Which way will heat flow when ice and water are combined in a glass?

A. Heat flows from water to the ice.***
B. Heat flows from the ice to the water.
C. Heat does not flow in this situation.
D. Heat flows to the wall of the glass as condensation.
I think it's A but, I also think it's D because of the "fog" that you see in a clear glass with water and ice.

The answers are C, A, B, D, B.

BESTSWIMMEREVER! IS RIGHT 100%!!!! I PROMISEEE!

is he/she correct?!

is that true BestSwimmerEver?

ima test it...

100%!!!

You are correct that the answer is A. Heat flows from water to the ice.

When ice and water are combined in a glass, heat will flow from the water to the ice. This is because heat always flows from a higher temperature to a lower temperature. In this case, since the ice is colder than the water, heat will naturally flow from the water to the ice in an attempt to reach equilibrium.

Regarding your concern about option D, where heat flows to the wall of the glass as condensation, it is important to note that condensation occurs due to the temperature difference between the air and the cold glass surface. It is not directly related to the heat transfer between water and ice. The "fog" or condensation that you observe on the outside of a glass with water and ice is due to the moisture in the air condensing on the cold glass surface. It is a separate phenomenon from heat flow between water and ice.

So, in summary, when ice and water are combined in a glass, heat will flow from the water to the ice, while condensation occurs on the outside of the glass due to the temperature difference between the glass surface and the air.

yes, always from the hot to cold.

Technically I don't like the wording of the problem because if the water is at 0 C and the ice is at 0 C no heat flows from either to the other.
