The state of matter that has a definite shape and a definite volume. Solids cannot flow and are not easily compressed.

The state of matter that has no definite shape but does have a definite volume. Liquids can flow and take the shape of their container, but they're not easily compressed.

The state of matter that has no definite shape and no definite volume. Gases can flow and take the shape of their container, and they're very compressible.

The process where a solid turns into a liquid. It's also known as melting.

The process where a liquid turns into a solid. It's also known as freezing.

The process where a liquid changes into a gas. It's also referred to as evaporating.

The process where a gas changes into a liquid. It's the opposite of boiling.

The forces that attract molecules or particles to each other.

Strength of forces between particles determines the ability of the substance to change shape, volume, and flow.

The state of matter where particles are tightly packed together, vibrate in place, and have a fixed shape and volume.

The state of matter where particles are close together but can slide past each other, allowing for shape change and flow.

The state of matter where particles are far apart, move randomly at high speeds, and have no fixed shape or volume.

The ability of a gas to be compressed or expanded due to the large spaces between particles.

The ability of a gas to fill any container due to the movement of particles.

The ability of a substance to flow freely because particles can move past each other.

Particles can be atoms, molecules, ions, or electrons.

The energy of motion possessed by particles. The faster the particles move, the more kinetic energy they have.

The average speed of particles in a gas increases as the temperature increases.

The pressure a gas exerts on its container is directly related to its temperature. Higher temperature means higher pressure.

The theoretical point where all particle motion stops, resulting in zero kinetic energy. It is the lowest possible temperature.

The unit of measurement for temperature on the Kelvin scale. Absolute zero is 0 Kelvin.

A measure of the average kinetic energy of particles in a substance.

The state of matter where particles have the highest kinetic energy and are spaced furthest apart.

The temperature scale where 0 represents the absolute zero point, where all molecular motion ceases.

A gas's pressure increases when its temperature rises, but its volume remains constant. This is because the molecules move faster, hit the container walls more often and with greater force.

The random movement of microscopic particles suspended in a fluid, caused by collisions with the invisible atoms and molecules of the fluid.

A rule that states that for a fixed amount of an ideal gas at a constant temperature, the pressure and volume are inversely proportional. This means that if the pressure increases, the volume decreases, and vice versa.

Particles that are too small to be seen with the naked eye, but can be seen with a microscope.

A gas is compressed when its volume decreases. The molecules strike the container walls more frequently, leading to a larger net force and increase in pressure.

The particles that make up a substance, such as water or air, that are too small to be seen even with a microscope.

The average speed of gas molecules increases as the temperature increases. This is because the molecules have more kinetic energy, which is energy of motion.

The relationship between pressure and temperature at a constant volume. The graph of pressure versus temperature is a straight line, indicating that the pressure is directly proportional to the temperature.

Inferences are conclusions drawn from observations and evidence.

The process of determining the presence or properties of something that cannot be directly observed, by studying its effects on something that can be observed.

The idea that scientific conclusions are based on evidence and reasoning, rather than simply what we can see.

The force exerted by the collisions of atoms and molecules with a larger particle.

The random motion of particles caused by the continuous bombardment of atoms and molecules.

The explanation that the random movement of microscopic particles is due to the collisions with smaller, unseen atoms and molecules.
