According to Boyle's Law, if the pressure of a gas increases, what happens to the volume, assuming the temperature is constant?

• Volume increases

• Volume decreases

• Volume stays the same

• Volume fluctuates

Which of the following is a direct relationship as stated in Charles's Law?

• Volume and pressure

• Pressure and temperature

• Volume and temperature

• Volume and moles

A gas occupies a volume of 2.0 L at 1.0 atm pressure. What will its volume be if the pressure is increased to 2.0 atm, assuming constant temperature?

• 4.0 L

• 2.0 L

• 1.0 L

• 0.5 L

The temperature of a gas is increased, and the volume is held constant. What will happen to the pressure?

• It decreases

• It remains the same

• It increases

• It fluctuates

If a gas's volume is doubled and its temperature is also doubled, according to the combined gas law, what happens to the pressure?

• It is halved

• It is doubled

• It remains the same

• It is quadrupled

Which of the following gas laws is described by the relationship between the volume of a gas and its temperature at constant pressure?

• Boyle's Law

• Charles's Law

• Dalton's Law

• Avogadro's Law

A 3.0 L balloon is inflated at 20°C. If the temperature is increased to 40°C, what will happen to the volume of the balloon, assuming constant pressure?

• It will decrease

• It will remain the same

• It will increase

• It will double

Which statement is true according to the ideal gas law?

• Gas volume and temperature are inversely proportional

• Pressure and volume are proportional

• Volume and pressure are directly proportional

• Pressure, volume, and temperature are related in a single equation

What is the ideal gas law equation?

• PV = nRT

• P1V1/T1 = P2V2/T2

• V = nRT/P

• P = nRT/V

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