What is the approximate mass of the air in our 10 m × 12 m × 4 m physics lab? The density of air is 1000 g/cm3.
Convert density to kg/m^3
At 26.0 m below the surface of the sea (density = 1 025 kg/m3), where the temperature is 5.00°C, a diver exhales an air bubble having a volume of 1.10 cm3. If the surface temperature of the sea is 20.0°C, what is the volume of the bubble just before it breaks the surface in centimeters?
