Phases of Matter

Front

What is the Kinetic Theory of Matter?

Back

The Kinetic Theory of Matter states that all matter is made up of particles that are in constant motion.

Front

What are the three main states of matter?

Back

Solid, Liquid, Gas.

Front

What is the building block of matter?

Back

Atoms.

Front

What does the term 'phase change' refer to?

Back

A phase change refers to the transition of matter from one state to another, such as melting, freezing, or boiling.

Front

What are electrons?

Back

Electrons are negatively charged particles that orbit the nucleus of an atom.

Front

What is the Periodic Table of Elements?

Back

The Periodic Table of Elements is a tabular arrangement of all known chemical elements, organized by their atomic number, electron configuration, and recurring chemical properties.

Front

What is the difference between a solid, liquid, and gas in terms of particle arrangement?

Back

In solids, particles are closely packed in a fixed arrangement; in liquids, particles are close but can move past each other; in gases, particles are far apart and move freely.

Front

What happens to the particles in a substance when it is heated?

Back

When a substance is heated, its particles gain energy and move faster, which can lead to a phase change.

Front

What is the role of temperature in the states of matter?

Back

Temperature affects the energy of particles, influencing their movement and the state of matter.

Front

What is the definition of a gas?

Back

A gas is a state of matter that has no fixed shape or volume, and its particles are widely spaced and move freely.
