Question

9. An iron ball at 40°C is dropped in a mug containing water at 40°C
The heat will
(a) flow from iron ball to water.
tbl not flow from fron ball to water or from water to iron ball.
(c) flow from water to iron ball.
(d) increase the temperature of both
end​

Answer 1

Answer:

Explanation:

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.
