- Problem 13: A bicycle tire has a pressure of 6.8 × 105 Pa at a temperature of 15°C and contains 2.00 L of gas. What will its pressure be, in pascals, if you let out an amount of air that has a volume of 115 cm3 at atmospheric pressure and at the temperature of the tire? Assume tire temperature and volume remain constant.arrow_forwardA diver is at 5 meter depth in a fresh water lake. At that depth, the temperature is 15◦C. The pressure in the water at a depth d is given by p(d) = psurface + ρgd, where ρ is the liquid density, and g = 9.81m s−2is the gravitational constant.(a) The diver releases an air bubble of 1cm diameter. What is the diameter of the bubble when it reaches the surface where the temperature is 20◦C?Assume that the bubble temperature is always the same as the surroundingwater.(b) The diver stayed 1h at a 5m depth. The pressure in the diving tank went down from 250 bars to 50 bars. We assume that the volume of the lungs is 5L. Assuming that the water temperature is also 15◦C, how long could the diver have stayed underwater at 20m depth using the same amount of air?(c) The diver is at 5m depth and decides to surface.
