Chapter 2: Problem 113

At room temperature, which of the following liquids has the highest density? A. orange juice B. milk C. honey D. water

Short Answer

Expert verified
Honey

Step by step solution

01

Identify the Question

The question asks which of the given liquids has the highest density at room temperature.
02

Understand Density

Density is defined as mass per unit volume and is usually measured in grams per cubic centimeter (g/cm³). A substance with higher density will have more mass in a given volume.
03

Analyze Each Liquid

Consider the typical densities of the given liquids: - Orange juice: approximately 1.04 g/cm³ - Milk: approximately 1.03 g/cm³ - Honey: approximately 1.36 g/cm³ - Water: 1.00 g/cm³
04

Compare Densities

Compare the densities of each liquid. The higher the number, the higher the density.
05

Select the Liquid with Highest Density

From the listed densities, honey has the highest density at approximately 1.36 g/cm³.

Key Concepts

These are the key concepts you need to understand to accurately answer the question.

density
Density is a fundamental property of matter that describes how much mass exists in a given volume. Essentially, density tells us how 'packed' a substance's molecules are. To calculate density, we use the formula: \( \text{Density} = \frac{\text{Mass}}{\text{Volume}} \).
It’s measured in units like grams per cubic centimeter (g/cm³). A higher density means that in the same amount of space, the substance contains more mass. Understanding density helps us compare and contrast different materials, whether they are liquids, gases, or solids.
liquid properties
Liquids are known for their ability to flow and take the shape of their container. They also have unique properties like viscosity and density that differentiate one liquid from another.
Viscosity refers to a liquid's resistance to flow, while density measures the mass per unit volume. For example, honey is more viscous and denser than water.
Understanding these properties helps us determine how liquids will behave in different situations. The interaction between molecules, their size, and how they are packed together influence these properties.
For example, honey is denser because its molecules are packed more tightly compared to those in water or milk.
mass per unit volume
Mass per unit volume is the technical way of describing density. It involves the same foundational idea: how much mass is contained within a specific volume.
This measurement is significant when comparing substances. For instance, if you had equal volumes of honey and water, honey would weigh more because it has a higher mass per unit volume.
This concept is also crucial in fields like chemistry and engineering, where understanding material properties affects everything from substance composition to building structures. It's also why objects with higher density sink in water, while those with lower density float.
measurement of density
Measuring density is a straightforward process but essential for understanding materials. You need to know the mass and the volume of the substance.
For liquids, you can use a graduated cylinder to measure the volume and a scale to measure the mass. Once you have these values, you can use the density formula.
For solids, you can measure dimensions and use mathematical formulas for volume calculation. Alternatively, for irregular objects, you can use water displacement in a graduated cylinder.
The precision in measuring mass and volume directly affects the accuracy of the density measurement, so careful measurements are crucial.
