Heating and temperature Temperature The temperature of an object is to do with how hot or cold it is, measured in degrees Celsius. Note that the WebThe rate of cooling in the two thermometers changes at different stages (liquid, transition and solid state), as shown on the graph above using the gradient of the tangent of the curve at a chosen time. Rate of cooling of paraffin wax in the alcohol thermometer: Liquid state at 4 mins. Transition phase at 21 mins. Solid state at 34mins.
WebCooling 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.
