Escape velocity is (vescape = 2 G Msun /Rsun) of 620 km/s to leave from the Sun’s surface. When the Sun becomes a red giant, what will the escape velocity be when it is 50 times larger, with a mass of only 90% what it has today?
What will the escape velocity be when the Sun becomes an AGB star with a radius 200 times greater and a mass only 70% of today?
Thanks.

Use henry's law and the solubilities given below to calculate the total volume of nitrogen and oxygen gas that should bubble out of 1.7 l of water upon warming from 25 ˚c to 50 ˚c. assume that the water is initially saturated with nitrogen and oxygen gas at 25 ˚c and a total pressure of 1.0 atm. assume that the gas bubbles out at a temperature of 50 ˚c. the solubility of oxygen gas at 50 ˚c is 27.8 mg/l at an oxygen pressure of 1.00 atm. the solubility of nitrogen gas at 50 ˚c is 14.6 mg/l at a nitrogen pressure of 1.00 atm. assume that the air above the water contains an oxygen partial pressure of 0.21 atm and a nitrogen partial pressure of 0.78 atm.
