(Entry 1 of 3) 1 : the degree of loudness or the intensity of a sound also : loudness. 2 : the amount of space occupied by a three-dimensional object as measured in cubic units (such as quarts or liters) : cubic capacity — see Metric System Table, Weights and Measures Table.
What is the volume in physics?
Volume in Physics
Volume is the amount of three-dimensional space enclosed by a closed surface in terms of numerical value . For example, the space that a substance can be solid, liquid, gas, or plasma, or any space-occupying shape.
What is volume in physics for kids?
Volume refers to the amount of space the object takes up . In other words, volume is a measure of the size of an object, just like height and width are ways to describe size. If the object is hollow (in other words, empty), volume is the amount of water it can hold.
What is volume simple answer?
Volume is the quantity of three-dimensional space enclosed by a closed surface . For example, the space that a substance (solid, liquid, gas, or plasma) or 3D shape occupies or contains. Volume is often quantified numerically using the SI derived unit, the cubic metre.
What is volume Science for Kids?
The volume of an object is a measure of the amount of space occupied by that object , and is not to be confused with mass. The volume of a mountain is much larger than the volume of a rock, for instance. ... The width (or breadth) refers to the size of the object in a direction perpendicular to its length.
What is the example of volume?
Volume is the measure of the capacity that an object holds. For example, if a cup can hold 100 ml of water up to the brim , its volume is said to be 100 ml. Volume can also be defined as the amount of space occupied by a 3-dimensional object.
What is volume in math definition?
In math, volume is the amount of space in a certain 3D object . For instance, a fish tank has 3 feet in length, 1 foot in width and two feet in height. To find the volume, you multiply length times width times height, which is 3x1x2, which equals six.
What is difference between area and volume?
An area is a two-dimensional object whereas volume is a three-dimensional object . The area is a plain figure while volume is a solid figure. The area covers the outer space and volume covers the inner capacity. The area is measured in square units and volume is measured in cubic units.
How can we get the volume?
Whereas the basic formula for the area of a rectangular shape is length × width, the basic formula for volume is length × width × height.
What is difference between mass and volume?
Mass is the physical quantity that signifies the amount of the matter in the body of an object. Volume is the evaluation of how much 3-multidimensional space is occupied by the object. ... Volume is the geometric value. Mass is the measure of the amount of weight that is accommodated in an object or a matter.
How is volume used in everyday life?
One of the main ways volume is used daily is when calculating drinking amounts. Soda pop is bought in 12-ounce cans or 20-ounce bottles. At the bar someone might order a pint of beer. Mayo Clinic recommends people drink a little more than 8 cups of water a day or eight 8-ounce glasses of water, about 1.9 liters.
How do you introduce volume to students?
- Instruct your students to construct a rectangular prism with linking cubes. ...
- Next, instruct them to keep the length and width the same, but construct a prism that has a height of two cubes. ...
- Continue with three cubes for the height. ...
- Show the students a cylinder and ask them how many cubes would fit it in.
Why do we need to know volume?
Finding the volume of an object can help us to determine the amount required to fill that object , like the amount of water needed to fill a bottle, an aquarium or a water tank. ... Here, for example, the volume of the cuboid or rectangular prism, with unit cubes has been determined in cubic units.
What is a fact about volume?
Volume is the amount of space occupied by an object or a material . Volume is said to be a derived unit, since the volume of an object can be known from other measurements. In order to find the volume of a rectangular box, for example, one only needs to know the length, width, and depth of the box.
What is the formula for volume in science?
Calculate the volume of the substance by dividing the mass of the substance by the density (volume = mass/density) .
What is volume in science matter?
Matter has two fundamental properties: volume and mass. Volume simply refers to the space an object takes up . Depending on the physical state of an object, there are a couple ways to measure volume. ... This measure would be reported in liters. Again, a liter is just a measure of how much space a liquid takes up.
