Heat and Water in theory:
As we learned, water absorbs heat faster then air does. But why is that? There are several reasons why heat absorption is greater in water. One of them is that water is denser or has a greater thickness of matter than air. It also means water has more mass = molecules for a given volume. Heat is the energy what gets molecules moving. Hence the denser (more molecules) a substance is, the more energy (heat) it needs, which means it absorbs heat faster then a less denser substance like air for example. Another point is also the bonds within the molecules which are so called weaker or more elastic which needs more energy (heat) to overcome. So to summarize, water needs more heat energy to rise to a given temperature.

Everyone remembers their first dive in the ocean. The first time you dip under the surface and you enter a whole new world. Your first dive could have been a Discover Scuba diver course or it was part of your Open Water Course. Either way if you are reading this blog, you loved it and are now a certified Open Water Diver who loves to dive and wants to take the next step in diving.

Every regulator needs servicing. How often depends on the manufacturer's recommendations, mostly once a year. So, you go to your dive shop, handover the regulator and probably a few days or week later you are back to pick it up. It looks cleaner, there is a small bag with parts and that is about it. You use the regulator again and chances are you don’t really notice the difference (except if you brought in your regulator with some issues). So what’s the point?

Let's have a look at scuba tanks, we kind of take them for granted, you arrive at the shop, get a scuba tank, we connect them to our BCD and regulator and go diving.
Scuba tanks are relatively small, yet very strong that hold large volumes of compressed gas.
