Removing Heat

Question 1

Explain the process of freezing/solidification.

Answer 1

As a liquid cools, energy is lost from its particles and they move more slowly than before while moving closer together. If enough heat is removed, the particles will end up just vibrating on the spot in closely packed positions. Bonds strengthen and this locks them into their position to form a solid of definite shape and size.

Question 2

Explain the process of condensation.

Answer 2

As a gas is cooled, it’s particles slow down. When they have slowed enough, the individual particles begin to attract each other and form bonds that will tie their movement to the other particles in the substance. They now act as a group, forming droplets of liquid.

Question 3

What is deposition?

Answer 3

When a substances changes directly from a gas to a solid without going through a liquid state.

Question 4

What temperature is absolute zero?

Answer 4

-273 c

Question 5

What happens if heat is removed from substances?

Answer 5

Gases will condense into liquid and liquids will freeze/solidify into solids.
