Heat Test

Question 0

Thermal energy

Answer 0

Total amount of energy in the system calculated by average KE x the number of molecules

Question 1

Temperature

Answer 1

The thing we measure hot and cold with.

Question 2

Heat energy

Answer 2

Form of energy that is transferred by change in temp

Question 3

Celsius

Answer 3

Scale of temperature in Europe

Water freezes at 0 c and boils at 100

Question 4

Fahrenheit

Answer 4

Scale of temperature used in the US.

Freezing point at 32 c and boiling point at 212 c

Question 5

Kelvin

Answer 5

Same stats as the Celsius scale made by scientists

0 Freeze 100 boil

Question 6

Absolute zero

Answer 6

Coldest temperature any substance can reach.

Question 7

Heat

Answer 7

Representation of the type of thermal energy that flows between two objects

Question 8

Thermal equilibrium

Answer 8

What happens when two objects are in thermal contact for a long time. They transfer heat between each other becoming the same temperature.

Question 9

Joules

Answer 9

Unit for heat

Question 10

Calorie

Answer 10

Unit for heat

Question 11

Kilocalorie

Answer 11

Same as 1,000 calories.

Question 12

What does water do when frozen?

Answer 12

The water expands when frozen

Question 13

Condensation

Answer 13

Way of heat transportation

When heat is transferred by molecules bouncing into each other as the two objects are in contact.

Question 14

Convection

Answer 14

Way of heat transportation

When hot liquids and gasses flow through a fluid to distribute heat energy

Question 15

Radiation

Answer 15

Way of heat transportation

Method in which heat gets to earth from the sun without the presence of air molecules.

Question 16

Conductor

Answer 16

Materials that transfer heat well and have free electrons

Ex: metal

Question 17

Insulators

Answer 17

Materials that don’t transfer heat well, have tightly packed electrons
Ex: styrofoam,wood, plastic air.

Question 18

Convection current

Answer 18

When a fluid closest to a heat source will get hot become less dense then rise. When it gets to the top the fluid expands and cools which causes it to become less dense and sink.

Question 19

Matter phases

Answer 19

Solid, liquid, gas and plasma

Question 20

Boiling

Answer 20

When a liquid goes to a gas by adding heat

Question 21

Condensation

Answer 21

Matter goes from gas to liquid

Question 22

Freezing

Answer 22

Matter goes from liquid to solid

Question 23

Melting

Answer 23

Solid to liquid

Question 24

Question 25

M

Answer 25

Stands for mass

Question 26

C

Answer 26

Stands for Specific heat capacity

Question 27

Delta T

Answer 27

Stands for change in temp

Question 28
