Interpretation:
SI units for length, mass, time and temperature are to be defined.
Concept introduction:
The International System of Units or SI units is the system that consists of physical units based on kilogram, meter, second, kelvin, ampere, candela and mole together with prefixes indicating the multiplication or division by a power of ten.
Answer to Problem 4SSC
SI units for length, mass, time and temperature are Meter (m), Kilogram (kg), Second (s), Kelvin (K) respectively.
Explanation of Solution
Given information:
Length, mass, time and temperature.
Length is the measurement or the extent of a thing from one end to another. The SI unit of length is Meter, which is denoted by m. Mass is the measure of an amount of matter in any object. Its SI unit is Kilogram, which is denoted by kg. Time is what a clock reads. It is a scalar quantity. The SI unit of time is second, which is denoted by s. Temperature is a physical property of a matter. It expresses an object as hot or cold and is manifested by thermal energy. The SI unit of temperature is Kelvin, which is denoted by K.
Hence, the SI unit of length is meter (m), of mass is kilogram (kg), of time is second (s) and of temperature is Kelvin (K).
