Question

5. If energy is transferred from a table to a block of ice moving across the

table, which of the following statements is true?
a. The table and the ice are at thermal equilibrium.
b. The ice is cooler than the table.
c. The ice is no longer 0°C.
d. Energy is being transferred from the ice to the table.

Answer 1

When energy is transferred from a table to a block of ice moving across it, the ice heats up and melts, no longer at 0°C.

Step-by-step explanation:

When energy is transferred from a table to a block of ice moving across the table, the ice will heat up and melt due to the transfer of thermal energy. This means that the ice is no longer at 0°C and has become warmer. Therefore, statement c. The ice is no longer 0°C is true. Additionally, since energy is being transferred from the table to the ice, the ice is receiving energy and gaining heat, so statement b. The ice is cooler than the table is false. Lastly, statement d. Energy is being transferred from the ice to the table is false as well, because the energy transfer is happening from the table to the ice.
