what are physical properties

Physical properties of matter can be measured and observed. Physical properties can be detected with your senses . For example, they may be things that you can see, hear, smell, feel, or even taste. Q: What are some differences between snow and sand? Which senses could you use to find out the differences? A: You can see that snow and sand have a different color . You can also feel that snow is softer than sand. Both color and hardness are physical properties of matter . You can notice that ice will melt at room temperature. Sand will remain a solid at room temperature.

examples of physical properties

Physical properties include the state of matter. We know these states as solid, liquid, or gas. Properties can also include color and odor. For example, oxygen is a gas. It is a major part of the air we breathe. It is colorless and odorless. Chlorine is also a gas. In contrast to oxygen, chlorine is greenish in color. It has a strong, sharp odor. Have you ever smelled cleaning products used around your home? If so, you have probably smelled chlorine. Another place you might smell chlorine is at a public swimming pool. The chlorine is used to kill bacteria that may grow in the water. Other physical properties include hardness, freezing, and boiling points. Some substances have the ability to dissolve in other substances. Some substances cannot be dissolved. For example, salt easily dissolves in water. Oil does not dissolve in water. Some substances may have the ability to conduct heat or electricity. Some substances resist the flow of electricity and heat. These properties are demonstrated in Figure 1.1. Can you think of other physical properties? The video below compares physical properties.
