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