hen Ben holds an ice cube in his hand, which transfer of energy is taking place?
a
Heat is flowing from his hand to the ice cube.
b
Coldness is flowing from the ice cube to his hand.
c
No transfer of energy is taking place.
d
Both heat and coldness are being transferred.
The correct answer is A) Heat is flowing from his hand to the ice cube.
The correct answer is (a) Heat is flowing from Ben's hand to the ice cube.
When Ben holds an ice cube in his hand, the transfer of energy occurs due to the temperature difference between his hand and the ice cube. Energy always flows from a region of higher temperature to a region of lower temperature, which is known as heat transfer.
In this case, Ben's hand has a higher temperature than the ice cube, so the heat energy from his hand transfers to the ice cube. As a result, the ice cube absorbs the heat energy, and its temperature starts to increase, causing it to melt.
Option (b) is incorrect because "coldness" is not a type of energy. Coldness is actually the absence or reduction of heat energy.
Option (c) is also incorrect because there is indeed a transfer of energy taking place.
Option (d) is incorrect because heat and coldness are not separate entities. Heat is the transfer of thermal energy, and in this scenario, only heat energy is being transferred from Ben's hand to the ice cube.
a
Heat is flowing from his hand to the ice cube.
