1: If substances have the same temperature they have the same temperature .
2: Insulators tend to have (high or low) specific heats because it takes a (large or small) amount of energy to change the temperature.
3: Conductors tend to have (high or low) specific heats because it takes a (large or small) amount of energy to change the temperature.
4: Thermal energy always flows from (hotter to colder or colder to hotter).
5: When is thermal equilibrium reached? What tells us something is at thermal equilibrium?
6: Explain the relations between the following variables (hint: look at your specific heat demonstration assignment.
a: Mass and change in temperature
b:Specific heat and change in temperature
c:Energy and change in temperature
