What does Boyle's law describe?

• How to sink

• The relationship between gas volume and pressure

• How to float

• The relationship between weight and water

What is the function of a dive mask?

• Help with buoyancy

• Enhancing visibility underwater

• Improve dive aesthetic

• Act as an anchoring point for cameras

What is the primary role of a snorkel in diving?

• Provides gas from cylinder

• Facilitates breathing at the surface to preserve tank air

• Enhances visibility underwater

• Allows the diver to descend with ease

What is the purpose of dive fins?

• Provide air to breathe

• Control buoyancy

• Storage for weights

• Enhance propulsion and overcome resistance underwater

Which piece of dive equipment helps protect the diver from the cold and provides thermal insulation

• Fins

• Buoyancy Control Device (BCD)

• Wetsuit

• Snorkel

What is the primary role of a BCD (buoyancy control device)?

• Storing dive accessories

• Providing air to breath

• Maintaining body temperature

• Controlling buoyancy underwater

What piece of dive equipment is responsible for providing a diver air to breath?

• Buoyancy Control Device (BCD)

• Dive computer

• Mask

• Regulator

Why is nitrox preferred by many divers?

• It allows for longer dive times and reduces the risk of decompression illness

• The tank is more colourful and may look better with a wetsuit

• More expensive

• Heavier

What piece of dive equipment is used to manage the depth and time of a dive?

• Dive computer

• Fins

• Mask

• Dive belt

Why is a weight belt required when diving?

• Informs you of the depth you're at

• Enhances propulsion whilst diving

• Improves visibility

• To overcome the natural tendency to float, and allow a diver to descend
