How can I smell things from a distance Unit 3 IC1 LS3 (L10-L16)

What happens when you apply thermal energy (heat up something)?

• The molecules move faster

• The molecules slow down

• The molecules stop moving

When you mix two substances together, and one is warmer than the other, what will be the outcome (result)?

• The faster molecules of the hotter substance will collide with the slower molecules from the colder substance, And eventually, they will reach the same temperature (speed)

• They will not mix, since a hot substance and a cold substance will not interact, due to the fact that the colder molecules are not moving

Hot things have ____________ thermal energy than cold things

• more

• less

• same

• potato

All matter is made up of atoms that are constantly moving

• True

• False

Which state of matter has the highest kinetic energy (atoms move the fastest)?

• solid
• liquid 
• gas

All odors move in the same manner

• True

• False

Smelling an odor is important, because

• you could smell something burning and protect yourself.

• you could smell rotten food and not eat it.

• you could smell a dangerous gas and move away from it.

• all of the above.

All odors move by

• attaching on to matter and being carried to different areas.

• becoming part of the air and spreading out from the source.

• doing nothing, actually odors don't move. People move to the odor.

• sinking to the ground and embedding themselves in the flooring.

The three most recognized states of matter are...

• solid

• liquid

• gas

• air

Which takes the shape of its container?

• liquid
