When looking at a thermometer, how do we know heat has been absorbed? How do we know if heat has been lost?
Heat absorbed- Temperature rises.
Heat lost- Temperature decreases
100
When temperature decreases, what happens to the kinetic energy?
Kinetic energy also decreases (the molecules slow down)
100
Identify Conduction and Give 1 Example
Heat transfer from touch
Ex- Spoon in a hot Mug
100
Can Conduction work from a liquid to a solid?
Yes! As long as it touches
200
When copper is added to water, thermal energy between the copper and the water is transferred via what? (Conduction, Convection, Radioation)
Conduction
200
How would you increase the average kinetic energy of particles within a glass of water?
Heat it up! Microwave, stove, oven.
200
Identify Convection and Give 1 Example
Convection- Heat rises, cold sinks
Ex. Heated air in a room circulates
200
At what time did the molecules in the water reach their maximum level of kinetic energy?
6
300
Concerning Conduction, what is a way to increase the rate of heat transfer?
Increase the interaction area (area being touched)
300
Higher kinetic energy means what for temperature and movement?
Higher temperature and movement
300
Identify Radiation and Give 1 Example
Radiation- Light and electromagnetic waves
Ex- sunlight and microwave
300
Identify if the letters are increasing or decreasing in their Kinetic energy
A and C are increasing
B and C are Decreasing
400
1. Convection
2. Conduction
3. Radiation

Explain how a state of matter change is connected to kinetic energy and temperature.
The more kinetic energy, the higher the state of matter. More kinetic energy is gas. Low kinetic energy is solid
400
When a coffee is left in a car overnight, what will happen to the kinetic energy/ temperature?
It will decrease and come to a balance (equilibrium)
400
Who has the higher kinetic energy? Temperature?
A has higher kinetic energy and temperature

He timed how long it took each ice cube to melt and the water to reach room temperature, and found that the ice in the __________ melted the fastest. This is because there are _________ molecules that transfer thermal energy into the ice through __________.
water, more, conduction
