Solving for n gives you the following:

\n\n

Plug in the numbers and solve to find the number of moles:

\n\n

So you have

\n\n

Now youre ready to use the equation for total kinetic energy:

\n\n

Putting the numbers in this equation and doing the math gives you

\n\n

So the internal energy of the helium is

\n\n

Thats about the same energy stored in 94,000 alkaline batteries.

Molecules have very little mass, but gases contain many, many molecules, and because they all have kinetic energy, the total kinetic energy can pile up pretty fast. ThoughtCo, Aug. 25, 2020, thoughtco.com/calculate-density-of-a-gas-607553. Simplified, this means that if you increase the temperature of a gas, the pressure rises proportionally. To find the density of the gas, you need to know the mass of the gas and the volume. As you know, gas pressure is caused by the collisions that take place between the molecules of gas and the walls of the container.
