Temperature And Thermal Energy

Question 1

Conduction

Answer 1

Heat transfer through materials by direct contact of matter. A thermal insulator is a material that conducts heat poorly.

Question 2

Internal energy

Answer 2

Energy associated with the random, disordered motion of molecules

Question 3

Unit of specific heat

Answer 3

Calorie

Question 4

Relationship between specific heat and temperature gain

Answer 4

Inversely related

Question 5

Radiation

Answer 5

Heat transfer by electromagnetic waves

Question 8

Thermal equilibrium

Answer 8

Have the same temperature

Question 9

Thermal radiation

Answer 9

Electromagnetic waves produced by objects because of their temperature

Question 11

Thermal energy

Answer 11

Sum of all kinetic energy of the molecules of a material

Question 12

Forced convection

Answer 12

Flow of gas or liquid is circulated by pumps or fans

Question 13

Methods of heat transfer

Answer 13

Conduction, convection, radiation

Question 15

Convection

Answer 15

Transfer of heat by the motion of liquids and gases

Question 17

Free convection

Answer 17

Flow of gas or liquid comes from differences in density and temperature

Question 19

Temperature

Answer 19

measure of average kinetic energy of the molecules of an object

Question 21

First law of Thermodynamics

Answer 21

In an isolated system, the total amount of thermal energy remains constant.
In a closed system the energy lost by one object is equal to the energy gained by the other. Contents eventually reach equilibrium.

Question 22

Specific heat

Answer 22

Is a property of a substance
