Temperature, Pressure, and the States of Matter

Front

What is the state of matter where atoms are in constant motion?

Back

All states of matter (solid, liquid, gas) have atoms in constant motion, but the degree of motion varies.

Front

What happens to particles when the temperature of matter increases?

Back

The particles speed up and move farther apart.

Front

What happens to particles when the temperature of matter decreases?

Back

The particles slow down and move closer together.

Front

What is the characteristic of particles in a solid?

Back

In a solid, particles are closely packed together and vibrate in place.

Front

What is the characteristic of particles in a liquid?

Back

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

Front

What is the characteristic of particles in a gas?

Back

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

Front

Define temperature in the context of matter.

Back

Temperature is a measure of the average kinetic energy of the particles in a substance.

Front

What is pressure in relation to gases?

Back

Pressure is the force exerted by gas particles colliding with the walls of their container.

Front

How does increasing temperature affect gas pressure?

Back

Increasing temperature generally increases gas pressure if the volume is constant.

Front

What is the relationship between temperature and kinetic energy?

Back

As temperature increases, the kinetic energy of the particles increases.
