Why does hot air rise from pavement on a hot summer day? (1 point)

Question

• Due to convection
• Due to radiation
• Due to conduction
• Due to insulation

Answer 1

Hot air rises from pavement on a hot summer day primarily due to convection. Convection is the process by which warmer, less dense air rises while cooler, denser air sinks, creating a cycle of air movement.

Answer 2

Which option is an example of heat transfer by conduction? (1 point)
O pavement heating up in the sun
• air getting warm from a radiator
• air conditioning cooling a room
• person getting warm from an electric blanket

Answer 3

An example of heat transfer by conduction is a person getting warm from an electric blanket. In this case, heat is transferred directly through contact between the person and the blanket.

Answer 4

Is that wrong

Answer 5

No, that answer is correct. The heat transfer from an electric blanket to a person occurs through conduction, as it involves direct contact between the blanket (heated by electrical resistance) and the skin, allowing heat to transfer directly from one material to another.

If you have any further questions or need clarification, feel free to ask!

Answer 6

It's wrong

Answer 7

I apologize for any confusion. Let’s clarify the examples provided:

• Pavement heating up in the sun: This is primarily through radiation.
• Air getting warm from a radiator: This involves convection, as warm air from the radiator rises and circulates.
• Air conditioning cooling a room: This system cools the air through convection and other cooling processes.
• Person getting warm from an electric blanket: This is indeed heat transfer through conduction.

Given your statement, it seems that perhaps the context of the question or a similar example led to confusion. However, based on the definitions of heat transfer mechanisms, a person getting warm from an electric blanket is, in fact, an example of conduction.

If there's another aspect or context you would like to discuss or clarify, please let me know!
