What is the pressure of the gas in the cylinder, in kPa (kiloPascal)? h = 0.620 m, Pmercury = 13,600 kg/m3, 1.0 atm = 1.00 x 105 Pa = 100 kPa, and g = 10.0 m/s?. Your answer needs to have 3 significant figures, including the negative sign in your answer if needed. Do not include the positive sign if the answer is positive. No unit is needed in your answer, it is already given in the question statement. Mercury. p = 13,600 kg/m² Pen

A basketball is pressurized to a gauge pressure of PG = 75 kPa when at the surface of a swimming pool. (Patm = 101 kPa). The ball is then submerged in the pool of water which has a density ρ = 1000 kg/m3. Assume the ball does not change in mass, temperature, or volume as it is submerged. a) Calculate the absolute pressure inside the basketball in kPa when it is at the surface. b) Solve the pressure equation for the depth (in meters) at which the pressure difference between the inside and outside of the ball will become zero. At this depth the pressure inside the basketball is the same as the pressure outside the ball. c) At what depth, in meters, would the pressure difference between the inside and outside of the ball be zero if the ball were submerged in mercury (ρ = 13,500 kg/m3) instead of in water?
Some amount of oxygen occupies 500 in at an absolute pressure 40 lb/in (psi). What should be the corresponding volume at an absolute pressure of 100 psi? O 220 in n 270 in O 200 in3 170 in aock amy
What is the cause of air pressure? Why does the pressure a fluid exerts on the walls of its container decrease when the fluid starts to flow through the container (e.g. a piece of tubing)? Why is it impossible to pull a fluid? What does it mean to "entrain a fluid" into a flow? When the gauge on a cylinder of gas reads zero, is the cylinder actually empty? Explain.
If you decrease the volume of a gas to 1/2 its original volume, how much bigger or smaller is the pressure of the gas? If you increase the volume to 6 times its original volume, how much bigger or smaller will be the pressure of the gas?
