The rms speed of the molecules in 1.9 g of hydrogen gas is 1800 m/s.a) What is the total translational kinetic energy of the gas molecules? (kJ)b) What is the thermal energy of the gas? (kJ)c) 500 J of work are done to compress the gas while, in the same process, 2000 J of heat energy are transferred from the gas to the environment. Afterward, what is the rms speed of the molecules? (m/s)
