The thermal energy is transferred to the anvil and hammer.
Explanation:
In metallurgical processes, part of the thermal energy present in the hot metal is transferred to the anvil and the hammer. This is because the anvil and the hammer have different temperature than the temperature of the hot metal. With that, part of the thermal energy of the metal will be transferred to the hammer and the anvil, in an attempt to balance the thermal energy in the 3 objects.
Mitochondria are considered as the powerhouse of cell because they perform function cellular respiration process in a cell.
Cellular respiration is a process of converting the chemical energy present in nutrients into ATP which gives energy to organisms to carry out movement and physical actions.
Mitochondria performs cellular respiration process from which they can release energy present in food and nutrients.
Due to those reasons, mitochondria is called as powerhouse of cell.
