• They are getting smaller

• They are getting bigger

• They are moving slower

what change of state do you observe when water vapor came into contact with the lid?

• Freezing

• Melting

• Evaporation

• Condensation

Tags

NGSS.MS-PS1-4

This is condensation. The change of this state occurred because the water vapor...

• was less exposed to the sun

• was confined by a lid

• came into contact with a cool surface

• was trapped and heated

In the gas state, the water particles...

• move quite rapidly and sometimes collide

• move more slowly than in a liquid water

• hover and stick to each other

• never come near to each other

Tags

NGSS.MS-PS1-4

unlike liquid water, water vapor can spread everywhere because the particles...

• move freely in all direction

• are smaller than they were in the liquid

• are not in any pattern

• are larger than they were in the liquid
