question 10 of 10
how does the temperature of water change when it is placed then begins to freeze?
a. it increases first and then decreases.
b. it decreases first and then remains constant.
c. it increases first and then remains constant.
d. it decreases first and then increases.

Explanation:

When water is placed in a cold - environment and begins to freeze, its temperature first decreases until it reaches the freezing point (0°C at standard atmospheric pressure). Once it starts to freeze, the temperature remains constant during the phase - change process as the heat energy is used for the transition from liquid to solid rather than changing the temperature.

Answer:

B. It decreases first and then remains constant
