Example:
Imagine trying to cook a meal using only the heat from a single candle. Just as you need to find a way to concentrate and utilize the candle's heat effectively to cook your meal, a heat engine works by converting scattered thermal energy into focused mechanical energy. In both scenarios, the key challenge is transforming a diffuse source of energy into a concentrated form that can perform work—whether that's making dinner or powering a vehicle.
