exhaust
This word carries a heavy sense of finality and total depletion. When applied to resources, it suggests a dead end where no further alternatives exist, creating a feeling of desperation or completion. It is more absolute than "use" or "spend."
When applied to human energy, it describes a state of total collapse rather than simple tiredness. It implies a void where energy once was, often associated with burnout or extreme physical exertion. In a mechanical sense, it shifts from a state of depletion to a state of expulsion, focusing on the waste products of combustion.
Countable when referring to the specific pipe or system on a vehicle. Uncountable when referring to the actual gas emitted into the air.
