Question

When a physical change of a substance, like water occurs which of the following does not change?

Volume
Shape
Temperature
Composition

Answer 1

During the change from ice to water, or from water to steam, or from steam to water, or from water to ice, the TEMPERATURE doesn't change.

If you have a gram of water at 32°F (0°C) and you freeze it, you get a gram of ice at the same temp ... 32°F (0°C) . The difference is that you had to take 337 joules of heat out of that water in order to freeze it.

Answer 2

Doesn’t change the composition
