Measure the temperature of the ice and record it.
Heating and cooling curve for water.
For water this temperature is 100 c because the boiling point for water is 100 c.
Looking from left to right on the graph there are five distinct parts to the heating curve.
After 1 minute measure the temperature again and record it.
Solid ice is heated and the temperature increases until the normal freezing melting point of zero degrees celsius is reached.
Apparatus beakers ice bunsen burner thermometer water chipa thomas maimela s insight.
See on scoop it physical sciences break 1 0 aim to investigate the heating and cooling curve of water.
Changes of state can be investigated by measuring the temperature as a substance changes state.
To investigate the heating and cooling curve of water.
The sample is initially ice at 1 atm and 23 c.
Place some ice in a beaker.
After 1 minute measure the temperature again and record it.
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.
Method place some ice in a beaker.
Heating curve of water the phase transitions of water.
As heat is steadily added to the ice block the water molecules will begin to vibrate faster and faster as they absorb kinetic energy.
Analysis of a heating curve.
Figure pageindex 3 shows a heating curve a plot of temperature versus heating time for a 75 g sample of water.
A heating or cooling curve is a simple line graph that shows the phase changes a given substance undergoes with increasing or decreasing temperature.
As heat is added the temperature of the ice increases linearly with time.
Different substances have different melting points and boiling points but the shapes of their heating curves are very similar.
The sloped areas of the graph represent a.
For example this is the heating curve for iron a metal that melts at 1538 c and boils at 2861 c.
