Is the oxygen and helium in a scuba tank an example of a homogeneous mixture?
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.
Is the oxygen and helium in a scuba tank a pure substance?
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.
Is the oxygen and helium in a scuba tank a compound or heterogeneous?
The oxygen and helium in a scuba tank are considered a homogeneous mixture, not a compound or a heterogeneous mixture. In this case, the gases are mixed together uniformly, and their individual properties remain unchanged. A compound consists of two or more elements chemically bonded together, while a heterogeneous mixture would have distinct, separate components.
How much oxygen does a scuba tank provide?
A standard scuba tank holds around 80 cubic feet (about 2,260 liters) of compressed air, which is approximately equivalent to 2,000 liters of breathable oxygen at sea level. This amount can provide enough oxygen for an average diver for about 45 minutes to 1 hour, depending on depth and breathing rate.
Why should a filled scuba tank never be left in a hot car for an extended period of time?
Leaving a filled scuba tank in a hot car can cause the air inside to expand as it heats up, increasing pressure and potentially leading to a burst or explosion, posing a safety risk. Additionally, high temperatures can degrade the tank's materials and compromise its integrity, making it unsafe for future use.
