Question 1: Define Boyle's Law in your own words.

Answer: Boyle's Law states that at constant temperature, the pressure of a gas increases as its volume decreases, and vice versa, such that their product remains constant.

Question 2: What are the typical units used to measure gas pressure and volume?

Answer: Pressure is measured in atmospheres (atm), pascals (Pa), or kilopascals (kPa); volume is measured in liters (L) or cubic meters (m³).

Question 3: Explain why the temperature must be held constant when applying Boyle's Law.

Answer: Because Boyle's Law assumes constant temperature, which means the kinetic energy of gas particles remains unchanged, ensuring the relationship between pressure and volume stays consistent.

Question 1: A gas sample has a volume of 3.0 L at a pressure of 1.0 atm. What will its volume be if the pressure is increased to 2.0 atm, assuming temperature remains constant?

Answer: V₂ = 1.5 L

Question 2: A container holds a gas at 4.0 liters and a pressure of 0.8 atm. If the volume decreases to 2.0 liters, what is the new pressure?

Answer: P₂ = 1.6 atm

Question 1: Describe a simple experiment to demonstrate Boyle's Law using a syringe and a pressure gauge.

Answer: Pulling the syringe plunger increases volume and decreases pressure; pushing it in decreases volume and increases pressure. A pressure gauge can be attached to measure changes, illustrating the inverse relationship.

Question 2: List two safety precautions to consider when performing experiments involving compressed gases.

Answer: Ensure proper venting to prevent pressure build-up and handle equipment carefully to avoid leaks or bursts.

Question 1: A sealed container initially has a volume of 5.0 L at a pressure of 1.0 atm. When the pressure is increased to 3.0 atm, what is the new volume of the gas? Explain your reasoning.

Answer: Using Boyle's Law (P₁V₁ = P₂V₂), V₂ = (P₁ × V₁) / P₂ = (1.0 atm × 5.0 L) / 3.0 atm = 1.67 L. As pressure increases, volume decreases proportionally, demonstrating Boyle's Law.

Question 1: Identify a real-world industry or application where Boyle's Law is utilized. Describe how it is applied.

Answer: In scuba diving, Boyle's Law explains how increasing pressure at greater depths compresses air in tanks and body cavities, necessitating careful ascent to avoid injuries caused by rapid pressure changes.

Question 2: Explain how Boyle's Law is important in the design of syringes and vacuum pumps.

Answer: Boyle's Law underpins the operation of syringes and vacuum pumps, where decreasing the volume of a sealed chamber increases pressure, enabling the drawing in or expelling of fluids or air efficiently and safely.
