    How Does Pressure and Temperature Affect an Air Bubble's Volume at Sea Depth?

    At depth of 20 m below the surface of the sea, where the temperature is 5.0ºC, a diver exhales an air bubble having a volume of 1 cm3. a. If the surface temperature of the sea is 22.0ºC, what is the volume of the air bubble just before it breaks the surface? (Start hint: pressure beneath the...

    Calculate Extra Gasoline in kg with Density and Expansion Rates

    The density of gasoline is ρ = 0.730×103 kg/m^3 at 0ºC. Its average coefficient of volume expansion is α(sub v) = 9.60×10^-4 (ºC)-1. If 1.00 gallons of gasoline occupies 0.00380 m^3, how many extra kilograms of gasoline would you get if you bought 10.0 gallons of gasoline at 0ºC rather than at...
