To investigate the heating and cooling curve of water.
Chipa Thomas Maimela‘s insight:
Place some ice in a beaker.
Measure the temperature of the ice and record it.
After 1 minute measure the temperature again and record it. Repeat every minute, until at least 3 minutes after the ice has melted.
Plot a graph of time versus temperature for the heating of ice.
Heat some water in a beaker until it boils. Measure and record the temperature of the water.
Remove the water from the heat and measure the temperature every 1 minute, until the beaker is cool to touch.
Be careful when handling the beaker of hot water. Do not touch the beaker with your hands, you will burn yourself.
