Vocabulary
This can be found by adding all of the numbers to get a total and then dividing by the number of numbers that were added.
What is Average?
This is the direction energy transfers in
What is hot to cold?
A can of soda has been in a hot car all day. The temperature of the can of soda has increased, so this is what has happened to the molecules in the can of soda.
What is move faster?
Thermal Energy
1 2 3
What is 6?
The name of Mr. Hwang's cat
Who is Momo?
This is the type of energy that an object has because it is moving.
What is Kinetic Energy?
When objects get colder, they move _______.
What is slower?
When water freezes in a freezer, the temperature has decreased. This is what has happened to the energy of the molecules of water.
What is "They have decreased"?
Temperature
1 2 3
What is 2?
Water is an example of this because is has 2 parts Hydrogen and 1 part Oxygen (it is made of atoms joined together).
What is a molecule?
The average kinetic energy of an object
What is temperature?
Energy is not created or destroyed. Instead, it does this.
What is transfer?
Object A has 3 times more mass than Object B. Object A and B are the same temperature. Object C is colder than Object B and A. This object will increase the equilibrium temperature of Object C more when it they touch.
What is Object A?
Thermal Energy
2 7 4 8
What is 21?
When two objects have the same temperature of substance, but one of the objects is larger, it is said to have more of this type of energy.
What is total kinetic energy/thermal energy?
This is when something stays mostly the same over time.
What is stability?
This is means the amount of stuff or molecules something has. The thermal energy increases as this increases.
What is mass?
A hot glass of water (Container A) and a cold glass of water (Container B) were placed together. This is what happened to the temperature of each container to reach equilibrium.
What is "Container A got colder (or decreased temperature) and Container B got warmer (or increased temperature)"?
Temperature
2 4 6 8
What is 5?
This is how molecules are able to transfer energy from one object to another.
What is collision/touching? (either answer or close to is accepted)
This is the balanced state in which a system is stable, such as when two or more samples are at the same temperature.
What is equilibrium?
At _______, the temperature is the thermal energy evenly divided by the number of molecules in the system.
What is equilibrium?
You have a bowl of soup and a cup of soup? They are both the same temperature. You bring both of them to school. Which one will get cold quicker?
What is the cup of soup?
Object A has a Thermal energy of 10 and has 1 molecule. Object B has a Thermal energy of 15 and has 4 molecules. This is the temperature of the entire system (both molecules) at equilibrium?
What is 5?
This is how to calculate the average kinetic energy of a substance.
What is total kinetic energy DIVIDED by the number of molecules? (written formulas are also accepted
