Neutral buoyancy refers to the state where an object has neither positive nor negative buoyancy, meaning it neither sinks nor floats. In scuba diving, achieving neutral buoyancy is crucial as it allows divers to hover effortlessly at a specific depth without exerting too much energy. This is important for conserving air, maintaining control and stability underwater, and minimizing damage to the environment.
Question 3: List three types of scuba diving equipment that are essential for every dive.
- Mask: A mask helps the diver see clearly underwater by creating an air pocket around the eyes. It also protects the eyes from water.
- Regulator: A regulator is responsible for delivering air from the scuba cylinder to the diver’s mouth. It allows the diver to breathe comfortably while underwater.
- BCD (Buoyancy Control Device): The BCD helps divers control their buoyancy by inflating or deflating with air. It allows them to ascend, descend, and hover at different depths.
Question 4: What is the purpose of a dive computer, and how does it enhance diver safety?
A dive computer is a device that tracks the depth, time, and nitrogen levels in the diver’s body during a dive. It calculates safe ascent rates and allows the diver to stay within the limits of no-decompression diving. This enhances diver safety by reducing the risk of decompression sickness. The dive computer also provides information on remaining dive time and mandatory decompression stops, ensuring the diver can plan their dive accordingly and avoid unnecessary risks.
Question 5: Explain the concept of the buddy system in scuba diving and why it is essential.
The buddy system in scuba diving is when two divers are paired together and are responsible for each other’s safety throughout the dive. The buddy system is essential because it provides an additional level of safety and support. Buddies can help each other in case of emergencies, share air in case of depletion, and act as a backup in case of equipment failure. By diving with a buddy, divers can have peace of mind knowing that someone is watching their back and they can rely on them for assistance if needed.
These are just a few of the answers to the PADI Knowledge Review 2. By understanding these concepts, you will be better prepared for your scuba diving adventures and have a solid foundation in diving knowledge. Happy diving!

Explaining the True or False Statements
In the Padi knowledge review 2, there are several true or false statements that require explanation. Let’s take a closer look at each statement and provide the correct answer.
Statement 1: Underwater navigation is an important skill for scuba divers.
True. Underwater navigation is indeed an important skill for scuba divers. Being able to navigate underwater allows divers to explore new dive sites, find their way back to the starting point, and avoid getting lost. It involves using a compass, natural navigation cues, and dive planning to ensure safe and organized dives.
Statement 2: Nitrogen narcosis is caused by low levels of nitrogen in the air we breathe.
False. Nitrogen narcosis is actually caused by elevated levels of nitrogen in the air we breathe at depth. As divers descend deeper, the increased pressure causes nitrogen molecules to dissolve into the bloodstream, and when concentrations exceed a certain threshold, it can lead to symptoms similar to alcohol intoxication, such as impaired judgment and decision-making.
Statement 3: A dive computer calculates the diver’s no-decompression limits based on the remaining oxygen in the cylinder.
False. A dive computer calculates the diver’s no-decompression limits based on the accumulated nitrogen in the body, not the remaining oxygen in the cylinder. The dive computer tracks the time and depth of the dive, and uses a mathematical model to estimate the nitrogen saturation and determine the amount of time the diver can safely spend underwater and ascend without needing decompression stops.
Statement 4: A buddy check should be performed before every dive to ensure that all equipment is properly functioning.
True. Performing a buddy check before every dive is an important safety practice. It involves both divers inspecting each other’s equipment to ensure that it is properly set up, functioning correctly, and all necessary safety features are in place. This includes checking the air supply, dive computers, BCD inflators, weight systems, and other equipment that could impact the diver’s safety and comfort underwater.
Statement 5: A dive plan should always include a safety stop at the end of every dive, regardless of depth.
True. A safety stop at the end of every dive is a recommended safety practice, regardless of depth. A safety stop typically involves ascending to a shallower depth for a few minutes, such as 3-5 meters, and waiting there before continuing the ascent to the surface. This allows for off-gassing of excess nitrogen and reduces the risk of developing decompression sickness. It is a precautionary measure that helps ensure a safer diving experience.
Statement 6: The use of dive flags or floats is not necessary when diving in clear, calm waters.
False. The use of dive flags or floats is necessary for the safety of divers, regardless of water conditions.
