Question

A big metal ball and a small metal ball are heated till they both attain a temperature of 50 oC. They are then connected using a metal pipe at room temperature as shown in the figure. What do you expect will happen immediately on joining the 2 balls with the metal pipe?
1.Heat will flow only from the big ball towards the small ball to raise the temperature of the small ball.
2. Heat will flow only from the small ball towards the big ball to raise the temperature of the big ball.
3. No heat will flow through the metal pipe as the balls are at the same temperature.
4. Heat will flow from both the balls towards the metal pipe in opposite directions.​

Answer 1

Answer:

Option 3.

Explanation:

Heat only passes when there is a change in temperature in the objects, and in this situation, both balls have a 50-degree celsius. Therefore, option 3 is the right answer.

Hope it helps.

Have a great day.

Answer 2

Answer:

3.No heat will flow through the metal pipe as the balls are at the same temperature.
