Sublimation

27
Q

During an ___ change, the system releases energy to its surroundings.

A

Exothermic

28
Q

____ Between the particles of a gas and the walls of the container cause pressure in a closed container of gas

A

Collisions

29
Q

During vaporization, a substance changes from a ___ to a ___.

A

Liquid;Gas

30
Q

How could you determine if a phase change is endothermic

A

If you can take the temperature of the surrounding area, and the temp. decreases.

31
Q

Explain why boiling water in a large pot on the stove has a temperature of 100°C even if it has been boiling for an hour

A

A phase change is taking place as the water boils to turn into a water vapor the temperature does not change

32
Q

What to phase changes occur between solid water and liquid water and at what temperature does each phase change take place?

A

Melting and freezing and it will take place at 0°C

33
Q

Why does the air pressure in a car tires increase after a long drive

A

The constant motion causes the air to warm up, which increases the kinetic energy leading to the colliding of the particles.

34
Q

What substance in figure 3-1 is a solid explain how you know

A

Substance A because particles are tight together and in a regular position.

35
Q

Compare the shape and volume of solids liquids and gases

A

Solids- Definite shape & definite Volume
Liquids- No definite shape & definite volume
Gas- No definite shape & no definite volume

36
Q

Name a describe the phase change that occurs when dry ice is placed in an open container at room temperature

A

Sublimation: at room temperature it changes from a solid carbon dioxide into a gas carbon dioxide

37
Q

What happens to the average quick energy of water molecules of water freezes

A

As water freezes it releases energy into its surroundings and the average kinetic energy decreases

38
Q

Describe what happens to the arrangement of water molecules as ice melts

A

At the melting point of water some molecules gain enough energy to move from their fixed positions

39
Q

Identify the phase change in figure 3 that are labeled A, B, And C

A

A:vaporization
B: melting
C:freezing

40
Q

Describe the two phase changes that can happen to a liquid.

A

Freezing- liquid to solid

Melting - solid to liquid
