Q

Sublimation

A

When a solid gains enough energy to change to the gas state

17
Q

Pressure

A

The force exerted on a surface divided by the total area over which the force is exerted

18
Q

Boyle’s Law

A

A principle that describes the relationship between the pressure and volume of a gas at constant temperature

19
Q

Charles’s Law

A

A principle that describes the relationship betweenm the temperature and volume of a gas at a constant temperature

20
Q

What is the equation to find PRESSURE

A

Force / Area

21
Q

What is the equation to find AREA

A

b x h

21
Q

What is the unit

A

Pascale’s / Pa

22
Q

What are three examples of a Crystalline solid?

A

Table sugar, table salt, and snow

23
Q

What is surface tension caused by

A

The inward pull of the molecules making up a liquid

24
Q

How fast does a liquid with HIGH viscosity flow?

A

It flows slowly

25
Q

How fast does a liquid with LOW viscosity flow?

A

It flows quickly

26
Q

How do gas particles move

A

The gas particles spread apart filling all the space available

27
Q

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

A

NO.

28
Q

What happens to a solid as it melts?

A

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

29
Q

How does vaporization take place?

A

When the particles of a liquid gain enough energy to form a gas

30
Q

What are the two types of vaporization?

A

Boiling and Evaporation
