The methods of standardization or calibration employed have much in common even in the cases that appear most diverse.
The joule (/ËdÊuËl/), symbol J, is a derived unit of energy in the International System of Units. It is equal to the energy transferred (or work done) to an object when a force of one newton acts on that object in the direction of its motion through a distance of one metre (1 newton metre or NÂ·m).
To a scientist or engineer, the term energy is the potential of a system to perform work or to produce heat. Specific energy is the amount of energy per unit mass. Concentration by mass is the measurement of a quantity per unit mass. Specific energy may be thought of as the concentration of energy per unit mass.A joule is the metric, or more accurately, the International System of Units (SI) measurement of energy.o a scientist or engineer, the term energy is the potential of a system to perform work or to produce heat.
