100
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?
100
When an object has greater kinetic energy, it is said the molecules have this speed.
What is faster molecules?
100
A can of soda has been in a hot car all day. The temperature of the soda has gotten hotter, so this is what has happened to the energy of the molecules in the soda can.
What is "They have increased"?
Or What is "they have gained greater energy"?
100
Energy is neither created nor destroyed, it transfers.
What is true?
100
When something becomes different over time, it is known as this.
What is change?
200
This is the type of energy that an object has because it is moving.
What is Kinetic Energy?
200
When objects get colder, the molecules are said to have this type of speed.
What is slower molecules?
200
When water freezes in a freezer, this is what has happened to the energy of the molecules of water.
What is "They have decreased"?
Or What is "They have lost energy"?
200
In order for substances to reach equilibrium, both of the objects have to transfer temperatures back and forth.
What is false? (Hot substances transfer to colder)
200
Thermal energy is a measure of this type of energy
What is a total kinetic energy?
300
This is a measure of how hot or cold something is.
What is temperature?
300
Energy is not created or destroyed. Instead, it does this.
What is transfer?
300
Lisa melted a candle to make an art project. Then, she placed the project by a fan to cool it off. This is the direction that energy is transferring.
What is "from the art project to the air".
Or What is "from hot to cold."
300
The hotter something is, the slower its molecules move.
What is false? (they move faster)
300
Find the average kinetic energy
What is average kinetic energy is 2?
400
This is when something stays mostly the same over time.
What is stability?
400
Temperature is a measure of this type of kinetic energy.
What is average kinetic energy?
400
This is the name of the system that was chosen as the best option to warm up the air in a school
What is "the groundwater system"?
400
When two substances start at the same temperature, the substance with a smaller amount will gain and lose heat at a faster rate than the substance with a larger amount.
What is true?
400
This is how molecules are able to transfer energy from one object to another.
What is collision/colliding?
500
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?
500
Molecules transfer energy until they reach this stable state.
What is equilibrium?
500
You have a bowl of soup and a cup of soup. Both are the same temperature. You bring both of them to school. Which one will get cold quicker?
What is the cup of soup?
500
Thermal energy is the average kinetic energy of a substance
What is false?
500
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
