Chem Review Part 3

Anything that fills the shape of its container

• fluid

• gas

• liquid

• (aq)

Solid --> gas

• evaporation

• deposition

• sublimation

• melting

gas --> Solid

• evaporation

• deposition

• sublimation

• melting

It ______ to go from solid to gas

• takes energy

• releases energy

It ______ to go from gas to solid

• takes energy

• releases energy

The temperature and pressure at which all three phases exist at the same time.

• triple point

• critical point

• phase change diagram

• phase change

Temperature above which no amount of pressure could result in a liquid.

• triple point

• critical point

• phase change diagram

• phase change

Gas particles do not attract or repel each other and the particles are much smaller than the space between them is apart of kinetic theory.

• true

• false

1.) Gas particles are in constant motion

2.) Gas particles move in a particular path

• 1.) true

  2.) false (the motion is random)

• both are true

• 1.) false (some particles stay in the same place)

  2.) true

• both are false

1.) No kinetics energy is lost with gas particles collide with each other or the walls of their container.

2.) All gases have the same average kinetic energy at the same temperature

• both are false

• 1.) false (some energy is lost)

  2.) true

• both are true

• 1.) true

  2.) false (they have different kinetic energy bc they move at different speeds)
