Why do the clear cup and the black cup both have the biggest increase in temperature?
They both heat up, but for very different reasons.
Tell me why the black cup heats up differently from the clear cup.
You can use these words in your answer: light, transmitted, absorbed

Question 12
12.
If we had a cup cold of water out in the sun, what could you do to the cup to keep it from warming up?
When looking at the the data from the chart, the black cup amount of light reflects 425 lux of light and transmits 0 lux of light. That means 1,350 lux of light is not being transmitted or relfected....
Where is the rest of the light going?
It is being reflected off of the lid and foil.
It is being absorbed by the cup.
Looking at the data below, why would we put the cups in the dark if we were trying to test what effect light has on the temperature?
The dark is the control group used to see if light really does affect the temperature of the water.
The dark is the dependent variable in the experiment.
Which way does heat travel?
From hot to cold
From cold to hot
What do you think is going to happen to the water inside of the cup and the water in the water bath below?
The water inside and outside will warm up.
The water inside will stay the same and the water outside will cool down.
The water inside will warm up and the water outside will cool down.
Why do you think the cups in the dark still had an increase in temperature if there was no light?
Some light was in the dark room
The temperature of the air affected the temperature of the cup.
The water inside the cups in the dark was colder than the ones in the light.
At higher temperatures, molecules move....
faster
slower
the same speed
What happens when particles collide? Choose all of the answers that apply.
One particle slows down and the other speeds up
One particle gains energy and the other looses energy
None of these
What does temperature measure?
The energy of the particles in a substance
How hot something is
How cold something is
At lower temperatures, molecules move....
faster
slower
the same speed
Question 11
11.
What is happening to the thermal energy in this system over time (what is the system trying to reach)
The energy is being passed until all the particles have the same energy
The energy is passed from the particles with the lowest energy to the highest.
