States of Matter
This state of matter has a definite shape and a definite volume.
What is a solid?
This type of property can be observed without changing a substance into a new substance.
What is a physical property?
A change in the state of matter, such as melting ice, is an example of this type of change.
What is a physical change?
Matter with a uniform and unchanging composition is called this.
What is a pure substance?
This separation technique uses a barrier to separate materials based on differences in particle size.
What is filtration?
This state of matter has an indefinite shape but a definite volume.
What is a liquid?
Color, density, and boiling point are examples of this type of physical property because they do not depend on the amount of matter present.
What are intensive properties?
This type of change does not turn one substance into a new substance.
What is a physical change?
This type of substance consists of two or more different elements joined together in fixed proportions.
What is a compound?
This separation technique can produce rock candy from a sugar solution.
What is crystallization?
This state of matter has both an indefinite shape and an indefinite volume.
What is a gas?
Mass, volume, and length are examples of this type of physical property because they depend on the amount of matter present.
What are extensive properties?
Rust forming on an iron nail is an example of this type of change.
What is a chemical change?
Iron is an example of this type of pure substance because it consists of only one type of atom.
What is an element?
This technique separates parts of a mixture based on their different boiling points.
What is distillation?
This property of copper describes its ability to react with air and form a green layer.
What is a chemical property?
Burning wood is an example of this type of change.
What is a chemical change?
Orange juice containing visible chunks of pulp is an example of this type of mixture.
What is a heterogeneous mixture?
This technique separates or identifies components based on how quickly different compounds move across a material.
What is chromatography?
The ability of copper to be stretched into a wire is this type of property
What is a physical property?
Stirring cake ingredients together is an example of this type of change.
What is a physical change?
Clean air is an example of this type of mixture because its components are uniformly distributed.
What is a homogeneous mixture?
According to this law, the total mass of the reactants in a chemical change equals the total mass of the products.
What is the Law of Conservation of Mass?
