A sample of argon gas (39.948 u) contains 2.41×1022 atoms of argon. The gas is initially at a pressure of 0.950 atm and a temperature of 298 K but then expands isobarically by 475 cm3 . (a) How many moles of argon gas are present? (b) What is the initial volume of the gas (in L)? (c) Calculate the work (in Joules) done by the gas during this process. (d) What is the final temperature (K) of the gas (after the expansion)? (e) What is the rms velocity (m/s) of the argon atoms before the expansion?

A flexible balloon contains 0.350 mol of an unknown polyatomic gas. Initially the balloon containing the gas has a volume of 6900 cm3 and a temperature of 30.0 ∘C. The gas first expands isobarically until the volume doubles. Then it expands adiabatically until the temperature returns to its initial value. Assume that the gas may be treated as an ideal gas with Cp=33.26J/mol⋅K and γ=4/3. What is the total heat Q supplied to the gas in the process? What is...

An ideal monatomic gas initially has a temperature of 267 K and a pressure of 6.14 atm. It is to expand from volume 488 cm3 to volume 1610 cm3. If the expansion is isothermal, what are (a) the final pressure and (b) the work done by the gas? If, instead, the expansion is adiabatic, what are (c) the final pressure and (d) the work done by the gas?

50 moles of argon gas initially at 350 K and 22 atm are expand isothermally to 25 atm. Find (a) the final volume of the gas, (b) the work done by the gas, (c) and, the thermal energy transferred. Consider the argon to behave as an ideal gas. Advice: As always, you must have to match the units in your calculation. Write the process in detail. Don't write cursive.
