Power is the______ of using energy or doing work.

Power is the rate at which energy is used or work is done. This means it quantifies how quickly energy is transferred or converted into a different form. For instance, when looking at electrical power, it can be measured in watts, which represent joules per second. This relationship shows that power indicates not just how much energy is being consumed, but also how fast that energy is being utilized, which is crucial in various applications, especially in the context of ice facilities where maintaining energy efficiency is key during operations.

In contrast, the other options refer to different concepts. The total amount pertains to a measure of quantity rather than a rate, volume relates to the space occupied by an object, and duration measures time without addressing the efficiency or speed of energy use.
