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 m ...continues

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.

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 ...continues
