Question

question 1 (1 point)
heat can be added to or removed from substances. when a liquid substance such as water gains heat energy, which of the following can happen?
o a the liquid will remain in liquid state, no matter how much heat is gained
o b the liquid may become a solid
o c the liquid may change states, depending on the amount of heat gained
o d the liquid will always change state and become a gas

Explanation:

When heat is added to a liquid like water, its state can change. If a small amount of heat is added, it may stay liquid. But if enough heat (reaching the boiling point for water) is added, it turns to gas (vaporizes). So the state change depends on heat amount. Option a is wrong as enough heat changes state. Option b is wrong as cooling (removing heat) makes liquid to solid. Option d is wrong as “always” is incorrect - depends on heat quantity.

Answer:

c. The liquid may change states, depending on the amount of heat gained
