Test: High School Chemistry

1.

Heating curves are used to graph the change in temperature as heat is added to a system. A solid system is heated until it is converted to a gas, and the heating curve is graphed. Why does the heating curve have two horizontal plateaus?

Heat does not increase during a phase change

These are times in the experiment when the scientists stopped heating the substance

This is a scientific error that has been created in the heating curve

Temperature does not increase during a phase change

The plateaus show when the substance is getting warmer
