Physical Properties of Matter
Have you ever wondered why snow is soft and cold while sand is rough and warm? It's because of their physical properties—the characteristics we can observe or measure without changing matter to a different substance.
Think of things you can see, smell, or touch.
Snow feels soft, while sand feels gritty—these textures are physical properties.
Pool water smells of chlorine, while bottled water has no odor.
Other physical properties of matter are states of matter: solid, liquid, and gas.
At room temperature, coal is a solid, water is a liquid, and oxygen is a gas—these are the states of matter.
The melting point is the temperature at which a substance changes from solid to liquid. Snow melts at 0°C, but sand melts at 1600°C.
Similarly, the temperature at which a liquid becomes a gas is its boiling point. Water boils at 100°C while cooking oil boils at about 300°C.
Everyday objects also have unique properties, like heat conduction—a kettle’s metal body conducts heat, but its plastic handle doesn’t.
