The definition of 'volume' is?

The definition of 'volume' refers to the amount of space an object or substance occupies. This concept is fundamental in various fields, including HVAC and refrigeration, as it directly relates to understanding how fluids move and how much space they will occupy in a system.

In HVAC, knowing the volume of containers, ducts, or rooms helps engineers and technicians design systems that effectively manage airflow, refrigerant distribution, and thermal loads. When calculating the volume of a space, it is essential to consider its dimensions (length, width, height) or use formulas for specific shapes (like cylinders or spheres) to ensure accurate measurements.

The other definitions provided do not align with the concept of volume. Mass refers to the quantity of matter in an object, shape pertains to the form or outline of an object, and weight is the force exerted by gravity on an object. None of these definitions accurately describe volume as the space occupied by matter.
