Time Zones
Usually kilograms are used for larger quantities (like, for purchasing flour), grams for smaller quantities (like, for measuring flour for a recipie).
Because.... There are two types of physical quantities. Fundamental and derived. Fundamental units cannot be derived from any of the two types of units while derived units can be derived from these two types of units. It's important to be clearly defined as there are so many indices of the base number. And no one can derive the units if they aren't properly defined
Yes it does. Because it means mole per liter and both of these units are clearly defined.
The fundamental units are those of the SI system - The unit of Temperature, Kelvin; of Time, the second; of Mass, Kilogram; of brightness, the Candela; of physical quantity, the Mole; and of electrical current, the Ampere. With these units, all fundamental quantities may be described.Comment SI doesn't use the term, 'fundamental'. Those units listed above are termed 'base' units.
Individual atoms are measures as units. Just count them up.If you want to know how many atoms are in a given sample, we use the mole as a way to count them.One mole is 6.02x1023 units. So if you have 2 moles of helium, you have 12.04x1023 atoms of helium.
The units will vary, depending on what you want to measure.
to know what is the measure
Since there are no units it is likely to be a count or a ratio.Since there are no units it is likely to be a count or a ratio.Since there are no units it is likely to be a count or a ratio.Since there are no units it is likely to be a count or a ratio.
# Units allows use to compare quatities that are not in the same space, place or time # units also indicates the physics quantities measured or been measure as each quantities has particlar units
In mathematics, two quantities are said to be in units agreement if they have the same units of measure. For example, if two quantities are both measured in meters, then they are in units agreement. If one quantity is measured in meters and the other is measured in centimeters, then they are not in units agreement.
Area is a measure of square units.
we answer quantities precisely by using measuring tools like rulers, and meter sticks :)
Generally liquid is measured in units of volume such as litres or gallons. In large quantities liquids can be measure in units of mass such as tons (of oil for instance)
In chemistry the need for standards when measuring quantities are in place for accurate measurement that is recognized worldwide. This way, no matter what language or units of measure people use, they will always understand there standards.
Count them.
Write about 10 instruments which are used to measure different physical quantities i.e. - mass, volume, time and temperature
