Matter and Energy Unit 1 lesson 2

Heat is the_____ of thermal energy from one body to another.

Heat is the_____ of thermal energy from one body to another.

Temperature is the measurement of the average ______ energy of molecules in a substance.

Gage was playing video games in his room. After a little time passed, he began to smell a delicious, warm scent that he knew was his grandma's famous chocolate chip cookies. Why did he smell the cookies when they were baking and not when she was making them?

• The gas particles have a higher temperature after being in the oven, which means less kinetic energy so the particles aren't diffusing quickly.

• Lower temperature means less kinetic energy so no smell

• The gas particles have a higher temperature, which means more kinetic energy, so the particles are moving faster.

• they weren't baking so no kinetic energy

An ice cube melts in a warm drink. The ice cube is....

• gaining energy

• losing energy

All matter has motion. This is true because...

• motion is energy. Energy is movement and movement causes heat.

• motion is everything

• matter is everything

• matter is everywhere

It is the device used to measure temperature.

What is the thermometer measuring in?

• 
• 

When it is cold the atoms move...

• slow

• fast

• still

• there are no atoms

when it is hot the atoms move...

• slow

• fast

• still

• there are no atoms
