Thermal Energy Study

Molecules are made out of...

What happens when the temperature increases?

• Atoms/molecules move faster!

• Atoms/molecules move slower!

• It doesn't matter, they speed doesn't change

When something goes slower... does it have LESS or MORE energy?

• Less energy

• More energy

• Energy stays the same

Are thermal energy and temperature the same thing

• Yes

• No

How do you get the TOTAL energy of something?

• Add up all the numbers in the molecules

• Divide the molecules by any number you want

• Add up everything and then divide

If something has a HIGHER temperature, does that mean it has more thermal energy?

• No, not always

• Yes, always

What is kinetic energy?

• how much heat something has

• the amount of molecules in an object that are moving

• when molecules move slow

• when something loses heat

What is the definition of a scientific model?

• something that represents an object in a different way & helps explain how something works

• its something that you look at for fun

• its a diagram of the solar system

• molecules

What is something that has a high temperature?

• Cup of ice water

• The floor in a classroom

• A cup of warm soup

The TOTAL energy of something is 20, and there are 5 molecules... what is the average kinetic energy?
