Abstract

If some ice cubes from a refrigerator are put in a beaker of water and the mixture stirred, the temperature will be 0°C. If the beaker is now put on a tripod and heated very gently with a bunsen burner it will be found that the temperature remains at 0°C until all the ice has melted. The temperature of the water then begins to rise and goes on rising until it reaches 100°C. Heat energy is still being supplied to the beaker from the bunsen burner but the temperature remains steady at 100°C (Fig. 12.1). What is happening to the heat energy being supplied by the bunsen burner when the temperature remains at 100°C?
