100
This can be found by adding all the numbers to get a total and then dividing by the number of numbers added.
Average
100
When an object's kinetic energy increases, the molecules start to move ___________.
Faster
100
A can of soda has been in a hot car all day. The temperature of the soda has gotten hotter, so what happened to the energy of the molecules in the soda can?
The energy has increased
100
Energy cannot be ________ or ____________.
Created or Destroyed
100
When something becomes different over time, it is known as this.
Change
200
This is the type of energy that an object has because it is moving.
Kinetic energy
200
When objects cool, the molecules begin to move _______________.
Slower
200
When liquid water freezes into ice, what happens to the energy of the molecules of water?
The energy decreases.
200
For substances to reach equilibrium, both objects have to transfer heat back and forth. True or false?
False (Hot substances transfer energy to colder)
200
How do you calculate thermal energy?
Add the kinetic energy of all the molecules in an object together to get the total kinetic energy
300
This is a measure of how hot or cold something is.
Temperature
300
Energy cannot be created or destroyed. Instead, it does this.
Transfer
300
If heat is transferred from Object A to Object B, which object has faster-moving molecules at the start?
Object A
300
A warm floor under steam pipes means the molecules in the floor gained _____.
Energy
300
Find the temperature of this object:
The temperature is 2
400
This is when something stays mostly the same over time.
Stability
400
How do you find the temperature of an object?
Find its average kinetic energy OR add up all the numbers to get the total, then divide by the number of numbers.
400
This is the name of the system that was chosen as the best option to warm up the air at Riverdale High School.
the groundwater system
400
Which has more thermal energy, a bathtub full of water at 50C or a small tea cup of water at 100C?
Bath tub
400
This vocabulary word is what happens when molecules run into each other.
Collision
500
This is the balanced state in which a system is stable, such as when two or more samples are at the same temperature.
Equilibrium
500
Molecules transfer energy until they reach this stable state.
Equilibrium
500
You heat up a large bowl of soup and a small cup of soup in the microwave. Both start at the same temperature. You leave them both out on the kitchen table. Which one will get cold quicker and WHY?
The cup of soup because it has less thermal energy
500
After a hot pancake sits on a plate for a while, what must be true about the pancake’s thermal energy?
It is decreased
500
How do you calculate the temperature of a substance?
Add up to find the total kinetic energy and divide it by the number of molecules
