Which symbols represents a unit of volume

The volume of a solid is measured in cubic units. Log in. Units of Measure. Study now. See Answer. Best Answer. Study guides. Math and Arithmetic 20 cards. What is a variable.

How many meters are in 15 micrometers. How do you explain about the guidelines used for designing procedures. How many miles equals a km. Math and Arithmetic 21 cards. Convert miles per hour to feet per second.

What is the metric system prefix for the quantity 0. A car traveling 70 miles per hour is 20 miles behind a truck traveling 50 miles per hour how long will it take the car to overtake the truck.

Convert this number to scientific notation Kiteboarding 2 cards. What size kite do you use in 15 knots of wind. When was kiteboarding invented. For example, the maximum takeoff weight of a Boeing ER airliner is , kilograms, which can also be written as 2. The mass of the average mosquito is about 0. Units , such as liters, pounds, and centimeters, are standards of comparison for measurements.

When we buy a 2-liter bottle of a soft drink, we expect that the volume of the drink was measured, so it is two times larger than the volume that everyone agrees to be 1 liter. The meat used to prepare a 0.

Without units, a number can be meaningless, confusing, or possibly life threatening. Not only will this be confusing to the medical professional giving the dose, but the consequences can be dire: mg given three times per day can be effective as an anticonvulsant, but a single dose of g is more than 10 times the lethal amount.

We usually report the results of scientific measurements in SI units, an updated version of the metric system, using the units listed in Table 1. Other units can be derived from these base units. Sometimes we use units that are fractions or multiples of a base unit. Ice cream is sold in quarts a familiar, non-SI base unit , pints 0.

We also use fractions or multiples of units in the SI system, but these fractions or multiples are always powers of Fractional or multiple SI units are named using a prefix and the name of the base unit.

The prefixes used and the powers to which 10 are raised are listed in Table 2. The initial units of the metric system, which eventually evolved into the SI system, were established in France during the French Revolution. The original standards for the meter and the kilogram were adopted there in and eventually by other countries.

This section introduces four of the SI base units commonly used in chemistry. Other SI units will be introduced in subsequent chapters. The standard unit of length in both the SI and original metric systems is the meter m. A meter is about 3 inches longer than a yard Figure 1 ; one meter is about Figure 1. The relative lengths of 1 m, 1 yd, 1 cm, and 1 in. Figure 2.

The standard unit of mass in the SI system is the kilogram kg. A kilogram was originally defined as the mass of a liter of water a cube of water with an edge length of exactly 0. It is now defined by a certain cylinder of platinum-iridium alloy, which is kept in France Figure 2. Any object with the same mass as this cylinder is said to have a mass of 1 kilogram. One kilogram is about 2. Temperature is an intensive property. 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 m 3 , which is a derived unit. Physical Measurement Laboratory. Weights and Measures. Weight is a measure of the force of attraction of the earth acting on an object.

The weight of an object is not constant. Mass is a more fundamental quantity than weight. There is no English equivalent to the verb weigh that can be used to describe what happens when the mass of an object is measured.

You are therefore likely to encounter the terms weigh and weight for operations and quantities that are more accurately associated with the term mass. The seven base units for the SI system are given below. The units of every measurement in the SI system must be derived from one or more of the seven base units.

Some of the common derived SI units used in chemistry are given below. Strict adherence to SI units would require changing directions such as "add mL of water to a 1-L beaker" to "add 0. Some of these non-SI units are given below. The record for the Kentucky Derby is held by Secretariat, who ran the 10 furlongs in 1 minute, Calculate his average speed in miles per hour.
