On the sunlit surface of Venus...

On the sunlit surface of Venus, the atmospheric pressure is 9.0 x 10 6Pa, and the temperature is 740K. On the earth's surface the atmospheric pressure is 1.0 x 10 5Pa, while the surface temp can reach 320K. These data imply that Venus 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 Venus than on Earth. Find the ratio (N/V)venus / (N/V)earth. The ideal gas law says that for an ideal gas: PV=NkT where P, V, and T are pressure (Pascals), volume(m-3), and temperature(K) respectively, N is the number of molecules, and k is Boltzmann's constant of 1.381 × 10−23 J/K...

Atmospheric Physics

The surface of the sun has a temperature of about 6.0 x 10^3K. This hot gas contains hydrogen atoms (m = 1.67 x 10^-27) find the rms speed of these atoms.

Physics Problems

Short answer questions: Show all your work and show the equations or assumptions you are using. Remember significant figures and units!! 1.

Adiabatic processes

Please assist in understanding these problems: 1a) If the temperature on the surface over land is 310 K, and the temperature at 0.5 km is 305 K, what is the ambient atmospheric lapse rate? If a parcel of air starts to rise at the dry adiabatic lapse rate, what would be the temperature of the parcel at 0.5 km? Is this ambient temperature profile an example of a stable, unstable, or neutral situation? Explain. b) Now consider a rising wet parcel of air. What would be the temperature of this parcel at 0.5 km? Relative to this parcel, is the ambient atmospheric temperature profile described above stable, unstable or neutral? Explain. c) Over the ocean, the temperature at the surface is ... click for more
