👉 Burnup is a unit of energy that measures how much heat is produced or absorbed by an object during its combustion. It's often used in thermodynamics and engineering to analyze the efficiency of engines, power plants, and other sources of energy. In simple terms, it refers to the energy required to convert one unit of fuel into another. For example, if you have a car engine that burns gasoline (with a heat output of 200 kW), it will burn this gasoline in order for
