Unformatted text preview: thermodynamically explain Darwins frustrations. 3. Water at 27C can exist in different phases dependent upon the pressure. Give the approximate pressure range in kPa for water being in each one of the three phases vapor, liquid or solid. 4. If density of ice is 920 kg/m 3 , find the pressure at the bottom of a 1000 m thick ice cap on the north pole. What is the melting temperature at that pressure? (Take the density of ice to be 920 kg/m 3 , also recall P total = P atm + P ) 5. Sublimation occurs by: a) absorption of energy b.) release of energy c.) None of these Explain your answer! 6. Condensation occurs by: a) absorption of energy b.) release of energy c.) None of these Explain your answer! Due Wednesday June 16, 2010 10:00AM References: 1.
