Answer 1

Answer: c

Explanation:

Answer 2

Thermosetting Plastics

Explanation:

Thermosetting Plastics

These are prepared from low molecular mass semi-fluid substances. Thermosetting plastic can withstand very high temperatures. During its curing process, the polymers link together to form a permanent chemical bond. They are poor conductors of heat and electricity and hence used in electric switches, sockets, frying pan handles, etc.

Materials used:

(a) for making uniforms of fire-men fire resistant? Melamine

(b) for giving non-stick coating on frying pans? Teflon

(c) for making handles of frying pans? Melamine

(d) for making insulation of electric wires? Bakelite

(e) for making electric switches?  Bakelite

(f) for making flexible water bottles? PET
