P=7/2R, Consider the partition to be rigidly fixed so that it does not move. When equilibrium is achieved, the final temperature of the gasses will be

An amusement park ride consist of a large verticle cylinder that spins about its axis first fast enough that any person inside is held up againest the wall when the is mu_(s) and the radius of the cylider is R a. Shown that maximum period of revolation neccessary to keep the person from falling is T = (4 pi^(2) mu_(s) R //g)^(1//2) b. Obtain a numerical value for T taking R = 4.00m and mu_(s) = 0.400 . How many revolations per minute does the cylinder make? c. If the rate of revolation of the cylinder is make to be some what larger what happens to the magnitude of each one of the forces acting on the person ? What happens to the motion of the person ? d. If instead the cylinder rate revolution is made to be somewhat smaller what happens to the magnitude and what happens to the motion of the person ?

An ordinary refrigerator is thermally equivalent to a box of corkboard 90 mm thick and 5.6 m^2 in inner surface area. When the door is closed, the inside wall is kept, on the average, 22.2^@C below the temperature of the outside wall. If the motor of the refrigerator runs 15% of the time while the door is closed, at what rate must heat be taken from the interior whicle the motor is running? The thermal conductivity of corkboard is k=0.05 W//mK .

A 0.60 kg sample of water and a sample of ice are placed in two compartmetnts A and B separated by a conducting wall, in a thermally insulated container.
