A mixture of xenon and oxygen gas is compressed from a volume of 87.0 L to a volume of 81.0 L, while the pressure is held constant at 84.0 atm. Calculate the work done on the gas mixture. Be sure your answer has the correct sign (positive or negative) and the correct number of significant digits. KJ x10 X

Problem 2:   This problem compares the energy output and heat transfer to the environment by two different types of nuclear power stations—one with the normal efficiency of 36 %, and another with an improved efficiency of 47 %. Suppose both have the same heat transfer into the engine in one day, 2.5 × 1014 J  Part (a)  How much more electrical energy is produced by the more efficient power station?  Part (b)  What is the change in the heat transfer to the environment after the upgrade to the more efficient power station?

A sample of ideal gas in a thermally insulated container with a movable piston is initially in state A.  The gas is taken from state A to state B by an adiabatic process.  The dashed lines represent isotherms.  If W is the work done on the gas, Q is the energy transferred to the gas by heating, and  Delta U be the change in the internal energy of the gas during the process. a) is W greater than zero, zero, or less than zero? Explain briefly  b) is Q greater than zero, zero, or less than zero? Explain briefly. c) is  Delta U  greater than zero, zero, or less than zero? Explain briefly.

You would like to raise the temperature of an ideal gas from 295 K to 960 K in an adiabatic process. a)What compression ratio will do the job for a monatomic gas?  b)What compression ratio will do the job for a diatomic gas?
