Final answer:
The influence of volume decreases cost per unit, defining the concept of economies of scale, where increased production volume leads to more efficient production and lower average costs per unit.
Step-by-step explanation:
The influence of volume on manufacturing can be significant. When the question asks about the influence of volume, the correct answer is that it decreases cost per unit. This concept is related to what is known as economies of scale. As a business increases the volume of production, the cost per unit tends to go down, thereby making the production process more efficient. For example, a larger factory can produce goods at a lower average cost than a smaller factory, thanks to the spreading out of fixed costs over a larger number of units and often more efficient use of resources and personnel.
When a large amount of energy is added to or extracted from a system, it can cause either an increase or a decrease in the volume of a gas, which accordingly affects the gas's pressure. Additionally, in the context of gas and fluid dynamics, changes in volume can affect properties such as the speed of sound and flow rate. Therefore, understanding how volume influences various factors is essential in the fields of physics and engineering as well as business and economics.
