Question

18. An iron ball at 40 degree celsius is
dropped in a mug containing water at 60
degree celsius. the heat will
(1 Point)
flow from iron ball to water
flow from water to iron ball
not flow at all
increase the temperature of
both​

Answer 1

The temperatures of both are the same. So there would be no net heat flow from that aspect.

The heating resulting from the change in potential energy, and the heating involved in the rusting of the ball would most likely be pretty small. (Given that the ball was dropped into a mug, my guess is that the dropping was not from a great height, though I can imagine someone setting things up otherwise to be contrary.

Answer 2

flow from water to iron ball and both have increases the temperature for vary little time period
