You notice that every time you place butter on your stack of freshly made pancakes, the butter melts. According to the law of conservation of energy, heat lost by the pancake

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
