Answer 2

⠀⠀⠀⠀ ⠀ ⠀⠀ ⠀⠀$\boxed{\red{\underline\textbf{Answer...}}}$

⠀⠀A)...Water is not used to control fires involving electrical equipment...??

⠀⠀⠀ ⠀---✁ ⠀Water is a good conductor of electricity...So, if we use water to control fires involving electrical equipment then it can conduct electric current and cause danger electric shocks to us... Therefore, we use Carbon dioxide to control the fire involving electrical equipments...

⠀⠀⠀⠀ ⠀ ⠀⠀ ⠀⠀⠀

⠀⠀⠀B)... Why LPG is a better domestic fuel than wood...??⠀

⠀ ⠀---✁⠀ LPG burns with complete combustion because it has more calorific value by which it doesn't produce pollution...Where as wood doesn't take complete combustion and it cause pollution... That's why LPG is better domestic fuel than wood...⠀

⠀⠀⠀ ⠀C)... Paper by itself catches fire easily whereas a piece of paper wrapped around an aluminium pipe does not...??

⠀⠀⠀---✁⠀The ignition temperature of paper is less, so it catches fire easily... It does not catch fire when wrapped around aluminium pipe because aluminium absorbs the heat, so paper does not attain its ignition temperature...⠀⠀ ⠀ ⠀⠀ ⠀⠀⠀
