In an isobaric compression of an idea gas, a) the internal energy of the gas remains constant, b) no heat flows into the gas, c) no work is done on the gas, d) work is done on the gas, and/or e) work is done by the gas.

An ideal gas undergoes an isothermal expansion from one state to another. In this process determine the following (using the sign conventions on page 413):
- Q = 0, Q > 0 or Q < 0
- W = 0, W > 0 or W < 0
- ΔU = 0, ΔU > 0 or ΔU < 0

An ideal gas undergoes an isothermal process. Which of the following are true (may be more than one): a) No heat is added or removed from the gas, b) the internal energy of the gas does not change and/or c) the average kinetic energy of the molecules does not change.

An ideal gas undergoes an adiabatic expansion in which no heat flows into or out of the gas. As a result determine which of the following properties of the gas increases (may be more than one): a) temperature, b) pressure and/or c) volume.

Can you cool your kitchen by leaving your refrigerator door open? Why or why not?

If 1500 J of heat is added to a system and the system does 1100 J of work, then what was the change in the internal energy of the system? Assume the system is closed (i.e. a gas inside of a cylinder fitted with a movable piston).

A gas undergoes an isothermal expansion from V1=1.4L followed by isobaric compression, p=cst. if p1=4.4atm, p2=2.2atm→?Nm2, calculate the total work done by the gas. Hint: W=∫dW=∫pdV=∫nRTVdV

Check all the correct statements. The internal energy of an ideal gas (those that obey PV = nRT) depends only the temperature of the system. The internal energy of any gas depends only the temperature of the system. The heat capacity of an ideal gas does not depend on what molecules the gas is made of. At constant temperature, the internal energy of a real gas increases with increasing pressure because molecules are closer together. We assume that the conditions...

An ideal gas is brought through an isothermal compression process. The 3.00 mol of gas goes from an initial volume of 222.0 × 10 − 6 m 3 to a final volume of 123.5 × 10 − 6 m 3 . If 7.60 × 10 3 J is released by the gas during this process, what are the temperature T and the final pressure p f of the gas

Internal energy change is the sum of heat and work. Explain why the internal energy change of the reaction between hydrochloric acid and sodium hydroxide can be determined with only a small error by determining the heat of the reaction. Explain why the error woul d be larger if sodium carbonate is used as the base in place of the sodium hydroxide.

At the beginning of compression of an ideal Diesel cycle the gas has a temperature and pressure of 400C and 90 kN/m2, respectively. The volume ratio of compression is 16:1. The maximum temperature of the cycle is 14000C. Determine, for the cycle, the pressure and temperature at each of the cycle process change points, [8] the work done/kg gas, [4] the thermal efficiency, [4] the work ratio, [3] the mean effective pressure,...

A gas turbine operates with two stages of compression with an intercooler between the stages. Air enters the first stage at 100 kPa and 300 K. The pressure ratio across each compressor stage is 5 to 1 and each stage has an isentropic efficiency of 85%. Air exits the intercooler at 330 K. The maximum cycle temperature is 1500 K and the cycle has a single turbine stage that works isentropically. Calculate the mass flow rate of the air if...
