An air/gasoline vapor mix in an automobile cylinder has an initial temperature of 178 ∘C and a volume of 12.1 cm3. If the mixture is heated to 587 ∘C with the pressure and amount held constant, what will be the final volume of the gas in cubic centimeters?

The reservoir in Figure contains water and immiscible oil at a temperature of 20 ° C. What is the height h in centimeters if the density of the oil is 898 kg / m3?

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.

A large room contains a volume of air of Va = 15 m3 at a temperature of Ta = 53° F. It also contains a bathtub holding a volume of water of Vw = 0.56 m3 at a temperature of Tw = 101° F.   If the density of the air at Ta is ρa = 1.25 kg/m3, calculate the mass of air in the room in kilograms.  If the density of the water at Tw is ρw = 1000 kg/m3, calculate the mass of the water in the bathtub in kilograms.  Take the room and water as an isolated system. Write an equation for the equilibrium temperature of the system T in terms of ma, Ta, mw, Tw, and the specific heat capacity of the air ca and the water cw.
