The numbers on a scuba tank reveal 3 things. Serial no. of the tank. Type metal. and the current hydro date.
Yes, the oxygen and helium in a scuba tank are pure substances because they consist of only one type of molecule and cannot be separated by physical means.
I would think so, because there are two of them mixed together. Air in a scuba tank or anywhere else should be heterogeneous. A scuba tank filled with either oxygen or nitrogen would be homogeneous.
Well... It depends on what you mean by dive... do you mean dive of a board or dive with a scuba tank. eather way as long as its not Fresh fresh you will be fine
Most SCUBA divers dive with compressed air, which is normal atmospheric air compressed into a scuba tank.
Yes, the oxygen and helium in a scuba tank would be considered a homogeneous mixture because they are evenly distributed throughout the tank and have uniform properties throughout.
The distance you can go before running out of oxygen depends on factors like your level of physical activity and the volume of oxygen in your tank. On average, a scuba diver with a standard tank can go from 30 minutes to an hour at recreational depths before running out of oxygen. It is essential to monitor your oxygen levels and plan your dive accordingly.
so they can breath underwater
They probably wear scuba gear,flippers,a whole suit,and an oxygen tank.
It would need to be empty, have the valve open, and it needs to have the cover off. It isn't good for your tank, so you might as well just rent a tank at the dive shop there, if that was what you were thinking. It is expensive to ship a scuba tank as well.
Different scuba gear types weigh different amounts. The oxygen tank is the heavy part of the scuba diving gear.
Theoretically if you had your own gear, including tank of air, you can dive anywhere that's got water but it's not recommended unless you know the dive site. If you don't have a licence, a dive centre should not allow you to dive. They can take you out on a "discover scuba diving" dive. This will be to a maximum of 12m. If you are qualified but have forgotten or lost your cert card, they can look you up on the pro website. If not qualified with at least PADI scuba diver cert, no one should let you dive. If they do, I would think twice about the dive operation you are using.
