Exploring the Ideal Gas Law and Its Applications

What happens to the marshmallow in a vacuum?

• It shrinks due to increased pressure

• It expands as the air bubbles inside expand

• It dissolves

• It remains unchanged

What is the relationship between temperature and volume according to the Ideal Gas Law?

• Directly proportional

• Inversely proportional

• Not related

• Proportional to the square of the temperature

What is the purpose of the airbag design challenge?

• To test the durability of plastic bags

• To optimize a chemical reaction for airbag inflation

• To study the effects of air pressure

• To create a new type of gas

What are the reactants in the airbag experiment?

• Hydrochloric acid and sodium hydroxide

• Acetic acid and sodium bicarbonate

• Sulfuric acid and potassium permanganate

• Nitric acid and calcium carbonate

What gas law is used to predict the behavior of gases in the airbag experiment?

• Avogadro's Law

• Ideal Gas Law

• Charles's Law

• Boyle's Law

What must be measured to calculate the amount of gas needed for the airbag?

• The weight of the plastic bag

• The volume of the plastic bag

• The thickness of the plastic bag

• The color of the plastic bag

What does the ideal gas law equation PV=nRT stand for?

• Power, Velocity, neutrons, Radiation, Time

• Pulse, Velocity, neutrons, Reactivity, Temperature

• Pressure, Volume, moles, R constant, Temperature

• Potential, Viscosity, mass, Resistance, Thermal energy

What is the role of the Universal Gas Constant (R) in the ideal gas law?

• It represents the rate of reaction

• It is a proportionality constant that relates the variables in the equation

• It indicates the volume of the gas

• It determines the pressure of the gas

What safety equipment is necessary for the airbag experiment?

• Earplugs and sunglasses

• Gloves and boots

• Safety goggles and apron

• Helmet and knee pads

Why might the chemical reaction in the airbag experiment be less than 100% efficient?

• Due to the quality of the reactants

• Because of experimental error

• All chemical reactions are 100% efficient

• The reaction produces less carbon dioxide than calculated theoretically
