Why does hot air rise from pavement on a hot summer day?

Answer 1

Hot air rises from pavement on a hot summer day due to a process called convection. When sunlight shines on the pavement, it heats up the surface. As a result, the air molecules in contact with the pavement gain energy and start moving faster, causing them to spread out and become less dense. Since hot air is less dense than cold air, it becomes buoyant and rises upwards. This creates a movement of air, leading to the rising of the hot air from the pavement.

Answer 2

Which investigation shows the transfer of heat energy in the absence of matter?

Using particles in space colliding to investigate conduction

Using electromagnetic waves to investigate radiation

Using a current through fluid to investigate radiation

Using particle movement through a solid to investigate conduction

Answer 3

Using electromagnetic waves to investigate radiation shows the transfer of heat energy in the absence of matter.

Answer 4

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?

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 will continue to transfer energy until they are both 90°C.

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

Answer 5

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