FAQs on Volume vs Capacity Video Lecture - Mathematics (Maths) Class 8

1. What is the difference between volume and capacity?
Ans. Volume and capacity are related but distinct measurements. Volume refers to the amount of space occupied by an object or substance, while capacity refers to the maximum amount that an object or container can hold. In simpler terms, volume refers to the actual amount present, whereas capacity refers to the potential amount that can be held.
2. How are volume and capacity measured?
Ans. Volume and capacity are often measured using the same units, such as liters or cubic meters. The most common method is to measure the dimensions of an object or container and calculate the volume using formulas specific to the shape, such as length x width x height for a rectangular object. For irregular shapes, more complex techniques may be required. Capacity is typically determined by measuring the total volume of a container when filled to its maximum level.
3. Can volume and capacity be equal?
Ans. Yes, volume and capacity can be equal in certain cases. For example, if a container is completely filled, then the volume and capacity will be the same. However, it's important to note that volume can vary depending on the actual amount present, while capacity remains constant as it represents the maximum amount that can be held.
4. Are there any units specific to measuring volume and capacity?
Ans. While volume and capacity can be measured using various units, there are some specific units commonly used. For liquid measurements, liters (L) and milliliters (mL) are often used. Cubic meters (m³) are commonly used for measuring the volume of solids or larger quantities. In the United States, gallons are often used to measure capacity, with smaller quantities measured in fluid ounces (fl oz) or cups.
5. How does temperature affect volume and capacity?
Ans. Temperature can have a significant effect on the volume and capacity of substances, particularly liquids and gases. As temperature increases, the volume of a substance generally expands, resulting in an increase in both volume and capacity. Conversely, as temperature decreases, the volume contracts, leading to a decrease in both volume and capacity. This phenomenon is due to the thermal expansion and contraction properties of different substances.
