• The collisions between gas particles are elastic.
• The collisions between gas particles are not elastic.
• The collisions between gas particles are semi elastic.
• The collisions between gas particles are half elastic.

Which of the following graphs represent Charles’ law CORRECTLY.

• 
• 
• 
• 

“Total pressure of a mixture of non reacting gases is equal to the sum of the pressures that each gas would have if it were present alone.” The above statement refer to

• Boyle’s law
• Charles' law

• Avogadro’s law
• Dalton’s law

According to Charles' law, what happens to the volume of a gas when the temperature increases at constant pressure?

• The volume decreases.

• The volume remains constant.

• The volume increases.

• The volume fluctuates.

What is the primary assumption of the ideal gas law regarding gas particles?

• Gas particles have significant volume.

• Gas particles attract each other.

• Gas particles are in constant random motion.

• Gas particles do not collide with each other.

What happens to the pressure of a gas when its volume decreases at constant temperature?

• The pressure decreases.

• The pressure remains constant.

• The pressure increases.

• The pressure fluctuates.

Which of the following statements is TRUE regarding the behavior of real gases compared to ideal gases at high pressure and low temperature?

• Real gases behave more like ideal gases.

• Real gases deviate from ideal behavior.

• Real gases have no intermolecular forces.

• Real gases occupy no volume.

According to Avogadro's law, what is the relationship between the volume of a gas and the number of moles at constant temperature and pressure?

• The volume is directly proportional to the number of moles.

• The volume is inversely proportional to the number of moles.

• The volume is independent of the number of moles.

• The volume is equal to the number of moles.

Gas pressure is caused by

• left container

• right container

• they both have the same pressure

• I don't know
