Matter Study Guide

Front

What do you call something that has mass and takes up space?

Back

matter

Answer explanation

The term 'matter' refers to anything that has mass and occupies space. While 'mass' and 'volume' are related concepts, they do not encompass both properties together like 'matter' does.

Do physical changes change the type of matter?

Back

true

Answer explanation

The statement is true because physical changes, such as melting or boiling, alter the form of matter but not its chemical composition. Therefore, the type of matter remains unchanged.

Front

An example of chemical change is...

Back

baking a cake

Answer explanation

Baking a cake involves mixing ingredients and undergoing a chemical reaction when heated, resulting in a new substance. In contrast, slicing bread, breaking a pencil, and making a salad do not change the chemical composition of the materials.

The particles in which state of matter are far apart and bouncing around?

Back

gas

Answer explanation

In a gas, particles are far apart and move freely, bouncing around due to their kinetic energy. This contrasts with solids, where particles are closely packed and fixed in place.

Front

What are the states of matter?

Back

solid, liquid, and gas

Answer explanation

The states of matter are solid, liquid, and gas. Juice is not a state of matter; it is a liquid. Therefore, the correct answer is solid, liquid, and gas.

Matter that has its own shape and takes up space.

Back

solid

Answer explanation

A solid is a state of matter that has a definite shape and volume, meaning it maintains its form and occupies space. In contrast, liquids take the shape of their container, and gases have neither a fixed shape nor volume.

Milk takes the shape of its container because it is a: solid, liquid, gas

Back

liquid

Answer explanation

Milk is a liquid, which means it can flow and take the shape of its container. Unlike solids, which maintain a fixed shape, liquids adapt to the shape of the space they occupy.

Front

Matter that always fills the shape in a container, such as air.

Back

gas

Answer explanation

The correct answer is gas because it is the state of matter that fills the entire shape of its container, like air does. Solids maintain their shape, and liquids take the shape of the container but do not fill it completely.

Front

What happens when my glass of water is sitting in the sun and disappears into a gas?

Back

evaporation

Answer explanation

When a glass of water sits in the sun, it absorbs heat, causing the water molecules to gain energy and transition from liquid to gas. This process is called evaporation, which is the correct answer.

Molecules are closest together in a: Solid, Liquid, Gas, plasma

Back

Solid

Answer explanation

Molecules are closest together in a solid due to strong intermolecular forces, which keep them tightly packed. In liquids, they are less tightly packed, and in gases, they are far apart. Plasma consists of ionized gases with even more space between particles.
