Chapter 3.2, Problem 26LC

Interpretation Introduction

Interpretation: The name and symbol of the SI units for mass, length, volume, and temperature are to be identified.

Concept introduction: The SI unit is the International System of Units used to address the metric system globally accepted standard measurements.

Answer to Problem 26LC

Physical quantity	Symbol for quantity	SI unit name	Symbol for SI unit
mass	$m$	kilogram	$\text{kg}$
length	$l$	meter	$\text{m}$
volume	$V$	cubic meter	${\text{m}}^3$
temperature	$T$	kelvin	$\text{K}$

Explanation of Solution

The SI unit is the International System of Units used to address the metric system globally accepted standard measurements.

The abbreviation of SI is Le System International d’ Unites. The physical quantities such as mass, length, temperature, current, time, amount of substance, and intensity are the seven base units of the SI system.

Mass: Mass is a measurement used to quantify an object in comparison to that standard mass of 1 kilogram. The kilogram is the SI unit of mass.

Length: One of the vital properties of the materials is length. The meter is the SI unit of length. The symbol is $\text{m}$ .

Volume: Any sample of matter takes up space, which is known as volume. The cubic meter is the SI unit of volume. The symbol is ${\text{m}}^3$ . But usually, volume is expressed in liter ( $\text{L}$ ), non-SI unit.

Temperature: A measure of an object's heat or cold is its temperature. Kelvin is the SI unit of temperature. The symbol is $\text{K}$ .
