Heating Curve

Front

What is a heating curve?

Back

A heating curve is a graph that shows the change in temperature of a substance as it is heated over time, illustrating phase changes and temperature increases.

Front

What happens between points A-B on a heating curve?

Back

Between points A-B, the temperature of the substance is increasing as it is heated.

Front

What happens between points B-C on a heating curve?

Back

Between points B-C, the substance is undergoing a phase change, specifically melting, and the temperature remains constant.

Front

What happens between points C-D on a heating curve?

Back

Between points C-D, the temperature of the substance is increasing as it transitions from a liquid to a gas.

Front

What happens between points D-E on a heating curve?

Back

Between points D-E, the substance is undergoing a phase change, specifically boiling, and the temperature remains constant.

Front

What happens between points E-F on a heating curve?

Back

Between points E-F, the temperature of the substance is increasing as it is heated further in the gas phase.

Front

What state of matter is present at point B?

Back

At point B, the substance is in the solid state.

Front

What state of matter is present at point C?

Back

At point C, the substance is in the liquid state.

Front

What state of matter is present at point D?

Back

At point D, the substance is in the gas state.

Front

What is the significance of the flat sections on a heating curve?

Back

The flat sections on a heating curve represent phase changes where the temperature remains constant while the substance changes state.
