Chem Review

Which of the following best describes the movement of particles in a solid?

• The particles move freely and rapidly, colliding with each other.

• The particles are tightly packed and vibrate in their fixed positions.

• The particles are spread out and move randomly, filling the container.

• The particles are ionized and exhibit electrical conductivity.

Which statement accurately compares the behavior of particles in a gas to particles in a liquid?

• Particles in a gas are more random and disorganized compared to particles in a liquid.

• Particles in a gas stick together more than particles in a liquid.

• Particles in a gas are more attracted to each other than particles in a liquid.

• Particles in a gas move slower and collide less frequently with each other compared to particles in a liquid.

According to the kinetic-molecular theory of matter, particles of matter...

• have different shapes

• have different colors

• are always fluid

• are in constant motion

Which of the following is true about plasma?

• It has a definite shape and definite volume

• It is composed of neutral particles

• It is composed on positive and negatively charged ions

• It does not conduct electricity because it is neutral

The boiling point of a substance is the same as it’s...

• Condensation point

• Freezing point

• Melting point

• Sublimation point

The process of plasma becoming a gas:

• Sublimation

• Ionization

• Neutralization

• Electricity

Which of the following is IS true of evaporation?

• Is an exothermic change of state

• Occurs only at the surface of a liquid

• Occurs throughout the liquid, involves convection

• Only occurs after the boiling point has been reached

Which of the following statements best describes the relationship between temperature and volume of a gas in a closed system, according to Charles' Law?

• As temperature increases, volume also increases when pressure is held constant

• As temperature increases, volume decreases when temperature is held constant

• Temperature has no effect on the volume of a gas

• It is impossible to determine the relationship between temperature and volume based on Charles' Law.

Which of the following describes the relationship in Boyle's law?

• Increase in pressure, increase in volume

• Increase in temperature, decrease in volume

• Increase in pressure, decrease in volume

• Increase in pressure, decrease in temperature
