Phases of Matter

Front

What is plasma?

Back

Plasma is a state of matter where electrons are separated from atoms, resulting in a collection of charged particles. It is the hottest state of matter.

Front

How does gas differ from plasma?

Back

Gas consists of neutral atoms or molecules, while plasma contains charged particles due to ionization. Plasma is generally hotter than gas.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of motion. In gases, particles have the most kinetic energy, allowing them to move rapidly.

Front

What phase of matter has a definite shape and volume?

Back

Solid has a definite shape and volume.

Front

What phase of matter has a definite volume but no definite shape?

Back

Liquid has a definite volume but takes the shape of its container.

Front

What is the state of matter with the lowest heat energy?

Back

Solid is the state of matter with the lowest heat energy and temperature.

Front

What happens to particles in a gas?

Back

In a gas, particles are far apart and move freely, allowing them to fill the entire volume of their container.

Front

What is the relationship between temperature and kinetic energy in gases?

Back

As temperature increases, the kinetic energy of gas particles also increases, causing them to move faster.

Front

What is an example of plasma?

Back

Examples of plasma include stars, lightning, and neon signs.

Front

What is the process of changing from a solid to a liquid called?

Back

Melting is the process of changing from a solid to a liquid.
