Boyle’s Law

What happens to air bubbles exhaled by a diver as they ascend?

• They shrink in size

• They expand as pressure decreases

• They remain the same size

• They increase in density

If a diver’s lungs contain 2L of air at the surface (1 atm), what will the volume be at a depth of 10 meters (2 atm)?

• 4 L

• 2 L

• 1 L

• 0.5 L

What is the key outcome of Boyle’s Law experiments?

• Volume decreases as temperature increases

• Volume remains constant at high pressure

• Volume is inversely proportional to pressure

• Volume is directly proportional to pressure

What happens to gas molecules in the lungs during ascent if air isn’t exhaled?

• The molecules expand, leading to overinflation of the lungs

• The molecules condense, reducing lung volume

• The pressure inside the lungs decreases

• The volume of the gas remains constant

Which mathematical expression represents Boyle’s Law?

• P × V = k

• P + V = k

• P/V = k

• P – V = k

A diver’s lung volume expands from 6L to 30L during ascent. What does this indicate about pressure at depth?

• Pressure at depth is lower

• Pressure at depth is higher

• Pressure at depth equals surface pressure

• Volume and pressure are unrelated

What happens to gas concentration as surrounding pressure increases?

• It decreases

• It increases

• It remains constant

• It fluctuates

Which factor is directly proportional to the volume of a gas in Boyle's Law?

• Temperature

• Pressure

• Reciprocal of pressure

• The number of gas molecules

Why is it dangerous to hold your breath during ascent after breathing compressed air?

• The air will expand, causing lung overinflation

• The air will shrink, reducing oxygen levels

• The lungs will fill with water

• The pressure will remain constant

What is the formula for Boyle's Law?

• P₁V₁=P₂V₂

• P₁V₁/P₂V₂

• P₁V₂=P₂V₁

• P₁/V₁=P₂/V₂
