Heat energy lost due to friction is a source of ___________.?

Question

A. decreased entropy

B. mechanical energy

C. increased entropy

D. electrical energy

Answer 1

D. electrical energy

Answer 2

C

Answer 3

well, entropy may change, but the energy is due to mechanical energy.

Answer 4

C.

If I remember correctly, the reasoning goes thus:  heat loss to the environment is an equalisation, entropy is a measure of a systems "closeness" to total energy equilibrium.  So any equalisation of energy is an increase in entropy.

Been a long time since I done any physics, though.

Answer 5

It's definitely [C].
