Answer:
The particles that make up a substance in its liquid state have <u>more </u>kinetic energy than those of the same substance in its solid-state.

For a liquid to freeze, energy must be <u>removed from</u> the system.
Answer:
Water- 9.982 grams
toluene-8.669 grams
chloroform - 14.832 grams
Explanation:
the units of density are listed as g/mL. So for every mL of substance you have, you will have that many grams.
Water- .9982g/mL * 10 mL
As you can see, the units of "mL" cancel each other out, leaving just the gram amount of water.
