Answer to Question 3

Back

Use the formula:

p1V1 = p2V2

T1        T2

Put in the numbers:

3.03 105 Pa 3.0 10-3 m3 = 1.01 105 Pa V

283K                                           293 K

Rearranging:

V = 3.03 105 Pa 3.0 10-3 m3  293 K

283 K 1.01 105 Pa

 

 

V = 9.32 10-3 m3 = 9.32 litres (which would mean that they could burst).

 

Divers have to be very careful when coming to the surface.  If the pressure reduces too quickly, nitrogen gas can form small bubbles in the blood that are at best extremely painful (the diver doubles up, hence "the bends").  At worst it can be fatal.
