A scuba diver has his lungs filled to half capacity (3 liters) when 10 m below the surface. If the diver holds his breath while quietly rising to the surface, what will the volume of the lungs be (in liters) at the surface? Assume the temperature is the same at all depths. (The density of water is 1.0x103 kg/m3

A weather balloon rises through the atmosphere, its volume expanding from 4.9 m3 to 14 m3 as the temperature drops from 21 ∘C to -10 ∘C. If the initial gas pressure inside the balloon is 1.0 atmatm, what is the final pressure?

A bubble having a diameter of 27 cm is re- leased from a depth of 4.6 m from the bottom of a swimming pool. The temperature of the water at the surface is 18°C, whereas it is 17°C at the point of release. What will the diameter of the bubble be when it reaches the surface? The acceleration of gravity is 9.8 m/s² and the density of water is 1000 kg/m³. Answer in units of cm. Answer in units of cm.

On the surface of a hypothetical planet X, the atmospheric pressure is 4.25 x 106 Pa, and the temperature is 707 K. On the earth's surface the atmospheric pressure is 1.00 x 105 Pa, while the surface temperature can reach 320 K. These data imply that the planet X has a "thicker" atmosphere at its surface than does the earth, which means that the number of molecules per unit volume (N/V) is greater on the surface of planet X than on the earth. Find the ratio (N/V)X/(N/V)Earth.
