Question image

What happens to the temperature of a substance when kinetic energy decreases?


1

The temperature decreases.


2

The temperature is not related to kinetic energy.


3

The temperature increases.


4

The temperature stays constant.

media
media

​The transfer of energy from one particle of matter to another particle of matter.

​​Conduction

The transfer of thermal energy by the movement of a fluid (a gas or a liquid).

​​Convection

​The transfer of energy by electromagnetic waves (light energy waves).

Radiation​

3

Conduction

Energy transfer between particles of matter that touch directly.

  • As heat is added to a material, the particles begin to vibrate more which means kinetic energy increases.

  • Conduction happens through direct touch/contact between objects.​

4

Multiple Choice

Which of the following is an example of conduction?

1

Making pancakes on a stove.

2

Microwaving your left overs.

3

Water at a rolling boil.

4

Heat coming from the sun.

5

Convection

Heat transfer through movement of fluids.

  • Fluids are materials that can flow, like liquids and gases.

  • The particles at the bottom heat up and become less dense. This causes them to rise and push the colder and denser molecules down.

  • This movement is called a Convection Current​

6

Multiple Choice

Which of the following is an example of convection?

1

Making pancakes on a stove.

2

Microwaving your left overs.

3

Water at a rolling boil.

4

Heat coming from the sun.

7

Multiple Choice

What causes a convection current and keeps it going?

1

Hot particles sink, causing the cold particles to rise.

2

Cold particles steal the heat from the hot particles.

3

Hot particles rise, pushing the cold particles down toward the heat source.

4

Convection currents do not move at all.

8

Radiation

Heat transfer by electromagnetic waves.

  • The only form of heat transfer that does not require matter.

  • Heat you can feel but do not always see.

  • This is how we receive heat from the sun since it is able to pass through the vacuum of space where there is not matter present for it to travel through.

9

Multiple Choice

Which of the following is an example of radiation?

1

Making pancakes on a stove.

2
