What is matter?

Anything that has mass and takes up space.

100

What unit is commonly used to measure mass?

Grams (g).

100

What happens to the particles in matter during a physical change?

The particles rearrange but do not change their chemical composition.

100

What are the three main states of matter?

Solid, Liquid & Gas

100

What is melting?

The change from solid to liquid.

200

 Name two properties that can be used to classify matter.

Physical properties and chemical properties.

200

How do you measure the volume of a liquid?

Using a graduated cylinder.

200

Give an example of a physical change.

Examples include: Melting Ice, breaking a glass, etc.

200

Describe the arrangement of particles in a solid.

Particles are tightly packed and vibrate in place.

200

What is evaporation?

The process of a liquid turning into a gas.

300

What is the difference between a mixture and a pure substance?

A mixture contains two or more substances that are not chemically combined, while a pure substance has a uniform composition.

300

What instrument is used to measure mass?

A balance scale.

300

What is a reversible change?

A change that can be undone, like freezing and melting water.

300

What state of matter has a definite volume but no definite shape?

Liquid

300

What occurs during freezing?

A liquid changes into a solid.

400

What are the differences between elements, compounds, and mixtures?

Elements are pure substances made of only one type of atom, compounds are substances formed when two or more elements chemically combine, and mixtures are combinations of two or more substances that maintain their individual properties

400

How can you find the volume of a rectangular prism?

Volume = Length x Width x Height

400

How does temperature affect the state of matter?

Increasing temperature can cause solids to melt into liquids or liquids to evaporate into gases or the higher the temperature the faster the particles move, causing matter to change states. 

400

What characterizes a liquid in terms of particle arrangement and movement?

In a liquid, particles are closely packed but not in fixed positions, allowing them to slide past one another, which gives liquids a definite volume but no definite shape.

400

What is condensation?

The process of a gas turning into a liquid.

500

Define the term "density." How is it calculated?

Density is the mass of an object divided by its volume (Density = Mass/Volume).

500

Explain how you would find the density of an object.

Measure its mass and volume, then use the formula Density = Mass/Volume.

500

What is an example of an irreversible change?

Examples include burning wood, rust, etc.

500

How can you change a gas into a liquid?

By cooling the gas, causing condensation.

500

Describe sublimation.

The process where a solid changes directly into a gas without becoming a liquid.
