1. An ideal gas at initial pressure PF4PA and temperature T=200K expands isothermally to 3 times its original volume. The gas is then further reduced in pressure at constant volume to pf1Pa. What is the final temperature of the gas, Tf? (hint: draw the multi-step process on a pV diagram.) А. 35K В. 150K С. 200K D. 300K E. 600K

A copper (B = 51x10-6 (Cº)-1 ) cylinder is initially at 30.0C.At what temperature will its volume be 0.20% larger than it is at 30.0°C? O a. 36.3°C O b. 29.4°C O c. 49.4°C d. 69.2°C e. 74.6°с

7. Containers A and B in the figure to the right hold the same gas. The volume of B is four times the volume of A. The two containers are connected by a thin tube (negligible volume) and a valve that is closed. The gas in A is at 300 K and pressure of 1.0 × 10³ Pa. The gas in B is at 400 K and pressure of 5.0 × 105 Pa. Heaters will maintain the temperatures of A and B even after the valve is opened A 300 K Valve B 400 K a) After the valve is opened, gas will flow one way or the other until A and B have equal pressure. What is the final pressure? b) Is this a reversible or an irreversible process? Explain..

1. Given 14.00 L of a gas at a pressure of 5.10 atm, what will the volume be if I increase the pressure to 10.50 atm while keeping the temperature constant? 2. Given an initial pressure of 500. atm and a temp. of 150C, what will the pressure be if I increase the temp. to 275⁰C, while keeping the volume constant? 3. Given an initial volume of 20.5 L and a temp. of 50.0 ⁰C, what will be the new volume if the temp. increases to 100 ⁰C, while keeping the pressure constant?

1.  The internal energy for a monatomic gas is equal to its total translational kinetic energy. 2 moles of Helium (monatomic gas, atomic mass = 4 u) are placed in a .1 m3 container and are at 60 kPa.a. Find the total translational kinetic energy?

4. Ideal Gas Type Question: A piston comprises two nested cylinders which are 3 cm and 2.8 cm in diameter with 0.1 cm thick walls and are each 1 m long. Initially, the smaller cylinder sits completely inside the larger cylinder and is filled with N2 at 20 °C and atmospheric pressure. a. C. The gas is slowly heated, while the cylinder is allowed to freely expand. What kind of process is this? banc b. The smaller cylinder has a total mass of 1.5 kg. What temperature does the gas need to be for the cylinder to become fully extended? The cylinder can withstand an internal pressure of 20 atm. What's the maximum weight it can lift? e. d. A 100 kg weight is dropped on the cylinder while it is fully extended, causing it to rapidly compress. What kind of process is this? If the cylinder is fully depressed by this event, what is the peak pressure? The adiabatic constant for N2 is 7/5. f. If the weight is dropped from 2 m, assuming 1% of its energy is converted into thermal energy in the gas,…
