Question

Give reasons:

1.LPG is a better domestic fuel than wood.

2.paper by itself catches fire easily whereas a piece of paper wrapped around on aluminium pipe does not.

Answer 1

1) LPG us a better fuel than wood bcoz LPG doesn't produce much pollution as wood does.

2) A paper easily catches fire whereas a paper wrapped around a aluminium pipe does not because the heat we provide to paper is absorbed by the aluminium pipe, which leads to the delay in burning the paper.
