What is the difference between thermal energy and temperature? 

Awesome! Glad it helped.

Thanks for the comment! In this example I am making a relative comparison between the thermal energy of the pool and the cup of coffee based on the temperature only. The coffee has a much higher temperature than the pool but it has far less particles (molecules) than the pool. Since thermal energy is the total of all the energy of all the particles in a sample, the pool has much greater thermal energy than the coffee. I did not consider gravitational/positional energy in this equation. That would be an interesting thing to consider. How high would the coffee have to be in order to have equal thermal energy to the pool? Probably pretty high! Have a great day!

Glad it helped!

Don't worry, you got this. Just focus on the difference between the average of a set of numbers and the total of a set of numbers. The average is like the temperature and the total is like the thermal energy.
