Multiple Choice

Based on Boyle's Law, what happens to weather balloons as they rise higher in the atmosphere?

• The pressure OUTSIDE of the balloon increases and the balloon CONTRACTS

• The pressure OUTSIDE of the balloon decreases and the balloon CONTRACTS

• The pressure OUTSIDE of the balloon increases and the balloon EXPANDS

• The pressure OUTSIDE of the balloon decreases and the balloon EXPANDS

Multiple Choice

According to Boyle's Law, if the temperature stays the same and the volume of the container is decreased, then the pressure from the gas will

• Decrease

• Stay the same

• None of the above

Multiple Choice

What is the equation for Boyle's Law?

• initial pressure + initial volume = final pressure + final volume

• initial pressure - initial volume = final pressure - final volume

• initial pressure x initial volume = final pressure x final volume

• initial pressure / initial volume = final pressure / final volume

• Liters

• Pascals

• PSI

• Parsecs

Multiple Choice

Which of the following BEST explains Charles' Law?

• If the pressure on a gas is kept constant, then the volume INCREASES as the temperature DECREASES

• If the pressure on a gas is kept constant, then the volume DECREASES as the temperature INCREASES

• If the pressure on a gas is kept constant, then the volume INCREASES as the temperature INCREASES

• None of the above

Multiple Choice

Which BEST connects the ideas of Charles' Law to the Kinetic Theory?

• As the temperature INCREASES the particles in a gas move more SLOWLY, so if the pressure is kept the same, the volume must INCREASE

• As the temperature INCREASES the particles in a gas move more QUICKLY, so if the pressure is kept the same, the volume must INCREASE

• As the temperature DECREASES the particles in a gas move more SLOWLY, so if the pressure is kept the same, the volume must INCREASE

• None of the above

Multiple Choice

Which of the following is the BEST equation for Charles' Law?

• Initial Volume + Initial Temperature = Final Volume + Final Temperature

• Initial Volume - Initial Temperature = Final Volume - Final Temperature

• Initial Volume x Initial Temperature = Final Volume x Final Temperature
