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.
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.
