2. The pressure gauge must have a safety valve that will blow after the glass.
3. If you ascend too quickly the nitrogen is cannot be released quickly enough thus contributing to the formation of bubbles in the divers __________
4. All weight belts must have a quick release buckle, which requires a positive action to open them

23. The ascent starts finning towards the surface, in order to control the speed; the B.C.D. must be ________________.
24. Every time we make a movement we use energy which asks more of our body, requiring a change in the ___________ in order to satisfy this new demand.
25. After a time on the surface the new dive letter group is B. Now wanting to plan a second dive in this case 14 metres for 25 minutes. What is the new dive letter group at the end of the dive?
26. A floating buoy marks the presence of divers underwater. In some countries dive law requires ______________ flag known as an “A FLAG”
27. While you dive, in order to evaluate the hydrostatic equilibrium, is important to consider the relation between volume and weight of:
28. At the end of the a first dive the letter group is H. Now, wanting to plan a second dive, after a break on the surface of 3 hours and 29 minutes. What is the new dive letter group after the time on the surface?
29. Underwater sounds are transmitted ______________ because water has a greater density than air.
