1) Water is not used to control the fire involving electrical equipment because it is a good conductor of electricity. The person using it can get a shock. 2) LPG is a better domestic fuel than wood because -It does not give out smoke. -It has high heat content. -It does not leave ash behind. -It is easily available. 3) Paper by itself catches fire easily because it is a highly combustible substance. But when it is wrapped on aluminium, it does not burn because aluminium is a good conductor of heat and it takes the heat from paper.
