Changing States of Matter

Front

What is viscosity?

Back

Viscosity is a measure of a fluid's resistance to flow. A liquid with high viscosity, like honey, flows slowly.

Front

What happens to gas particles when temperature increases?

Back

When the temperature of a gas increases, the particles move faster, leading to higher energy and pressure.

Front

What is surface tension?

Back

Surface tension is a property of liquids that causes the surface to behave like a stretched elastic membrane, allowing small objects to float.

Front

What is boiling?

Back

Boiling is a type of vaporization that occurs both below and at the surface of a liquid when it reaches its boiling point.

Front

What does Boyle's Law state?

Back

Boyle's Law states that at constant temperature, the pressure of a gas is inversely proportional to its volume.

Front

What is condensation?

Back

Condensation is the process by which gas turns into a liquid when it cools down.

Front

What is sublimation?

Back

Sublimation is the process where a solid changes directly into a gas without becoming a liquid first.

Front

What is the difference between evaporation and boiling?

Back

Evaporation occurs at the surface of a liquid at any temperature, while boiling occurs throughout the liquid at a specific temperature.

Front

What is a fluid?

Back

A fluid is a substance that can flow and take the shape of its container, including liquids and gases.

Front

What is the relationship between pressure and volume in gases?

Back

As the volume of a gas decreases, its pressure increases, provided the temperature remains constant.
