How do you measure the mass and volume of alcohol if it is in a sealed container? Are there clever ways of achieving this? The weight of the container is not known.
It is important to remember these six fundamental (or 'base') units of measurement: metre (m) - unit of length. kilograms (kg) - unit of mass. second (s) - unit of time. ampere (A) - unit of ...
• A unit is a particular physical quantity, defined and adopted by convention, with which other particular quantities of the same kind are compared to express their value. • A measurement is a direct or indirect comparison of a certain quantity with an appropriate standard or unit of measurement.
Calculating mass. Mass is a measure of how much matter there is in an object, while weight is a measure of the size of the pull of gravity on the object. Key fact. Mass is the amount of...
An officially recognized method for the determination of alcohol concentrations in alcohol-water mixtures either by weight (%w/w) or volume (%v/v; ABV = alcohol by volume) is the measurement of density followed by conversion into alcohol concentration using official alcohol tables.
12 gru 2023 · The measurement of a physical quantity is called direct when the measured quantity is directly compared with the unit sample of measurement or its multiples or sub-multiples. For example, the determination of mass with a equal-arm balance (with calibration weights) or the length of a table with a graduated ruler are direct measurements.
3 paź 2023 · He formulated the equation: F = G (m 1 m 2)/r 2. Where: – F is the gravitational force between two objects, – G is the gravitational constant, – m_1 and m_2 are the masses of the two objects, – r is the distance between their centers.
