Simone has a mug of hot tea at a temperature of 90°C. She sets the mug on a counter in a room with an air temperature of 30°C. What is most likely to happen to the temperature of the hot tea?(1 point)
Responses
The air will transfer thermal energy into the tea, and the energy transfer will continue until the tea is at room temperature.
The air will transfer thermal energy into the tea, and the energy transfer will continue until the tea is at room temperature.
The hot tea will transfer thermal energy into the air and will continue to transfer energy until they are both 90°C.
