The precautions that must be taken when heating alcohol are that alcohol must not be heated directly. When heating alcohol, it must always be placed in a beaker of water.
Explanation:
Alcohol on burning changes into carbon dioxide and water. The release of carbon dioxide on heating is not good and therefore alcohol must not be heated directly.
When alcohol is heated using a beaker of water, it will evaporate slowly giving alcohol vapour. The heating of alcohol in this way is a physical change whereas when alcohol is heated directly, the change is a chemical change.
