Question 4 / 5
Byrd has a mug of coffee at a temperature of 93°C. He sets the mug on a counter in a room with an air temperature of 25°C. What is most likely to happen to the temperature of the coffee?

Select an answer

A.
The hot coffee will transfer thermal energy into the air, and the energy transfer will continue until the coffee is at room temperature.


B.
The air will transfer thermal energy into the coffee, and the energy transfer will continue until the coffee is at room temperature.


C.
The hot coffee will transfer thermal energy into the air and will continue to transfer energy until they are both 93°C.


D.
The air will transfer thermal energy into the coffee and will continue to transfer energy until they are both 93°C.

Answer 1

A.

Heat flows from the hotter object to the cooler one, so the coffee will lose thermal energy to the air until they reach the same temperature (in practice, the coffee cools to room temperature).
