  45. Quiz 1 – BQuestion 1 • Displacement of water more than own weight –object will float (positively buoyant) • Displacement of water less than own weight –object will sink (negatively buoyant) • Displacement of water equal to own weight – object will neither float nor sink (neutrally buoyant) • If an object neither sinks nor floats it is neutrally buoyant Return toQuestion Quiz 1-B Question 1 - PLG

  46. Quiz 1 – BQuestion 2 • Buoyancy - the weight of water volume displaced • The heavier the water - the greater the buoyancy for a given displacement • Salt water weighs more than fresh water • You’re more buoyant in salt water than in fresh • An object neutrally buoyantin fresh water will float if putinto salt water Return toQuestion Quiz 1-B Question 2 - PLG

  47. Quiz 1 – BQuestion 4 • Air added to an air space to maintain volume expands when you reduce the pressure • In an open container, such as a glass, excess air simply bubbles out into the surrounding water as you ascend • Air added to a glass expands when you reduce the pressure Return toQuestion Quiz 1-B Question 4 - PLG

  48. Quiz 1 – BQuestion 7 • In an open container - excess air bubbles out into the surrounding water during ascent • In a closed flexible container - the air is trapped and expands as you ascend • 10 metres/33 feet is 2 atmospheres • If you inflate a balloon at 10 metres/33 feet and take it to the surface, it will expand to twice the size as it was at 10 metres/33 feet Return toQuestion Quiz 1-B Question 7 - PLG

  49. Quiz 1 – BQuestion 9 • Rinse your regulator with warm running water • When rinsing your regulator: • Put the first stage dust cover firmly in place • Do not use high-pressure water to rinse • Don’t press the purge button while rinsing or soaking - this opens the second stage inlet valve and can allow water to flow up the hose into the first stage Return toQuestion Quiz 1-B Question 9 - PLG

  50. Quiz 2 – BQuestion 5 • Wet suits reduce heat loss - a layer of insulating foam neoprene over your skin • Your body quickly heats the water – as longas water remains trapped in your suit youstay warm • If water circulates in and out of your suit –you lose a lot of heat to incoming cold water • Wet suits need to have a proper snug fit Return toQuestion Quiz 2-B Question 5 - PLG
