1
Q

What is the kinetic molecular theory?

A

The kinetic molecular theory explains that all matter is made of particles.

2
Q

What is kinetic energy?

A

Kinetic energy is the energy of a particle or object due to its motion.

3
Q

What are 3 ways that kinetic energy is measured?

A

temperature
thermal energy
heat

4
Q

What is temperature?

A

The measure of average kinetic energy of all particles in a sample of matter.

5
Q

What happens to the temperature when average kinetic energy increases?

A

temperature increases.

6
Q

What are the 3 different scales temperature is measured on?

A

fahrenheit
celcius
kelvin

7
Q

What is thermal energy?

A

Thermal energy is the total energy of all particles in a solid, liquid, or gas.

8
Q

The more kinetic energy… (thermal energy)

A

The more thermal energy

9
Q

What is heat?

A

Heat is the amount of thermal energy that transfers from an area/object of high temp to low temp.

10
Q

What are 3 ways that heat is transferred?

A

conduction
convection
radiation

11
Q

What is conduction?

A

the transfer of heat from one substance to another.

12
Q

What is convection?

A

the transfer of heat within a fluid, where the fluid moves form place to place.

13
Q

What is radiation?

A

the transfer of heat by electromagnetic waves that carry radiant energy.

14
Q

What is radiant energy?

A

the energy carried by electromagnetic waves

15
Q

What is one example of infared radiation?

A

when you stand close to a campfire and it emits electromagnetic waves.

16
Q

What are 3 sources of earth’s energy?

A

solar radiation
residual thermal energy
radioactive decay
