Practice Physical Property in Chemistry
Use these practice problems to test your method after reviewing the concept explanation and worked examples.
Quick Recap
A characteristic of matter that can be observed or measured without changing the substance's chemical identity, including properties such as color, density, melting point, boiling point, hardness, and state.
Properties you can detect just by looking, touching, or measuring — without turning the substance into something else.

Example 1
easyTrue or false: hardness (resistance to scratching) is a physical property.
Example 2
easyIs 'malleability' (can be hammered into sheets) physical or chemical?
Example 3
hardA student must separate iron filings, salt, and sand. Which physical property does each separation step use?
Example 4
mediumIs viscosity (resistance to flow) a physical or chemical property, and how would you measure it without a reaction?
Example 5
easyA block of wood has a mass of g and a volume of . Find its density.
Example 6
easyIs density a physical or chemical property?
Example 7
mediumA student finds that a sample of liquid has a density of , a boiling point of , and is clear and colorless. What is the most likely liquid?
Example 8
mediumClassify each as physical or chemical property: (a) milk turns sour, (b) salt dissolves in water, (c) rubber stretches, (d) silver tarnishes in air.
Example 9
mediumState whether 'state of matter at room temperature' (solid, liquid, or gas) is a physical or chemical property.
Example 10
mediumClassify each: (a) flammability, (b) hardness, (c) odor, (d) reactivity with water.
Example 11
mediumMercury has density . Find the mass of mercury that fills a container.
Example 12
mediumWhy is 'boiling point' more useful than 'color' for identifying a clear, colorless liquid?
Example 13
easyName two physical properties of gold.
Example 14
mediumA liquid X has boiling point and a strong sweet smell. Liquid Y has boiling point and no smell. Which physical property best separates a mixture of X and Y?
Example 15
mediumA student lists 'rusts easily' as a physical property of iron. Correct the student and explain.
Example 16
easyIs electrical conductivity (ability to carry current) a physical property?
Example 17
challengeTwo clear liquids look identical. Without causing any reaction, name three physical properties you could measure to tell them apart, and explain why these stay physical.
Example 18
mediumIs 'tarnishes when exposed to air' a physical or chemical property, and how does it differ from 'shiny'?
Example 19
mediumLead has density . What volume does of lead occupy?
Example 20
mediumA piece of silver has mass . Find its density and compare to the listed value of .
