Answer:
Heat lost by the pancake = Heat gained by butter
Explanation:
Because energy is always conserved, this process involves the loss of energy by one substance which is gained by another.
The pancakes were freshly made, so they are hot; having the required energy to melt the butter placed on them. The butter absorbs heat from the pancakes which is equal to or greater than its melting point. Thus, the butter melts due to the heat absorbed.
Therefore,
Heat lost by the pancakes = Heat gained by butter
