SPS5. Phases of Matter

Front

What are the three main phases of matter?

Back

Solid, Liquid, Gas.

Front

Which phase of matter has the least amount of energy in its particles?

Back

Solid.

Front

Which phase of matter has the most tightly packed particles?

Back

Solid.

Front

What happens to the pressure of a gas when its temperature is doubled in a closed container?

Back

The pressure of the gas also doubles, because temperature and pressure are directly related.

Front

What occurs to the volume of CO2 in soda when the pressure decreases after shaking the can?

Back

The volume of CO2 increases.

Front

What is the relationship between temperature and pressure in gases?

Back

They are directly related; as temperature increases, pressure increases.

Front

What happens to air molecules in a scuba tank as more air is added?

Back

They move and collide faster, raising the temperature.

Front

What is the characteristic of particles in a solid phase?

Back

They are tightly packed and vibrate in place.

Front

What is the characteristic of particles in a liquid phase?

Back

They are close together but can move past one another.

Front

What is the characteristic of particles in a gas phase?

Back

They are far apart and move freely.
