Question

explain why it is difficult to hold a stainless steel tumbler containing very hot tea is hand but a thermocol Cup containing the same hot tea can be held easily

Answer 1

It is bcz stainless steel is a good conductor of heat and thermocol not.

Answer 2

ANSWER:

It is difficult to hold a 'stainless steel tumbler' containing hot tea in hand because stainless steel is a good conductor of heat but a thermocol cup containing the 'same hot tea' can be easily held because thermocol is a 'poor conductor' of heat.

EXPLANATION:      

Stainless steel being the good conductor of heat make the heat reach the hand holding the tumbler with hot tea at a faster rate meanwhile thermocol is an insulator and has low thermal conductivity in it and thus hotness of the tea is being stopped by thermocol reaching the hand.
