Chemistry Flashcard

Front

What is chemistry the study of?

Back

Animals

Answer explanation

Chemistry is the study of matter, which includes everything that has mass and takes up space. While animals are made of matter, the correct answer is actually 'Matter', not 'Animals'. Therefore, the correct choice is 'Matter'.

Front

What is a more scientific term for “stuff”?

Back

Matter

Answer explanation

The term "matter" refers to anything that has mass and occupies space, making it a more scientific term for "stuff". Atoms, particles, and molecules are components of matter, but "matter" encompasses all physical substances.

Front

Which of the following is NOT an example of matter? Water, Air, Sound, A table

Back

Sound

Answer explanation

Sound is NOT matter because it is a form of energy that travels through air or other mediums as vibrations, while water, air, and a table are all composed of particles and have mass.

Front

What are the smallest parts that make up matter?

Back

Atoms and molecules

Answer explanation

The smallest parts that make up matter are atoms and molecules. Atoms are the basic units of matter, while molecules are formed when two or more atoms bond together. Cells, particles of light, and states of matter are larger structures.

Front

What are the three common states of matter on Earth?

Back

Solid, liquid, gas

Answer explanation

The three common states of matter on Earth are solid, liquid, and gas. These states describe the physical forms substances can take, distinguishing them based on their shape and volume.

Front

Which state of matter has molecules that vibrate but do not move past each other?

Back

Solid

Answer explanation

In solids, molecules are closely packed and can only vibrate in place without moving past each other. This is in contrast to liquids and gases, where molecules can move freely.

Front

What allows liquids to change shape?

Back

Molecules can move past each other.

Answer explanation

Liquids can change shape because their molecules can move past each other, allowing them to flow. This is in contrast to solids, where molecules are fixed in place.

Front

Why do gases fill any container they are in?

Back

Their molecules are far apart and move freely.

Answer explanation

Gases fill any container because their molecules are far apart and move freely. This allows them to expand and occupy the entire volume of the container, unlike solids or liquids where molecules are closer together.

Front

What is an atom?

Back

The basic building block of all matter

Answer explanation

An atom is the basic building block of all matter, consisting of protons, neutrons, and electrons. It is not a molecule, nor is it limited to solid or liquid states, making 'the basic building block of all matter' the correct choice.

Front

What is a molecule?

Back

A group of two or more atoms bonded together

Answer explanation

A molecule is defined as a group of two or more atoms bonded together, making this the correct choice. A single atom is not a molecule, and a mixture of solids and gases or a non-moving particle does not accurately describe a molecule.
