If the pressure of an ideal monatomic gas is increased while the number of moles is kept constant, what happens to the average translational kinetic energy of one atom of the gas? Is it possible to change ?both the volume and the pressure of an ideal gas and keep the average translational kinetic energy of the atoms constant? Explain.
Solution to 17DQ When the [pressure of the ideal monoatomic gas is increased by keeping the number of moles as a constant, the temperature will increase thus the average kinetic energy will also increase. PV=nRT P=2N(Average KE)/3V So as P increases, average KE will also increase. Yes, it is possible to change pressure and volume of the ideal monoatomic gas without changing the temperature. This is possible if the expansion is isothermal in nature, where nRT is kept constant.
