If the original pressure of a container of gas is 40^oC at a pressure of 1.00 atm, what will the new pressure be if the temperature is decreased to 20^oC?

• 0.50 atm

• 2.00 atm

• 1.50 atm

• 0.94 atm

Rearrange the equation to solve for "n"

• n = RT / PV

• n = PVRT

• n = PV / RT

Consider the research question, "Does changing the volume of a gas affect the gas pressure?" Identify the independent and dependent variables in the experiment.

• volume is dependent, pressure is independent

• volume is independent, pressure is dependent

• both volume and pressure are independent

• more information is needed

Answer explanation

the dependent variable will change DEPENDING on the changes you made to the independent

• Boyle's Law

• Charles's Law

• Ideal Gas Law

• Avogadro's Law

If the volume of a gas is doubled while the temperature and amount of gas remain constant, what happens to the pressure?

• The pressure doubles

• The pressure is halved

• The pressure remains constant

• The pressure quadruples

Which of the following variables is directly proportional to the pressure of a gas, assuming the amount of gas and volume are constant?

• Temperature

• Volume

• Moles of gas

• None of the above
