Concept explainers
Interpretation: The property which makes density useful in identifying substances is needs to be explained.
Concept Introduction: The given volume of matter contained in a material is termed as density. That is, density is the mass per unit volume of an object:
Answer to Problem 54A
Since, density is a defining property of a substance. It is calculated by using two measurable properties. So, it is used to identifying substances.
Explanation of Solution
In a fixed volume density is the measure of mass of an object. It is calculated by dividing mass by its volume. Hence, it is a characteristic property of all the substances. It remains the same regardless of the weight of the substance present which helps to recognize a given substance.
Density of a substance is high if its volume is less than its mass.
