MATTER BASICS
This is anything that has mass and takes up space.
What is matter?
A substance made of only one type of atom is called this.
What is an element?
A property that can be observed or measured without changing the substance into something new is called this.
What is a physical property?
This tool is commonly used to measure the mass of an object.
What is a balance/scale?
This state of matter has a definite shape and a definite volume.
What is a solid?
This is the amount of matter in an object.
What is mass?
Two or more different elements chemically bonded together form this.
What is a compound?
Flammability is an example of this type of property.
What is a chemical property?
This tool is commonly used to measure the volume of a liquid in a chemistry lab.
What is a graduated cylinder?
This state has a definite volume but takes the shape of its container.
What is a liquid?
This describes how much space an object or substance takes up.
What is volume?
Two or more substances that are physically combined, but not chemically bonded, form this.
What is a mixture?
Color, density, melting point, and boiling point are all examples of this type of property.
What are physical properties?
Mass is commonly measured in these units.
What are grams (g) or kilograms (kg)?
This state has no definite shape and no definite volume and expands to fill its container.
What is a gas?
A basketball, a glass of water, and the air inside a balloon are all examples of this.
What is matter?
Classify each as an element, compound, or mixture: gold, water, and salt water.
Gold = element
Water = compound
Salt water = mixture
The ability of iron to react with oxygen and form rust is an example of this type of property.
What is a chemical property?
A rock has a mass of 50 g and takes up 20 mL of space. Which measurement tells you how much matter is in the rock?
50 g, the mass.
In this state, particles are packed closely together and mainly vibrate in place.
What is a solid?
A student says that light is matter because they can see it. Explain why the student is incorrect.
Light is not matter because it does not have mass or take up space.
You have a container holding iron filings and sand. You can separate the substances without creating a new substance. Is this an element, compound, or mixture? Explain.
Mixture, because the substances are physically combined and can be separated.
A student says, "If something changes color, that automatically means its color is a chemical property." Is the student correct? Explain.
No. Color itself is a physical property. A color change caused by a chemical reaction can be evidence of a chemical change, but simply observing color is a physical property.
Two identical-sized blocks are made of different materials. Block A has a mass of 50 g. Block B has a mass of 100 g. Which block contains more matter?
Block B, because it has greater mass.
Compare the particles in a solid, liquid, and gas. How are their spacing and movement different?
