The difference between the accepted value and the experimental value


Experimental Value

A quantitive value measured during an experiment


Gram

A metric mass unit equal to the mass of 1 cm3 of water at 4 C


International System of Units

The revised version of the metric system, adopted by international agreement in 1960


Joule

The SI unit of energy: 4.184 J equal one calorie


Kelvin scale

The temperature scale in which the freezing point of water is 273K and the boiling point is 373K; 0K is absolute zero


Kilogram

The mass of 1 L of water at 4 C; it is the base unit of mass in SI


Liter
