Some amount of nitrogen occupies 20.0 m3 at a gauge pressure of 224 kPa. Find the gauge pressure when its volume is 30.0 m3. O 161 kPa O 101 kPa 217 kPa O 116 kPa

If 86.5 moles of an ideal gas occupies 0.0275 cubic meters at 39.5 °C, what is the pressure of the gas? pressure: Pa

7) A gas has a volume of 5 cubic feet and a gauge pressure of 3 atm at a temperature 40 degrees Fahrenheit.The volume is decrease to 2 cubic feet and the temperature is raised to 140 degrees Fahrenheit.What is the new gauge pressure in atm’s?

A basketball is pressurized to a gauge pressure of PG = 55 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. Calculate the absolute pressure inside the basketball in kPa when it is at the surface.  Write an equation for the pressure difference ΔP between the inside and outside of the ball when it is submerged a distance y below the surface of the water.  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.
