Heating And Cooling Graphs That Include Changes Of State

Just like heating curves cooling curves have horizontal flat parts where the state changes from gas to liquid or from liquid to solid.

Heating and cooling graphs that include changes of state.

Summary of state changes. Notice that the temperature stays the same during the state change freezing and this is the melting point. Cooling curves are the opposite. For example liquid water turns into steam when it is heated enough and it turns into ice when it is cooled.

The diagram shows a cooling curve for salol. If a heater of known power is used such as a 60 w immersion heater that provides 60 j s the temperature of a known mass of. If a heater of known power is used such as a 60 w immersion heater that provides 60 j s the temperature of a known mass of. Plot a graph of temperature against time.

Https www freesciencelessons co uk workbooks in this video we look at heating and cooling curves. This could be diagrammed in a cooling curve that would be the reverse of the heating curve. We look at what happens. They show how the temperature changes as a substance is cooled down.

The ice could then be cooled to some point below 0 c. Substances can change state usually when they are heated or cooled. The sloped areas of the graph represent a. Heating curves show how the temperature changes as a substance is heated up.

Interpret heating and cooling graphs that include change of state reading heating and cooling curves examples and step by step solutions gcse igcse physics notes. All of the changes of state that occur between solid liquid and gas are summarized in the diagram in the figure below. Latent heat can be measured from a heating or cooling curveline graph. Latent heat can be measured from a heating or cooling curve line graph.
