1. ________________________________is a switch in a thermostat.
2. ________________________________is an instrument used to measure temperature.
3. ________________________________is the movement of the particles in an object.
4. ________________________________is an increase in size of a substance, caused by heat.
5. ________________________________is the transfer of thermal energy in a substance.
6. ________________________________is a measure of the average kinetic energy of the
molecules of a substance.
7. What is a calorie? __________________________________________________________
__________________________________________________________________________
8. Heat is ________________________in units called __________________________ or
________________________.
1 calorie = 4.19 J.
9. Insulators are substances that ___________________________conduct thermal energy well.
List 4 examples:
10. Conductors are substances that ___________________________thermal energy well.
List 4 examples:
11. Thermostats are devices that ___________________________temperature.
12. The Bimetallic Strip makes the ____________________________go on and off.
Three Types of Heat Transfer:
13. ___________________________ - transfers the thermal energy by the movement of liquid
or gas - usually in up and down currents. An example is ___________________________.
14. _______________________ - energy transferred by electromagnetic waves, without
needing a medium (solid, liquid, gas). Transfers through __________________________.
15. _______________________ - transfer of energy from one substance to another - usually in
a solid to solid, solid to liquid or liquid to liquid. ________________ contact of molecules.

Thermal Expansion and Contraction
When temperature increases, ____________________ _____________________takes place as
an object or substance absorbs more thermal energy. This is true of most substances.
When temperature decreases, ____________________takes place in most substances, because
the ______________________ move more slowly, and so they cannot move as far __________.
Water, however, is different. When water loses thermal energy and freezes, it
___________________, instead of contracting. This is unlike most other substances.
General concepts:
More mass = more ____________________ of molecules
More motion of molecules = more ________________ _____________energy;
More thermal energy = ________________________temperature.
1 Food Calorie = ___________ calories, which is equal to _____Kilocalorie
