A). Due to convection
Hot air rises from the pavement on a hot summer day primarily because of convection. When the pavement heats up from the sun, it warms the air directly above it. This warm air becomes less dense and rises, while cooler air moves in to take its place, creating a convection current.

A). Using electromagnetic waves to investigate radiation
This option shows the transfer of heat energy in the absence of matter, as radiation can occur through a vacuum (space) without the need for particles to transfer energy. Electromagnetic waves, such as infrared radiation, can carry heat energy across empty space.

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?
options:
A). The air will transfer thermal energy into the tea and will continue to transfer energy until they are both 90°C.
B). The hot tea will transfer thermal energy into the air and will continue to transfer energy until they are both 90°C.
C). The hot tea will transfer thermal energy into the air, and the energy transfer will continue until the tea is at room temperature.
D). The air will transfer thermal energy into the tea, and the energy transfer will continue until the tea is at room temperature.

C). The hot tea will transfer thermal energy into the air, and the energy transfer will continue until the tea is at room temperature.
In this scenario, heat will naturally flow from the hotter object (the tea) to the cooler surroundings (the air) until thermal equilibrium is reached. This means the tea will cool down as it transfers heat to the air, continuing until it reaches a temperature closer to that of the room.

A). person getting warm from an electric blanket
This is an example of heat transfer by conduction because heat is transferred directly through the material of the electric blanket to the person's body. The warmth is conducted from the blanket into the person's skin and body.
