Quiz 4 Review P.C

What color is liquid oxygen?

• Yellow
• Clear
• Pale blue
• Green

If the Titan lake froze, how would the change in kinetic energy affect the speed of the molecules found in the lake?

• The kinetic energy would decrease. The molecules would move slower.
• There would be no change in kinetic energy. The molecules would move at the same speed.
• The kinetic energy would increase. The molecules would move faster.

If the Titan lake evaporated, how would the change in kinetic energy affect the speed of the molecules found in the lake?

• There would be no change in kinetic energy. The molecules would move at the same speed.
• The kinetic energy would increase. The molecules would move faster.
• The kinetic energy would decrease. The molecules would move slower.

What happened to the lake on Titan?

• The lake on Titan froze
• There was no lake on Titan
• It moved to another location on Titan
• The lake on Titan evaporated

What is freedom of movement?

• the way molecules in a substance move around relative to each other
• the energy that an object has because it is moving
• a group of atoms joined together in a particular way
• a pull between two molecules that is always the same for a substance

Transferring energy to a substance increases the kinetic energy of that substance’s

molecules. Transferring energy from a substance decreases the kinetic energy of that

substance’s molecules.

• True

• False

When energy is transferred to or from a substance, it can change the molecules’ freedom of

movement.

• True

• False

You should always read every part of a question and the answers.

• False

• True
