Measure of average kinetic energy particles in an object/substance.

Question 11

Melting Point

Answer 11

Specific melting temperature in crystalline solids.

Question 12

Freezing Point

Answer 12

Temperature a liquid turns into a solid.

Question 13

Vaporization

Answer 13

Change from liquid to gas.

Question 14

Boiling Point

Answer 14

Specific boiling temperature in liquids

Question 15

Condensation

Answer 15

Change from gas to liquid.

Question 16

Sublimation

Answer 16

Change from solid to gas.

Question 17

Thermometer

Answer 17

Instrument to measure temperature.

Question 18

Pressure

Answer 18

Force of an outward push over an area.

Question 19

Charle’s Law

Answer 19

At a constant pressure if temperature decreases then volume decreases. Temperature and volume have a direct relationship.

Question 20

Boyle’s Law

Answer 20

At a constant temperature is the pressure increases then volume decreases. Pressure and volume have an inverse relationship.

Question 21

Directly Proportional

Answer 21

As one variable decreases the other decreases the same rate (vice versa and applies the same to an increase).

Question 22

Inversely Proportional

Answer 22

As one variable increases the other decreases. (vice versa).
