the liquid state to the gaseous state. This transformation appears‚ when water is heated. The temperature of the water keeps increasing‚ until it has reached its boiling point at 100oC‚ where it remains until the heater gets turned off. If the water is still getting heated‚ it absorbs thermal energy‚ which turns the water into water vapour (steam) because of the separation of the molecules.

Self Heating Food and Drink Cans Heater meals – originally developed for military use – are ready-made self-heating meal packs. They can be heated in many ways – by pressing a button on the packaging‚ unwrapping and shaking the pack‚ or pouring the contents of one bag into another and waiting for a few minutes – all of which use exothermic chemical reactions. These meals can be used to motivate students to study such reactions relatively safely and without the use of a burner. Plus there is the
