Answer: Option (E) is the correct answer.
Explanation:
Latent heat is defined as the amount of heat required by per mole of a substance in order to change its state.
And, latent heat of freezing (fusion) is defined as the energy required for the phase change between a liquid and a solid without any change in their temperature.
Therefore, at zero degrees Celsius energy absorbed by the ice will be consumed in breaking the bond between the water molecules held together in the solid state.
Thus, we can conclude that when a block of ice at zero degrees Celsius melts, the ice absorbs energy but does not change its temperature.
A. Radiation, conduction
B.
*Radiation will occur between the mug of hot tea and the room
*conduction will occur between the mug of hot tea and the table
C. The table as well as the surrounding air will become warmer.
This is because heat is given off from the mug of hot tea.
The lightbulb that carries more current will be the 25W bulb.
<h3>How to explain the information?</h3>
It should be noted that an electric current simply means the stream of charged particles that move through an electrical conductor or space.
In this case, it should be noted that the power is the same for both bulbs. Therefore, the 25W bulb will have the higher resistance so that it will have lower power.
Therefore, the lightbulb that carries more current will be the 25W bulb.
