Final answer:
Capacity generally refers to the quantity that can be stored, either in terms of the volume of a container for liquids measured in liters and milliliters, or the amount of electrical charge a capacitor can hold, which depends on the applied voltage and physical characteristics.
Step-by-step explanation:
Understanding Capacity-
Capacity refers to various concepts depending on the context in which it is used. In a physical sense, capacity is the quantity that can be stored within a container or system. For example, in terms of metric units of capacity, we measure the volume of liquids a container can hold in liters (L) and milliliters (mL), with 1 milliliter being a thousandth of a liter. Additionally, in an electrical context, capacity can describe the amount of charge Q a capacitor can store, which is influenced by the voltage applied to it along with the capacitor's physical characteristics such as size and geometry. Furthermore, in psychology, capacity often refers to aspects of human memory, such as the ability to encode, store, and retrieve information, which varies from person to person.
In terms of answering the question provided, 'capacity' as a word most accurately aligns with 'The quantity that can be stored'. The other options provided do not reflect the standard definitions of capacity within the given contexts.
