Relating temperature and energy Compare the energy content

Temperature certainly has something to do with energy, but the two concepts are distinct. Here is an activity that will help reveal the differences:

Materials:

Suppose we fill cup A almost full of hot water and fill cup B one-quarter full of hot water. Predictions
*If we had warmed the water for these in separate pans on the stove, which would take longer?
(Click on one of the choices to mark your opinion)
Cup A would take longer About the same length of time Cup B would take longer
*Which one do you think contains the most energy? Cup A They are the same Cup B
 
*Predict: what will you find when you measure the
temperatures of the water in the two cups?
Cup A is cooler They are the same Cup B is cooler
 
Now let's do the experiment. Fill cup A almost full of hot water; fill cup B one-quarter full of hot water. Results
*Are the temperatures different? Yes Not very different No, they are rather different
Wait a few minutes and measure the temperatures again.
*How do the temperatures compare now? Cup A is cooler They are the same Cup B is cooler
