Compressed air can be pumped underground into huge caverns as a form of energy storage. The volume of a cavern is 6.3 x 105 m³,5and the pressure of the air in it is 7.4 × 106 Pa. Assume that air is a diatomic ideal gas whose internal energy U is given by U = nRT.If one home uses 30.0 kWh of energy per day, how many homes could this internal energy serve for one day?

From ideal gas law,Thus, we can find the internal energy to be,

Three moles of an ideal monatomic gas are at a temperature of 381 K. Then 2959 J of heat is added to the gas, and 651 J of work is done on it. What is the final temperature of the gas? Number Units the tolerance is +/-2%
A sample of a monoatomic ideal gas has a pressure of p and volume V. When the gas is warmed, it’s pressure triples and volume triples. This warming process includes two steps, the first at constant pressure and the second at constant volume. Determine the amount of energy transferred to the gas by heat.
A sample of helium behaves as an ideal gas as it is heated at constant pressure from 273 K to 386 K. If 24.0 J of work is done by the gas during this process, what is the mass of helium present?
A gas expands from I to F in the figure below. The energy added to the gas by heat is 212 J when the gas goes from I to F along the diagonal path. Three paths are plotted on a PV diagram, which has a horizontal axis labeled V (liters), and a vertical axis labeled P (atm). The green path starts at point I (2,4), extends vertically down to point B (2,1), then extends horizontally to point F (4,1). The blue path starts at point I (2,4), and extends down and to the right to end at point F (4,1). The orange path starts at point I (2,4), extends horizontally to the right to point A (4,4), then extends vertically down to end at point F (4,1).
