What else can I help you with?
What if there is not enough water in a cylinder to cover a sample?
If there is not enough water to fully cover a sample in a cylinder, the sample may not be accurately submerged or displaced, leading to inaccurate volume measurements. It's important to ensure that the sample is fully covered to obtain precise readings in experiments involving displacement of fluids.
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 a hot water cylinder tray?
A tray place under the cylinder designed to catch any water that may leak and also available with an overflow to take the water away to a drain or outside, preventing structural damage caused by water leaks.
How many centicubes added to a measuring cylinder of water if the water level rose by 25ml?
One centicube is equal to 1 cm^3. Therefore, you would need to add 25 centicubes to the measuring cylinder of water if the water level rose by 25 ml.
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?
The volume of 12.0000 mL would be recorded as 12.00 mL when measured from a 50-mL graduated cylinder because the cylinder has markings in increments of 1 mL. It is standard practice to record the volume to two decimal places for greater accuracy.
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.
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.
How do you dilute urine samples?
To dilute a urine sample, you can mix it with distilled water or a diluent solution in a clean container. The amount of diluent added will depend on the desired dilution ratio. Make sure to mix the sample thoroughly before testing.
What was the PH trend seen when adding CO2 to the water sample?
As CO2 is added to water, the pH usually decreases.
How do you remove water from the gas sample before ingection to GC?
One common method to remove water from a gas sample before injection into a gas chromatograph (GC) is to use a gas drying tube filled with a desiccant such as molecular sieves or silica gel. The gas sample is passed through the drying tube, which absorbs the water moisture present in the sample. Another method is to use a water trap in the gas line to condense and collect the water vapor before the sample enters the GC inlet.
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.
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.
What tool would you use to most accurately measure the volume of a water sample from a river?
A graduated cylinder would be the most accurate tool for measuring the volume of a water sample from a river. This tool allows for precise measurements of liquid volumes by reading the markings on the cylinder and is commonly used in laboratories for this purpose.
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.
What can be used to mesure the volume of a solid object?
You can measure the volume of a solid object using a graduated cylinder and the water displacement method. Simply fill the graduated cylinder with water to a certain level, then place the solid object in the water and measure the increase in volume. The difference in volume before and after the object is added will give you the volume of the object.
