What is the equation for absorbed energy?

The equation for absorbed energy is accurately represented by the relationship between the energy transferred to a system and any energy that escapes from it. Absorbed energy specifically refers to the amount of energy that remains within the system after accounting for what has been lost to the surrounding environment.

In this case, "Energy transferred" represents the total energy supplied to the system. If some of this energy is lost or escapes, it must be subtracted from the total to calculate the absorbed energy. This results in the formulation where absorbed energy equals energy transferred minus energy escaped. This is crucial in various contexts, particularly in understanding dose delivered in radiation therapy, as it directly correlates with the amount of energy that contributes to a biological effect.

Contextually, other formulations do not accurately represent the concept of absorbed energy in practical scenarios or scientific understanding. For instance, combining absorbed energy with energy released does not provide a clear picture of what energy remains in the system after losses have occurred. Hence, the formulation that accurately captures the necessary relationship of energy input versus energy lost is the most fitting explanation for absorbed energy.
