Weather Review - Molecules

The molecules that make up a warmer material...

• have more kinetic energy than the molecules that make up a cooler material.

• have less kinetic energy than the molecules that make up a cooler material.

• move slowly.

• are packed closely together.

The amount of molecules that make up air remained the same in the closed system even when it was heated or cooled.

• True

• False

As air in the bottle is cooled down, the molecules that make up the air...

• take up more space

• increase in volume

• speed up and move faster

• slow down and take up less space

NGSS.MS-PS1-4

As air in the bottle is warmed up, the molecules that make up the air...

• speed up and spread out

• slow down and compact

• decrease in volume

• take up less space

Sunlight warms the ground through

• radiation

• reflection

• conduction

• temperature

Less dense air rises.

• True

• False

Heating the air makes the particles move faster and spread out, making it

• cooler

• more compact

• more dense

• less dense
