Question

PLS HELP!!!
A piece of copper at 10 °C is dropped into a glass of water at 35 °C. Which statement is correct?
A) Heat will flow from the copper to the water in the glass until both reach the same temperature.
B) Heat will flow from the water in the glass to the copper until both reach the same temperature.
C) The final temperature of the water in the glass and the copper will be 10 °C.
The final temperature of the water in the glass and the copper will be 35 °C.
D) The final temperature of the water in the glass and the copper will be 35 °C.

Answer 1

The answer is B) heat will flow from the water to the copper until they both reach the same temperature

Answer 2

Answer:

Heat will flow from the water in the glass to the copper until both reach the same temperature.

Explanation:

If we consider a perfectly thermal insulation in the system with glass of water at higher temperature and piece of copper at lower temperature, then when the both come in contact with each other water will lose some heat and copper will gain that heat from water. The process will continue untill both reach the same temperature. One they will reach to same temperature we will not observe any heat change or temperature change between the two.

Heat change is a function of temperature difference.
