What unit is volume?
What unit is volume?
Volume is the measure of the 3-dimensional space occupied by matter, or enclosed by a surface, measured in cubic units. The SI unit of volume is the cubic meter (m3), which is a derived unit. Liter (L) is a special name for the cubic decimeter (dm3).
What is the volume of a gas?
Gas is a state of matter that has no fixed shape and no fixed volume. Gases have lower density than other states of matter, such as solids and liquids. There is a great deal of empty space between particles, which have a lot of kinetic energy.
What is the volume at NTP?
The standard pressure is 1atm or 760mmHg. The volume occupied by 0.1 mole of gas at NTP is 2.24Litres.
What is the volume of liquid?
At its most basic level, volume is simply a measure of space. When measuring the volume of a liquid, sometimes referred to as capacity, the units liters (L) and milliliters (mL) are used. Devices used for this measurement include graduated cylinders, beakers, and Erlenmeyer flasks.
What is used in meaning the volume of liquid?
Liquid volume is “the amount of space occupied by a liquid at rest or their containers”. In general, the volume of liquid can be measured by using the glass or plastic graduated cylinders or burets. It is expressed as cubic units of liquid measurements such as liters, millilitres, and so on.
Does liquid have 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.
Has definite volume and can flow?
A solid has definite volume and shape, a liquid has a definite volume but no definite shape, and a gas has neither a definite volume nor shape. The change from solid to liquid usually does not significantly change the volume of a substance.
Is liquid a fixed volume?
Liquids have a fixed volume but no fixed shape. Gases have no fixed volume and no fixed shape. Gases expand to fill the space available. They can also be compressed into a very small space.
Does liquid have more volume than solid?
In general, gases have the largest volume, then liquids, and solids are the smallest. But you may be thinking about ice. Ice is a very strange solid which is actually less dense (so takes up a bigger volume) than water! To summarise, solids USUALLY take up a smaller volume than liquids, but water-ice is weird!
What is the volume of solid?
The volume of a solid is the measure of how much space an object takes up. It is measured by the number of unit cubes it takes to fill up the solid. Counting the unit cubes in the solid, we have 30 unit cubes, so the volume is: 2 units⋅3 units⋅5 units = 30 cubic units.
Does Solid have volume?
Why does the sound travels fastest in solid and slowest in air?
Sound travels fastest through solids. This is because molecules in a solid medium are much closer together than those in a liquid or gas, allowing sound waves to travel more quickly through it. In fact, sound waves travel over 17 times faster through steel than through air.
What can sound waves not travel through?
vacuum
Can sound spread out in all directions?
Sound vibrations, then, travel outwards in all directions in waves from a sound source. As they travel outwards the energy they contain becomes dissipated and therefore the sound becomes weaker the further it is from the source. The shape of a sound wave with no obstacles in its way would be approximately spherical.
Can light travel in a vacuum?
Light travels in waves, and, like sound, can be slowed depending on what it is traveling through. Nothing can outpace light in a vacuum. However, if a region contains any matter, even dust, light can bend when it comes in contact with the particles, which results in a decrease in speed.
