Cooling Curves Heating curves show how the temperature changes as a substance is heated up. Cooling curves are the opposite. They show how the temperature changes as a substance is cooled down. Just like heating curves, cooling curves have horizontal flat parts where the state changes from gas to liquid, or from liquid to solid.

HEATING&COOLING CURVES A)decreases B)increases C)remains the same 39.As a liquid boils at its normal boiling point, its temperature Base your answers to questions 40 through 42 on the information below. Starting as a gas at 206°C, a sample of a substance is allowed to cool for 16 minutes. This process is represented by the cooling curve below.

Heating Curve for H20(s) to H2O(g) A 40.0 g sample of ice at -40 °C is heated until it changes to steam and is heated to 140 °C. 1.Sketch the heating curve for this change. 2.Calculate the total energy required for this transition. *Check your notes for the heating curve
