Physical Science Final Exam

Front

What is a supersaturated solution?

Back

A solution that contains more solute than it can normally hold at a given temperature, achieved by heating the solution to dissolve more solute and then cooling it down.

Front

What does Boyle's Law state about the relationship between pressure and volume of a gas at constant temperature?

Back

As the pressure of a given sample of gas increases, the volume decreases.

Front

How does temperature affect the movement of particles in a substance?

Back

At higher temperatures, particles in an object move faster.

Front

What are the three main variables involved in gas laws?

Back

Pressure, Temperature, Volume.

Front

Rank the types of radiation in order of penetrating power from most to least: Alpha, Beta, Gamma.

Back

Gamma, Beta, Alpha.

Front

What happens to the volume of a gas when the pressure is increased, according to Boyle's Law?

Back

The volume decreases.

Front

What is the effect of heating a solution on its solubility?

Back

Heating a solution generally increases its solubility, allowing more solute to dissolve.

Front

Define pressure in the context of gases.

Back

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

Front

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

Back

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

Front

What is the definition of a gas?

Back

A state of matter with no fixed shape or volume, where particles are far apart and move freely.
