Mixtures of helium and oxygen are used in scuba diving tanks to help prevent "the bends". For a particular dive, 35.0 L of He at 20.5 °C and 1.50 atm and 15.0 L of O2 at 20.5 °C and 1.50 atm were pumped into a tank with a volume of 7.50 L. What is the total pressure (in atm) in the tank at 20.5 °C? a. 3.00 atm
b. 1.50 atm
c. 20.5 atm
d. 7.50 atm

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
