When Vicky woke up this morning it was -20 degrees C. When she arrived at school it was -5 degrees C. What was the numeric change and is it warmer or colder?
It is 15 degrees warmer.

Daily Double!
It is the average of the kinetic energy of all the molecules in the sample.
If you put a cup of hot water in a closed container of cold water, and you put a room temperature cup of water in a cup of cold water, which system will have the greatest difference in temperature?
The cup of hot with container of cold.

Daily double!
They will be the same.
