Match each example to a heat mechanism. Terms may be used more than once.

EXAMPLES:

A. Water is heated on a stove.
B. You feel cold near a closed window.
C. You feel cool air at your feet when you open the refrigerator.
D. A blacksmith dips red-hot steel into a bucket of water to cool it down.

HEAT MECHANISM
I. Conduction
II. Convection
III. Radiation

A = II
B = I
C = II or III?
D = III

well, congratulations, you got none right. I wont give partial credit on C, as you had one right and one wrong answer.

convection implies moving air. How does that heat water on a stove. But it might explain the air coming from the refrigerator door.

A = III

B = II
C = II
D = I

A could be radiation, but it is usually not. I have seen one infared stove top in my life which heated by radiation, all the rest were conduction from hot gases in the flame to the pot. I think the best answer for the stove top is conduction.

thanks:)

To match each example to a heat mechanism, we need to understand the concepts of conduction, convection, and radiation.

I. Conduction: Conduction occurs when heat is transferred through direct contact between the objects. It involves the transfer of heat energy from the hotter object to the cooler object. For conduction to occur, there must be physical contact between the two objects.

II. Convection: Convection is the transfer of heat energy through the movement of fluids, such as liquids or gases. It involves the circulation of a fluid due to temperature differences. Convection occurs when warmer fluid rises, carrying heat energy with it, and cooler fluid sinks, completing the cycle.

III. Radiation: Radiation is the transfer of heat energy through electromagnetic waves. Unlike conduction and convection, radiation does not require any medium or direct contact. Heat can be radiated or emitted from a hot object and absorbed or received by a cooler object.

Now let's match the examples:

A. Water is heated on a stove.
This example involves the direct contact between the stove and the pot of water, resulting in heat transfer through conduction. Therefore, A matches with I. (Conduction)

B. You feel cold near a closed window.
In this example, the cold sensation occurs because heat is being transferred away from your body to the window. The transfer happens through direct contact, so it is conduction. Therefore, B matches with I. (Conduction)

C. You feel cool air at your feet when you open the refrigerator.
When you open the refrigerator, cooler air from inside escapes, and warmer air from outside replaces it. This process involves the movement of air, making it convection. Therefore, C matches with II. (Convection)

D. A blacksmith dips red-hot steel into a bucket of water to cool it down.
This example involves the transfer of heat energy from the red-hot steel to the water without any direct contact or fluid movement. Instead, heat is being transferred through the emission and absorption of electromagnetic waves, which is radiation. Therefore, D matches with III. (Radiation)
