Term
What does temperature depend on?
Definition
Kinetic energy of particles
Term
What is all matter made of?
Definition
Atoms or molecules
Term
3. T or F : Particles of matter are constantly moving.
Definition
TRUE. Particles are always moving, but they don’t all move at the same speed or same direction
Term
4. The more kinetic energy the particles of an object have, the higher the
____________________of the object.
Definition
temperature
Term
5. What instrument do we use To measure temperature?
Definition
Thermometer
Term
6. Thermometers can measure temperature because of what?
Definition
Thermal Expansion
Term
What are the three temperature scales and which one do we use more often in science?
Definition
Fahrenheit
Celsius - used in science more often
Kelvin
Term
8. What is the lowest temperature on the Kelvin scale?
Definition
Absolute Zero
Term
9. When temperature drops does expansion or contraction occur?
Definition
Because thermal expansion is the increase in volume of a substance, most things expand when heated and contract when temperature drops.
Term
10. If heat is a transfer of energy, what form of energy is being transferred ?
Definition
Thermal energy
Term
11. What SI unit do we use to express energy ?
Definition
joules (j)
Term
12. Which has more energy, anobject at a high temperature or a low temperature ?
Definition
An object at a high temperature.
The particles are moving faster.
Term
13. What is it called when objects have the same temperature ?
Definition
Thermal equilibrium
Term
14. What are three types of energy transfer?
Definition
Conduction
Convection
Radiation
Term
15. What type of energy transfer occurs through direct contact?
Definition
Convection
Circular motion of gases or liquids
Term
16. What type of energy transfer occurs through matter or space As electromagnetic WAVES?
Definition
Radiation
Term
17. What do you call substances that conduct thermal energy very well?
Definition
Conductors
Term
18. What do you call substances that DO NOT conduct thermal energy very well?
Definition
Insulators
Term
19. What are the states of matter?
Definition
The physical forms in which something can exist.
Solid, liquid, gas
Term
20. What does change of state mean?
Definition

Solid to liquid
Term
22. What is freezing point?
Definition
Liquid to solid
Term
23. What is boiling point?
Definition
Liquid to gas
Term
24. What is condensation point?
Definition
Gas to a liquid
Term
