What if there is not enough water in a cylinder to cover a sample?
then you would have a problem to find out the right amount of volume of the sample that you dropped in the cylinder.
What happens during a phase change as heat is added to a water sample?
As heat is added to a water sample during a phase change, all of that heat goes into changing the phase, say from solid ice, to liquid water, and as a consequence, the TEMPERATURE of the sampleDOES NOT CHANGE.
How many centicubes added to a measuring cylinder of water if the water level rose by 25ml?
15
A water sample has a volume of exactly 12.0000mL How would this volume be recorded if it were measured from a a 50-mL graduated cylinder?
A water sample has a volume of exactly 12.0000mL. This volume would be recorded 12.0mL if it were measured from a 50-mL graduated cylinder.
A nugget of gold is placed in a graduated cylinder that contains 85 mL of water The water level rises to 225 mL after the nugget is added to the cylinder What is the volume of the gold nugget?
145cm cubed
What method is the best way to find the volume of a sample of water?
Use a graduated cylinder and the water displacement method. Pour the sample of water in the graduated cylinder and find its meniscus. That is its volume.
Will density of a liquid increase if parts of the solid sticks out of the water?
No. Density is an intrinsic property and does not depend on the amount or size of the sample. If you are referring to finding the volume of an irregular solid by water displacement, then you will get a very large experimental error if the solid sticks out of the water. The amount of water added to the graduated cylinder initially, must be enough to completely cover the solid, before you place the solid in the cylinder.

A sample of zinc is placed in a graduated cylinder. The initial volume of water= 15.0mL and final volume of water and sample= 24.0mL. Determine the mass of the sample of zinc?

Why is distilled water used to dissolve the detergent sample instead of tap water?
There are impurities and added chemicals in tap water that may alter the sample testing result.
What was the PH trend seen when adding CO2 to the water sample?
As CO2 is added to water, the pH usually decreases.
What happens during a phase change as heat is added to a water sample?
As heat is added to a water sample during a phase change, all of that heat goes into changing the phase, say from solid ice, to liquid water, and as a consequence, the TEMPERATURE of the sampleDOES NOT CHANGE.

What is the difference between assay on as is basis and assay on anhydrous basis?
assay on as is basis includes the sample+water content+residual solvents+others. but assay on as is basis takes water content into account that means weight of the water present in the sample will be added in weighing the sample quantity of API required.
A sample of lead is found to have a mass of 32.6 A graduated cylinder contains 2.8 mL of water After the lead sample is added to the cylinder the water level reads 5.7 mL Calculate the density of lead?
The difference in water levels is equal to the volume of the sample [5.7 mL - 2.8 mL = 2.9 mL]. The density is mass/volume. Mass = 32.6 g [I'm assuming grams]. (32.6 g)/(2.9 mL) = 11.24 g/mL A reference check finds lead density at 11.34 g/cm³ near room temperature (wikipedia). A cubic centimeter and a milliliter have the same volume.
