- what is expected it to take more or less energy to promote of solid propanone to liquid propanone at the melting point when compared to promoting same amount of liquid propanone to vapor at the boiling point. Explain please!A right circular cone of base radius R, height H, and known density ρs floats base down in a liquid of unknown density ρf . A height h of the cone is above the liquid surface. Derive a formula for ρf in terms of ρs, R, and h/H, simplifying it algebraically to the greatest possible extent. [Recall Archimedes’ principle, stated in the preceding problem, and note that the volume of a cone equals (base area)(height)/3.]5.Measures to observe when measuring viscous liquids include the following, with exception ofa.Use of silicone treated glassware for smaller volume of liquidsb.Pouring from bottle that is not completely filledc.When pouring, do not allow the liquid to run down the inside surface of the graduatesd.Drainage time is longer6.Most accurate balance to use for pharmaceutical analysisa.Household scaleb.Top loading balancec.Analytical balanceTriple beam balance
