4. At the end of the a first dive the letter group is F. 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?
5. underwater the objects appear _____________by about 1/3, water also absorbs light, an effect that increases with wather depth.
6. The water pressure on the eardrum must be balanced by internal pressure so that it is not damaged. It is necessary to compensate ______________________, without waiting to feel the pain
7. The speed at which sound travels through water makes it difficult for his senses to judge _______________
8. Depth gauge is an instrument that measures the depth before a dive.
9. The speed at which sound travels through water makes it difficult for his senses to judge _______________
10. On dive tables the time and depth of the dive are correlated.
11. “At a constant temperature the volume of a gas varies _____________ with absolute pressure while the density of a gas varies ________ with absolute pressure”
12. On resurfacing it may be necessary to ______________________ to obtain positive buoyancy or to be able to come out of the water more easily
13. First aid for Decompression Sickness: the application of pure oxygen guarantees greater oxygenation of __________ and helps to lessen the risk of damage
14. All weight belts must have a quick release buckle, which requires a positive action to open them
15. The regulator enables the diver to breathe underwater. This part the equipment allows _________________.
16. During a dive careful attention needs to be paid to controlling the buoyancy, which should be_______________
17. The BCD is used to_____________________
18. Always have a keeper on _________________ side of the weightbelt from the buckle.
19. 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?
20. The air that we breathe is composed of a mixture of gases, for simplicity let’s say that is made up mainly of________________________
21. Descending and ascending through the bubbles discharged by another diver below, can cause dizziness, try not to look at the bubbles.
22. The snorkel allows breathing on the surface with the head underwater thus keeping the seabed in sight
23. When diving without reference points and in reduced visibility, the _______________ supplies the diver with information of the route and helps with the return to the starting point.
24. The “Octopus” It is fixed to _____________________ of the first stage through a hose than the normal one.
25. Every time that our body undergoes a loss of heat it responds by trying to maintain a constant temperature in the central zone. This is:
26. 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?
27. It is very important before assembly a regulator check the condition of______________
28. The tendency of the body to float is:
29. Before a dive it is good to carry out a thorough check with your buddy, helping him/her to prepare and put on the equipment before entering the water.
30. At the end of the a first dive the letter group is E. 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?
31. If we want to dive, ________________________, the B.C.D. must be deflated by using the exhaust valve.
32. Knifes must be used ________________________.
33. By wearing a mask, an air space is placed between the diver’s eyes and the water so the objects can be_______________________
34. After the use the mask must be rinsed with fresh water and replaced with the glass downwards so that the soft part does not become deformed.
35. You plan a dive at 23 metres for 23 minutes. What is the corresponding dive letter group when you finsh the dive?
36. A whistle is important because it can call to the fishes.
37. When you plan a dive the first thing is to establish the maximum depth to be reached, for examples 13 metres, naturally considering 15 metres on the tables following down the column the limit of permanence at this depth is shown at 100 minutes. Planning to dive for 35 minutes, 30 minutes must be calculated. At this point on the right the corresponding dive letter group, in this case F is found.
38. The pressure gauge must have a safety valve that will blow after the glass.
39. In the case of loss of regulator it is necessary to ascent and continue to
40. Several techniques exist for entering into the water these have always been developed with the safety of the ___________ as a primary consideration.
41. The BCD is also equipped with four or more valves to avoid the risks of over inflating it.
42. A floating buoy marks the presence of divers underwater. In some countries dive law requires ______________ flag known as an “A FLAG”
43. Wet suits are generally made of silicone, of different thickness (from 1.5 to 8 mm), lined on the inside and outside with special cloth that make them more comfortable.
44. The BCD must be slowly deflated during ascent, because the air inside it expands and creates an ________________________and subsequent loss of control of speed. (max. 9 meter/minutes)
45. For the assembly of regulator there are two types of fitting: INT with five or seven thread female and DIN with a yoke (A clamp).
46. You plan a dive at 29 metres for 22 minutes. What is the corresponding dive letter group when you finsh the dive?
47. 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.
48. A divelog well kept is a document that shows the divers experience but is of much less value than a certificate.
49. At a depth of 27 metres, the pressure inside the lungs will be the equivalent of the ambient pressure:
50. Nitrogen narcosis effects different divers differently depending on the ___________________
