100
This is what you call a number that summarizes a set of data and that can be computed by adding all the numbers in a list and then dividing by the number of numbers in the list.

What is an Average? 

100

When a thing gets hotter, are the molecules moving faster or slower?

What is Faster?

100

This is what scientists define as the ability to make something move or change. 

What is Energy?

100

The molecules of a system will transfer energy until the system reaches a stable state known as _______________. 

What is Equilibrium? 

200

This term describes when something becomes different over time.

What is Change?

200

When a thing gets cooler, are it's molecules moving faster or slower?

What is Slower?

200

This is what scientists describe as a balanced state in which a system is stable, such as when two or more samples are at the same temperature. 

What is Equilibrium? 

200

Energy is not created or destroyed, it can only be ______________.

What is transferred?

300

This is what you call the moment when two objects hit each other. 

What is a Collision?

300

Temperature is a measure of the average ____________________ of the molecules of a thing.

What is Kinetic Energy?

300

This is what scientists call reaching a conclusion using evidence and reasoning. 

What is to Infer?

300

True or False: Hotter things always have more energy than colder things.

What is False?

400

The type of energy an object has if the object is in motion. 

What is Kinetic Energy?

400

When two things are in contact, thier molecules collide, and kinetic energy transfers from the _______________-moving molecules to the _______________-moving molecules. 

What is Faster to Slower?

400

This is what you call a group of atoms joined together in a particular way.

What is a Molecule?

400

For things at the same temperature, the thing with more molecules has more _________________ than the thing with fewer molecules.

What is Total Kinetic Energy OR Thermal Energy?

500

This is what scientists refer to as the total kinetic energy of all the molecules that make up a sample.

What is Thermal Energy?

500

In a state of equilibrium, all the molecules are moving at about the same or different speeds?

What is the Same?

500

Scientists use this word to describe something that has stayed mostly the same over time.

What is Stability?

500

Energy isn't created or destroyed. Therefore, as energy transfers in a system, the total energy of that system does not change. True or False?

What is True?
