Matter and Physical Changes

Molecules have the least kinetic energy in a

• solid

• liquid

• gas

Kinetic energy is

• the energy of distance

• The energy an object has because of its motion

• the energy of molecular attraction

• the average energy in matter due to the motion of the molecules

Use the rule of conduction to answer the question. If a water bottle is put in a bucket of ice water, energy will move

• from the water bottle to the ice

• from the ice to the water bucket

• nowhere

Which process causes wet clothes on a clothes line to dry?

• Boiling

• Evaporation

• Condensation

• Freezing

As water turns into ice, the molecules in the water

• Move farther apart energy

• Move closer together

• Lose kinetic energy

• Move farther apart and lose kinetic energy

For ice to melt into water energy must be

• Added

• Taken away

• Keep the same

For matter to sublimate, energy must

• be added

• taken away

• kept the same

When matter goes through deposition, molecules

• gain energy

• get further apart

• get closer together

• lose attraction for each other

• all of the above

Liquid evaporates because molecules

• Lose energy, lose attraction for each other, and move farther apart

• Gain energy, lose attraction for each other, and move farther apart

• Lose energy, gain attraction for each other, and move closer together

• Gain energy, gain attraction for each other, and move closer together

Which effects the rate of evaporation?

• Temperature - how hot/cold the liquid is

• Movement of air - how much air is moving over the liquid

• Surface Area of liquid - how of the liquid is exposed to the air

• All of the above
