Matter is anything that occupies space and has mass.
What are the three states of matter?
The three states of matter are solid, liquid, and gas.
What are the physical properties of matter?
Physical properties of matter include color, shape, size, density, and texture.
What is the difference between a physical and a chemical property?
Physical properties can be observed without changing the substance, while chemical properties can only be observed by changing the substance.
What is the difference between a pure substance and a mixture?
A pure substance has a fixed composition and properties, while a mixture is a combination of two or more substances that can be separated by physical means.
What is an element?
An element is a pure substance that cannot be broken down into simpler substances by chemical means.
What is a compound?
A compound is a pure substance made up of two or more elements chemically combined in a fixed ratio.
What is density?
Density is the amount of mass per unit volume of a substance.
What is a physical change?
A physical change is a change in which the substance does not change its identity, but only its physical properties.
What is a chemical change?
A chemical change is a change in which a new substance with new properties is formed.
What is the law of conservation of mass?
The law of conservation of mass states that mass is neither created nor destroyed in a chemical reaction, but is conserved.
What is a physical property of water?
A physical property of water is its boiling point of 100 degrees Celsius.
What is a chemical property of iron?
A chemical property of iron is its ability to rust when exposed to oxygen and moisture.
What is the difference between a homogeneous and a heterogeneous mixture?
A homogeneous mixture is uniform throughout, while a heterogeneous mixture has different components that can be seen.
What is the boiling point of ethanol?
The boiling point of ethanol is 78.4 degrees Celsius.
What is the melting point of gold?
The melting point of gold is 1,064 degrees Celsius.
