Amplify Modeling Matter Quiz 1

How can the properties of matter be classified?

• Into solid and liquid properties

• Into physical properties and chemical properties

• By their color and texture

• Based on their temperature and pressure

What is the difference between a homogeneous mixture and a heterogeneous mixture?

• A homogeneous mixture has a non-uniform composition, while a heterogeneous mixture has a uniform composition.

• A homogeneous mixture has a uniform composition throughout, while a heterogeneous mixture has a non-uniform composition.

• A homogeneous mixture is always a solid, while a heterogeneous mixture is always a liquid.

• A homogeneous mixture can be separated by physical means, while a heterogeneous mixture cannot.

What is a substance?

• A substance is matter that is made of only one kind of atom or molecule.

• A substance is a mixture of different atoms and molecules.

• A substance is a form of energy that can be measured.

• A substance is anything that has mass and takes up space.

What is an inference?

• A conclusion drawn from evidence and reasoning

• A type of observation made during an experiment

• A statement that is always true

• A guess made without any information

What is a mixture?

• A mixture is a single substance.

• A mixture is matter that is made of more than one substance.

• A mixture is a chemical reaction between two elements.

• A mixture is a solution that cannot be separated.

Why is understanding the composition of matter important in science?

• It helps in predicting how substances will behave in different situations.

• It allows scientists to create new elements.

• It is only relevant for chemistry students.

• It has no impact on scientific research.

What is an example of a pure substance?

• Water (H2O)

• Salt (NaCl)

• Air

• Sugar (C12H22O11)

What is matter?

• Matter is the stuff that things are made of.

• Matter is a type of energy.

• Matter is a scientific theory about the universe.

• Matter is a form of liquid that cannot be seen.

What is the role of observation in making inferences?

• Observation is irrelevant to making inferences.

• Observation provides the data needed to draw conclusions based on prior knowledge.

• Observation is only useful for collecting data, not for making inferences.

• Observation can lead to incorrect conclusions without prior knowledge.

Can a mixture be separated into its components?

• Yes, a mixture can be separated into its components by physical means.

• No, a mixture cannot be separated into its components.

• A mixture can only be separated by chemical means.

• A mixture can be separated only if it is homogeneous.
