Question

A dive tank is designed and built to be safe if the difference between the pressure inside the tank and the pressure outside the tank does not exceed 12 atm. A diver has the tank filled at the dive store at a temperature of 20o C to a pressure of 10 atm. The diver places the tank into his car and parks the car in the sun where the temperature of the gas in the tank increases to 60o C. Is the tank safe at this temperature?

Answer 1

(P1/T1) = (P2/T2)
Substitute and solve for P2, then compare with p1.

Answer 2

calculate the wavelength of a 0.245 kg baseball thrown at a speed of 40.m/s
