Q1. If a metric ton is 1.000 x10^3 kg, how many 72 kg people can safely occupy an elevator that can hold a maximum mass of accurately 1 metric ton?

Q2. The rms speed of the molecules in 1.0 g of hydrogen gas is 1800 m/s.

A) What is the total translational kinetic energy of gas molecules?

B) What is the thermal energy of gas?

C) 500 J of work are completed to compress the gas while, in the same process, 1400 J of heat energy are transferred from the gas to the environment. Afterward, what is the rms speed of the molecules?
