If the pump is a cylinder of length 16.0 in. with a cross-sectional area of 3.00 in.2, how far down must the piston be pushed before air will flow into the tire? Assume the temperature is constant. Answer must be in inches
A bicycle tire has a pressure of 7.05 x 105 Pa at a temperature of 17°C and contains 2.00 L of gas.
A bicycle tire has a pressure of 7.05 x 105 Pa at a temperature of 17°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 120 cm3 at atmospheric pressure and at the temperature of the tire? Assume tire temperature and volume remain constant.
