WebMar 20, 2015 · Boiling Point Depends on Pressure. We all know that the boiling point of water is 100 degree Centigrade. But this statement is hardly sufficient. We should add that this is the boiling point at sea-level; in other words, under normal conditions. If we climb a mountain, and so obtain a reduced atmospheric pressure, boiling point will be less ... WebThe normal boiling point of a liquid is defined as its boiling point when surrounding pressure is equal to 1 atm (101.3 kPa). Figure 10.24 shows the variation in vapor pressure with temperature for several different substances. WebIts normal boiling point is 80.1°C 10. A mass of CaCl2 , when dissolved in 100.00 g of water, gives an expected freezing point of -5.0°C. What mass of glucose would give the same result? Answers 1) f =kf•m•i=(1.86˚C/m)(1.00m)(3)= -5.58˚C 2) Bp=100.000˚C+[(0.222m)(.513°C/m)(1)] = 100.114˚C mouthwash in chinese japanese inuit
