#4 and #5 questions. Thank you! Initial Particle 60 Temperature 300 K avg. speed 465 m/s Initial pressure 7.1 atm Final Particle 160 Temperature 300 K avg. speed 455 m/s final pressure 18.6 atm

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..

You have a container of neon (Ne) gas at 290 K. The volume of the container is 0.1 m3 and the pressure is 2.1 atm. a) How many Ne atoms are in the container? b) How many moles of Ne are in the container?

Problem #1: An ideal gas of initial volume V=1m^3, initial temperature T=1000C and initial pressure P=10,000 Pa is heated up to a final temperature T=3000C and allowed to expand into a final volume V=3m^3. What is the final pressure?

A 2100 cm^3 container holds 0.15 mol of helium gas at 330C. 1. How much work must be done to compress the gas to 1400cm^3 at constant pressure?  2. How much work must be done to compress the gas to 1400cm^3 at constant temperature?

Two ideal gases have the same mass density and the same absolute pressure. One of the gases is helium (He), and its temperature is 131 K. The other gas is neon (Ne). What is the temperature of the neon?

1. Three moles of a monoatomic ideal gas are placed in a portable container with a volume of 4.10 x 10¬³ m3. The temperature of the gas is 165 °C. What is the average kinetic energy per molecule? sf60 s 60 ssfoc sf60 st ssf60

2.00 mol of helium and 1.00 mol of argon are separated by a very thin barrier. Initially the helium has 7500 J of thermal energy. The helium gains 2500 J of energy as the gases interact and come to thermal equilibrium by exchanging energy via collisions at the boundary. What was the initial temperature of the argon? First, what is the equilibrium temperature of the two gases? Express your answer in kelvins. ► View Available Hint(s) Tf = Submit Part B VE ΑΣΦ help What is the thermal energy of the argon at the equilibrium temperature?
