Question
Part C 1c. The solid is not completely submerged in the water. Will this technique error increase, decrease, or have no effect on the reported density of the solid Explain: Part C 2 modified. Suppose that several drops of water cling to the inner wall of the graduated cylinder, away and above the meniscus, (because the cylinder is dirty). Will this technique error increase, decrease, or have no effect on the reported density of water? Explain: Part C 3 modified. The chemist records the mass of the 10 mL graduated cylinder(__g), fills the grad with 5.00 mL of unknown liguid, records the liquid volume (guess in hundredths). The unknown liquid is volatile and some evaporates before a mass can be measured- recorded. Will the reported density of the liquid be too high, too low, or unaffected? Explain:Explanation / Answer
1c) There will be an increase on the reported density of the solid
Density of the solid = Mass of the solid /Volume of water displaced when submerged into water.
If the solid is not fully submerged, then the volume of water displaced will be lesser than the actual volume.
and hence the reported density will be more than the actual density
C2 ) No effect on the reported density of water.
The drops of water clings to the inner walls of the cylinder away and above the meniscus will not affect the volume. Mass of the given volume of water is calculated by substracting mass of the cylinder from mass of cylinder plus water. Therefore, the mass of water cling to the innerwalls will not be added to the actual mass of water. Hence density will not be affected.
C3) Reported density will be too low.
As the liquid is volatile ,the measured mass will be lesser than the actual mass of the liquid. Hence reported density will be lower than the actual density.
