a million. There are 2 incorrect statements: B by using fact all molecules are in action except the termperature is 0oK. C by using fact there is gravitational allure between any 2 lots. examine Newton's regulation of Gravitation: F = G*m1*m2*/r^2. it fairly is a small allure, even though it fairly is inaccurate to declare there is not any allure. 2. tension exists once you confine gasoline to a small area. in case you provide it extra volume to enhance in, the strain decreases. 3. Convert all to mm Hg O2: 0.250 atm*7.6 mm Hg/a million atm = a million.9 mm Hg N2: 385 mm Hg Ne: P3 comprehensive: 825 torr = 825 mm Hg 825 mm Hg = (a million.9 + 385 + P3) mm Hg P3 = (825 - a million.9 - 385) mm Hg = 438 mm Hg

C. Contracts
I think I remember that water has its greatest density at 4 degrees Celsius.
