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 will continue to transfer energy until they are both 90°C.
The air will transfer thermal energy into the tea and will continue to transfer energy until they are both 90°C.
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.

The air will transfer thermal energy into the tea, and the energy transfer will continue until the tea is at room temperature.
Due to convection.
The correct answer is: Due to convection.
Explanation:
On a hot summer day, the sunlight heats up the pavement, increasing its temperature. The heated pavement then transfers some of its heat to the air in direct contact with it. As the air comes into contact with the hot surface, it gets heated and expands. Since hot air is less dense than cold air, it becomes lighter and starts to rise. This phenomenon is known as convection.
To understand this, you can conduct a simple experiment. On a sunny day, place your hand close to the pavement and feel the warmth. As the heated air rises, you may also feel a flow of warm air near the ground.
Convection is an important process in meteorology. It plays a role in the formation and movement of clouds, as well as the overall circulation of the atmosphere.
