- Titans exosphere has a temperature of about 174 K. What is the thermal speed of hydrogen (in km/s) in Titans exosphere ? The mass of a hydrogen atom is 1.67 x10-27kg and Boltzmann's constant is k=1.38 x10-23 Joule/KelvinWithout the greenhouse effect, Earth's average surface temperature would be about 250 K. With the greenhouse effect, it is some 40 K higher. Use this information and Stefan's law to calculate the fraction of infrared radiation leaving Earth's surface that is absorbed by greenhouse gases in the atmosphere___ nm
- Saturn is even further at 1434X109m from the sun. Calculate the approximate strength of the greenhouse effect on Jupiter. The observed surface temperature is 133K, the albedo is 0.47, the solar constant is 15W/m2.Numerous surface features on Venus can be seen in Earth- based images made in the ultraviolet part of the spectrum. (T/F)Titan's exosphere has a temperature of about 218 K. What is the thermal speed of hydrogen (in km/s) in Titan's exosphere? The mass of a hydrogen atom is 1.67 × 10-27 kg and Boltzmann's constant is k = 1.38 × 10-23 Joule/Kelvin.
