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.
Properties you can detect just by looking, touching, or measuring — without turning the substance into something else.
Example 1
easyDefine a physical property and list four examples.
Example 2
mediumA student measures the following properties of an unknown metal: density = 8.96\,\text{g/cm}^3, melting point = 1085°\text{C}, color is reddish-orange, and it conducts electricity. Are these physical or chemical properties? Use them to identify the metal.
Example 3
mediumClassify each property as physical or chemical: (a) iron has a density of 7.87\,\text{g/cm}^3, (b) sodium reacts vigorously with water, (c) diamond is the hardest natural substance, (d) gasoline is flammable.
Example 4
hardEthanol has a boiling point of 78.4°\text{C} and water boils at 100°\text{C}. Explain how this difference in physical properties can be used to separate a mixture of ethanol and water.
