(II) A scuba tank is filled with air to a gauge pressure of204 atm when the air temperature is 29°C. A diver then jumpsinto the ocean and, after a short time on the ocean surface,checks the tank’s gauge pressure and finds that it is only191 atm. Assuming the diver has inhaled a negligible amountof air from the tank, what is the temperature of the oceanwater?

(a) The pressure gauge on a tank registers the gauge pressure, which is the difference between the interior pressure and exterior pressure. When the tank is full of oxygen (O2), it contains 15.0 kg of the gas at a gauge pressure of 35.0 atm. Determine the mass of oxygen that has been withdrawn from the tank when the pressure reading is 17.6 atm. Assume the temperature of the tank remains constant.

(6) There is a cylindrical container with a piston with diameter d: volume to change. Sitting on top of that piston is a m = the diatomic gas is T 4.67cm which allows the 6.62kg block. The temperature of 382K and there are N 1.45 x 1023 molecules. || (a) What is the gauge pressure of the gas inside the container? (b) What is the volume of this container in cm³? (c) What is the mean free path of a molecule in this container? (d) When the block is remo sure matches external air pressure. How much distance will the piston move during this expansion? (e) What is the work done on this gas by the surroundings while the piston moves to its new position? noved, the gas will expand isothermally until the internal pres-
