1.00 moles of a gas is at a temperature of 273 Kelvin and has a pressure of 1.00x105Pa.

  1. What is its initial volume?
  2. STEP 1: Its pressure is doubled while keeping its volume constant. What is its temperature after this step?
  3. STEP 2: Its temperature is held constant while it it is reduced back to its initial pressure. What is the the volume after this step?
  4. Draw a PV diagram showing the two step (it doesn’t have to have numbers, just qualitatively correct)
  5. What is the work done by the 2 Steps (in Joules)?

The ideal gas law PV=nRT relates pressure P, volume V, temperature T, and number of moles of a gas, n. The gas constant R equals 0.08206 L⋅atm/(K⋅mol) or 8.3145 J/(K⋅mol). The equation can be rearranged as follows to solve for n: n=PVRT This equation is useful when dealing with gaseous reactions because stoichiometric calculations involve mole ratios.
