Analysis of a heating curve.
Heating and cooling curve graph.
Play this game to review thermodynamics.
Notice that the temperature stays the same during the state change freezing and this is the melting point.
Solid ice is heated and the temperature increases until the normal freezing melting point of zero degrees celsius is reached.
In this video i will explain the concept of heating and cooling curves as they applies to water and ethanol.
We look at what happens.
Find my revision workbooks here.
Looking from left to right on the graph there are five distinct parts to the heating curve.
Heating curve of water the phase transitions of water.
Linked to the particles topic showing heating cooling curves for substances.
Https www freesciencelessons co uk workbooks in this video we look at heating and cooling curves.
Imagine that you have a block of ice that is at a temperature of 30 c well below its melting point the ice is in a closed container.
As heat is steadily added to the ice block the water molecules will begin to vibrate faster and faster as they absorb kinetic energy.
Practice plotting line graphs from data.
Heating curves show how the temperature changes as a substance is heated up.
Describe the substance between letters a and b.
The sloped areas of the graph represent a.
Cooling curves are the opposite.
A heating or cooling curve is a simple line graph that shows the phase changes a given substance undergoes with increasing or decreasing temperature.
Just like heating curves cooling curves have horizontal flat parts where the state changes from gas to liquid or from liquid to solid.
They show how the temperature changes as a substance is cooled down.
