A scuba diver exhales 2.65 L of air while swimming at a depth of 36.30 m where the sum of atmospheric pressure and water pressure is 4.51 atm. By the time this exhaled air rises to the surface, where the pressure is 1.00 atm, what is its volume?

11.9515 liter

Explanation:

Assume constant temperature and ideal gas condition where the product of the volume and pressure is constant.

where P, V are the pressure and volume at 2 different positions, one at the depth of 36.3 m and the other at the surface

So the volume at the surface is 11.9515 liter

r=rho l/a where a is the area, l is the length and rho is resistivity so the greater the area the lesser the resistance thats why the earth pin is thicker bcos current follow the shortest path, so less resistive .
