chem asked:


11L of O2 at 25C and 1 atm were pumped into a 3L scuba tank at 25C. Calculate the total pressure in the tank.

Chem C asked:


The pressure in the cabin of an aircraft is less than atmospheric pressure. Scuba divers are advised not to travel by air for at least 24 hours after a dive. Explain what they might experience if they ignore this advice.

answer correctly and u get 10 points

When people go scuba diving they take a gas tank full of gases. What gases are contained in the tank? Estimate the weight of gas present in a full scuba tank?

Volume = 11 L

P = 170 atm

in scuba diving?

me2 asked:


He takes it to a depth of 25 M where the pressure is 3.5 atm and the temp is 18 degrees C what’s the volume of the balloon at that depth?

sunshine1616 asked:


why wouldn’t the pressure squash the diver? answering this 2nd question would be easier if you think about the reason a person on land is not squashed by one atmosphere of pressure. thanks for the help. this is for school.

kiki keeks asked:

helpp don’t understand pressure, volume and temeperature relation

Lucas B asked:


hello, im doing a chem assignment.

why should a scuba diver NOT take a hot shower after a really DEEP dive??

it has something to do with air bubbles dissolving in cooler water. like when u have a cold class of water warming to room temperature… air bubbles form! how does this relate to hot showers after DEEP dives?

thank you very much for your help
