Question 8

Solution

The rms speed of the molecules in 1.8 g of hydrogen gas is 1600 m/s.


Part A: What is the total translational kinetic energy of the gas molecules?
Express your answer to two significant figures and include the

appropriate units.

 

Part B: What is the thermal energy of the gas?
Express your answer to two significant figures and include the appropriate units.

 

Part C: 500 J of work are done to compress the gas while, in the same process, 1900 J of heat energy are transferred from thegas to the environment. Afterward, what is the rms speed of the molecules?

 

Express your answer to two significant figures and include the appropriate units.
