Ideal Gas Law

What is the definition of a gas in terms of motion and container?

• Phase of matter where atoms are in motion and fill their container.

  
  

• Phase of matter with fixed shape and volume.

  
  

• Phase of matter with atoms that do not move.

  
  

• Phase of matter where atoms are liquid and fill the bottom of the container.

  
  

Which of the following is an assumption made about ideal gases?

• Particles are large and interact strongly.

• Particles are dimensionless points in random motion.

• Particles only interact through attractive forces.

• The identity of the gas significantly affects its behavior.

If the volume of a gas is compressed while keeping the number of moles and temperature constant, what happens to the pressure?

• It decreases.

• It remains the same.

• It increases.

• It becomes zero.

When performing calculations involving temperature for gas laws, which temperature scale must always be used?

• Celsius

• Fahrenheit

• Kelvin

• Rankine

According to Avogadro's Law, what is true about equal volumes of different gases at the same temperature and pressure?

• They have different numbers of molecules.

• They have the same number of molecules.

• Their volumes are inversely proportional to their temperatures.

• Their pressures are inversely proportional to their volumes.
