Question

During an office party, an office worker claims that a can of cold beer on his table warmed up to 20oC by picking up energy from the surrounding air, which is 25oC. Is there any truth to his claim? Explain.

Answer 1

Yes

Step-by-step explanation:

As we know that heat transfer take place from high temperature body to low temperature body.

In the given problem ,the temperature of the air is high as compare to the temperature of can of bear ,so the heat transfer will take place from air to can of bear and at the last stage when temperature of can of bear will become to the temperature of air then heat transfer will be stop.Because temperature of the both body will become at the same and this stage is called thermal equilibrium.

So an office worker claim is correct.
