Question 1: Boyle's Law states that for a fixed amount of gas at constant temperature, the pressure and volume are inversely proportional. This means that if the volume of a gas decreases, its pressure increases, and vice versa. The mathematical expression is P1V1 = P2V2, where P is pressure and V is volume.

Answer: Boyle's Law states that for a fixed amount of gas at constant temperature, pressure and volume are inversely proportional, expressed as P1V1 = P2V2.

Question 1: Define Boyle's Law and explain its significance in real-world applications.

Answer: Boyle's Law states that pressure and volume of a gas are inversely proportional at constant temperature. It is significant in applications like syringes, scuba diving, and engineering designs involving gases.

Question 2: Describe a simple experiment to demonstrate Boyle's Law using a syringe, a pressure gauge, and water.

Answer: Insert a pressure gauge into a sealed syringe filled with water. Vary the syringe's volume by pulling or pushing the plunger and observe the change in pressure. As volume decreases, pressure increases; as volume increases, pressure decreases, demonstrating Boyle's Law.

Question 3: Which of the following scenarios best illustrates Boyle's Law? A) Heating a gas in a sealed container B) Compressing a gas in a syringe C) Melting ice D) Boiling water

Answer: B

Question 1: A gas occupies 3.0 liters at a pressure of 1.2 atmospheres. If the pressure is increased to 2.4 atmospheres at constant temperature, what is the new volume of the gas? (Use Boyle's Law: P1V1=P2V2)

Answer: V2 = (P1 × V1) / P2 = (1.2 atm × 3.0 L) / 2.4 atm = 1.5 liters

Question 2: A balloon has a volume of 5 liters at a pressure of 1 atm. If the volume is reduced to 2 liters, what is the pressure inside the balloon, assuming constant temperature?

Answer: P2 = (P1 × V1) / V2 = (1 atm × 5 L) / 2 L = 2.5 atm

Question 3: Describe how the pressure of a gas changes when its volume is doubled at constant temperature.

Answer: The pressure decreases by half because pressure and volume are inversely proportional according to Boyle's Law.

Question 1: Explain how Boyle's Law is utilized in the operation of a scuba diver's air tank and why safety measures are important.

Answer: In scuba diving, Boyle's Law explains how increasing depth causes pressure to rise, compressing the air in the tank and lungs. Divers must monitor pressure to avoid over-expansion or collapse of lungs, making safety precautions essential to prevent injuries such as barotrauma.

Question 2: Identify and explain two safety precautions when conducting experiments related to Boyle's Law.

Answer: Use pressure gauges to monitor pressure levels, and ensure containers are rated to withstand maximum expected pressures to prevent explosions or leaks.

Question 3: In everyday life, how does Boyle's Law help in the functioning of an aerosol spray can?

Answer: When the nozzle is pressed, the volume inside the can decreases, increasing pressure and forcing the contents out as a spray, demonstrating Boyle's Law in action.
