Multiple Choice
Can frozen ice transfer thermal energy to another substance? If so, under what condition does this occur?
A
Yes, but only if both substances are at .
B
Yes, if the other substance has a temperature higher than the ice ().
C
No, ice cannot transfer thermal energy to any other substance.
D
Yes, if the other substance has a temperature lower than the ice ().
Verified step by step guidance1
Understand that thermal energy transfer occurs due to a temperature difference between two substances.
Recall that heat flows spontaneously from a substance at a higher temperature to one at a lower temperature until thermal equilibrium is reached.
Identify that frozen ice has a certain temperature, typically at or below 0°C, and can transfer thermal energy if the other substance is at a different temperature.
Conclude that frozen ice will transfer thermal energy to another substance only if the other substance has a temperature lower than the ice, causing heat to flow from the ice to the other substance.
Therefore, if the other substance's temperature is higher than the ice, the ice will absorb thermal energy instead of transferring it.
