Concept explainers
(a)
Interpretation:
The given volume equivalent is to be stated.
Concept introduction:
Unit conversion is a method to convert a unit into another unit which has the same dimension. The unit conversion can be performed by dividing or multiplying a unit by a specific number. In some cases such as in the conversion of temperature units, a specific number is to be added.
