1.) A known volume of ideal gas is contained in a cylinder fitted with a piston and held at constant pressure. If the temperature changes from 25oC to 100 oC, by what factor does the volume change?
2.) What pressure in mmHg is required to contain 0.021 moles of nitrogen gas in a 4.7 L container at a temperature of 24.°C?
3.) Modern vacuum techniques make it possible to reach a pressure of 1.00 x 10-10mm Hg in a laboratory system. What volume in milliliters would 1.139 x 106molecules of gas occupy at this pressure and standard temperature (0oC) ?
Hint: How do you get the moles?
4.) Dry ice is carbon dioxide in the solid state. 1.18 grams of dry ice are placed into a 4.49 L evacuated chamber that is maintained at 36.1°C. What is the pressure in the chamber in kPa after all the dry ice has sublimed into CO2 gas?
Hint: How do you get the moles?
5.) Find the temperature at which a molecule of hydrogen has an rms speed of 446 m/s. (Hint: Remember in Physics, mass is measured in kg)

A cylinder of monatomic ideal gas is sealed in a cylinder by a piston. Initially, the gas occupies a volume of 2.50 L and the pressure is initially 125 kPa. The cylinder is placed in an oven that maintains the temperature at a constant value. 80.0 J of work is then done on the piston, compressing the gas (in other words, the gas does -80 J of work). The work is done very slowly so that the gas maintains a...

A cylindrical canister fitted with a piston at one end contains an ideal gas and floats...
A cylindrical canister fitted with a piston at one end contains an ideal gas and floats at the surface of a freshwater lake, where the temperature is 300 K. The gas pressure inside the canister is just enough to balance atmospheric pressure, and so the piston does not slide downward. Initially the canister volume is 3.24 L . The canister is lowered into the lake until it is 12.0 m below the surface, where the temperature is 280 K. Ignore...

400 moles of an ideal monatomic gas are kept in a cylinder fitted with a light frictionless piston. The gas is maintained at the atmospheric pressure. Heat is added to the gas. The gas consequently expands slowly from an initial volume of 10 m3 to 15 m3. (a) Draw a P-V diagram for this process. (b) Is this thermodynamic process an isothermal expansion, an isobaric expansion or an adiabatic expansion? (c) Calculate the work done by the gas. (d) Calculate...
