States of Matter Practice

Front

What happens to the particles of matter when the temperature increases?

Back

The particles speed up and move farther apart, decreasing intermolecular forces.

Front

What happens to the particles of matter when the temperature decreases?

Back

The particles slow down and move closer together.

Front

What are plasmas?

Back

Plasmas are ionized gases.

Front

What occurs during a phase change from liquid to gas in terms of temperature and energy?

Back

Energy increases but temperature stays the same.

Front

Is evaporation an endothermic or exothermic process?

Back

Evaporation is endothermic because energy is gained by the particles.

Front

Define solid in terms of particle arrangement.

Back

In solids, particles are closely packed in a fixed arrangement.

Front

Define liquid in terms of particle arrangement.

Back

In liquids, particles are close together but can move past one another, allowing them to flow.

Front

Define gas in terms of particle arrangement.

Back

In gases, particles are far apart and move freely, filling the container they are in.

Front

What is the relationship between temperature and kinetic energy of particles?

Back

As temperature increases, the kinetic energy of particles increases.

Front

What is sublimation?

Back

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