The atmosphere of the planet Mars is 95.3% carbon dioxide (CO?) and about 0.03% water vapour. The atmospheric pressure is only about 600 Pa, and the surface temperature varies from?30°C to ?100°C. The polar ice caps contain both CO2 ice and water ice. Could there be liquid CO2 on the surface of Mars? Could there be ?liquid water? Why or why not?
Solution 51E Step 1 of 2: In the given problem, they have provided the atmospheric pressure and temperature on the surface of planet Mars. We need to find, whether the components of an atmosphere that is, carbon dioxide and water can exist in liquid phase on the surface of mars. Given data, Atmospheric pressure, P =a600 Pa Temperature range, T= -30 cto -100 c 0 To convert temperature from Celsius to Kelvin scale, TK= T C + 273.15 T=(-30+ 273.15)to( -100+ 273.15) T=243.15 k to 173.15 k
