Heating and Cooling Curves represent amount of heat (q) absorbed or released by a substance during phase changes.

Heating & Cooling Curves

Concept #1: Introduction to Heating and Cooling Curves

Concept #2: Temperature Changes vs Phase Changes

Example #1: Identify line segment on the diagram where specific heat of liquid water is used to calculate energy flow.

Concept #3: Calculations with Heating & Cooling Curves

Example #2: How much total energy (J) is required to convert 55.8 g of ice at -5 ºC to a gas at 100 ºC?

Practice: How much energy (kJ) is required to convert a 76.4 g acetone (MM = 58.08 g/mol) as a liquid at -30°C to a solid at -115.0°C?

Practice: If 53.2kJ of heat are added to a 15.5g ice cube at - 5.00 oC, what will be the resulting state and temperature of the substance?
