The rms speed of the molecules in 1.7 g of hydrogen gas is 1700 m/s.
What is the total translational kinetic energy of the gas molecules?
What is the thermal energy of the gas?
500 J of work are done to compress the gas while, in the same process, 1700 J of heat energy are transferred from the gas to the environment. Afterward, what is the rms speed of the molecules?
