What is the definition of volume in sound?
What is the definition of volume in sound?
(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 do you mean by the term volume?
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 shape occupies or contains. Volume is often quantified numerically using the SI derived unit, the cubic metre.
What is volume used for?
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. The volume of an object is measured in cubic units such as cubic centimeters, cubic inch, cubic foot, cubic meter, etc.
Does Matter have to have volume?
Mass is the amount of matter an object has, and volume is the amount of space the matter takes up. Solids are easy to recognize. They have definite shape, mass, and volume. Liquids do not have definite shape, but they do have definite mass and volume.
Do liquids have a definite volume?
Three states of matter exist – solid, liquid, and gas. Solids have a definite shape and volume. Liquids have a definite volume, but take the shape of the container. Gases have no definite shape or volume.
Does the volume of a liquid change?
As a liquid, a substance has a fixed volume, but its shape changes to fill the shape of its container. When a liquid is heated, it turns into a gas. As a gas, a substance does not have a fixed volume or shape. Gas expands to fill the shape and volume of its container.
Does solute increase volume?
Solute almost always changes the volume of final solution.
Can you change the volume of a solid?
Like liquids, gases have no definite shape, but unlike solids and liquids, gases have no definite volume either. The change from solid to liquid usually does not significantly change the volume of a substance. No definite shape (takes the shape of its container) No definite volume.
How do you solve percent by volume?
Calculating Percent Volume/Volume (% v/v)
- A percent v/v solution is calculated by the following formula using the milliliter as the base measure of volume (v):
- % v/v = mL of solute/100 mL of solution.
- Example:
- X % = 5.0 mL HCl/100 mL of solution.
- X/100 = 5.0/100.
- 100X = 500.
- X = 5.0% % v/v.
