8.7 J of mechanical energy
What is the purpose of the inner and outer tubes of a thermometer?
The inner tube is thin in order to have a precise measurement, and the outer tube is there to both protect and magnify the inner tube.
What do you call something that does transfers heat well?
A Conductor.
What are the two types of nuclear reaction, and what do they mean?
Fission (splitting of a nucleus) and Fusion (combining two nuclei)
Where is the potential energy in Nuclear Energy?
The energy stored in an atom's nucleus.
Convert 62.6 degrees Farenheit to Celcius.
17 degrees Celcius.

What do you call something that does not transfer heat well?
An Insulator.
Where is the potential energy in Chemical Energy?
Stored in the chemical bonds of molecules.
How much heat is required to raise the temperature of 5 kilograms of water by 10 kelvin? (water's specific heat is 4,180)
209,000 Joules
How is conduction present in a fire place?
Sticking marshmallows, swords, wood, etc. in the fire.
How is convection present in a fire place?
The air around the fire is warmed and then moves up the chimney, so cold air moves down the chimney to take its place.
