Answer 14

The temperature at which a substance changes from a liquid to a gas

Question 15

Condensation

Answer 15

The change from the gaseous to the liquid state of matter

Question 24

How fast does a liquid with HIGH viscosity flow?

Answer 24

It flows slowly

Question 25

How fast does a liquid with LOW viscosity flow?

Answer 25

It flows quickly

Question 26

How do gas particles move

Answer 26

The gas particles spread apart filling all the space available

Question 27

During sublimation, do the particles of a solid pass through the liquid state of matter as they form a gas?

Answer 27

NO.

Question 28

What happens to a solid as it melts?

Answer 28

As the solid gains thermal energy, it's molecules vibrate faster, raising the temperature of a substance
