1. A sample of an ideal gas has a volume of 2.26 L at 278 K and 1.10 atm. Calculate the pressure when the volume is 1.80 L and the temperature is 303 K. 2. The volume of a sample of hydrogen gas was decreased from 10.76 L to 4.05 L at constant temperature. If the final pressure exerted by the hydrogen gas sample was 8.39 atm, what pressure did the hydrogen gas exert before its volume was decreased? 3....
According to the ideal gas law, a 9.843 mol sample of argon gas in a 0.8425 L container at 502.0 K should exert a pressure of 481.3 atm
Hint: % difference = 100×(P ideal - Pvan der Waals) / P idealAccording to the ideal gas law, a 9.843 mol sample of argon gas in a 0.8425 L container at 502.0 K should exert a pressure of 481.3 atm. By what percent does the pressure calculated using the van der Waals' equation differ from the ideal pressure? For Ar gas, a =1.345L2 atm/mol2 and b = 3.219×10-2 L/mol.

A fixed amount of ideal gas is held in a sealed container. The initial volume, pressure, and temperature are [recall that 1L = 10−3 m3, and 1atm = 101,300Pa] V = 40 L P = 2.5 atm T = 400 K. (a) Compute the new temperature if the pressure is reduced to P = 1.0atm while the volume is held constant. (b) Compute the new volume if the temperature increases to 600K while the pressure is reduced to 2.0atm. (c)...

Consider a piston cylinder process in air (as an ideal gas with constant specific heats) which goes from state 1 at 1 atm, 300 K to state 2 at: 3 atm and 400K. (use k=1.4, Cp = 1.005 kJ/(kg K), Cv=0.718 kJ/(kg K), R= 0.287 kJ/(kg K)) (these are the same conditions as question 4). What must the heat transfer be (in kJ/kg), if the process takes place without entropy generation and it can be assumed the temperature at system...
