Julia pours three samples of water She leaves one sample on the counter top another in the freezer one sample outside in the sun The next day each sample of water is most likely to have the same what?
Julia pours three samples of water she leaves one sample on the counter top another in the freezer and leaves one sample outside in the sun the next day each sample of water is most likely to have the same (A)temperature (B) state of matter (C) boiling point
What is meant by the term aliquot in chemistry?
Aliquot is a known part extracted from a volume of sample.
How could you predicd if a block of plastic will float in water?
The block of plastic must be less dense than the water in which it will be placed in order to float. Density is equal to mass over volume (D=m/v), so you could calculate the density of the block of plastic and of a sample of the water by dividing the weight of each sample by the respective volume of each sample. If the density of the plastic is less than the density of the water, it floats! A hint: the maximum density of fresh water occurs at 4 C∘and is equal to 1 gram per 1 milliliter. When a solute - such as salt - is added, the density of water will decrease.
How many moles of specified particles are present in a sample of N'O if each sample weighs 7.00 g?

Measurement of the amount of space that matter occupies?
Volume is a measure of how much space a sample of matter occupies. the SI unit of volume is m3 .
How do you produce 3 solutions of sugar in water?
Measure three different masses of sugar and add enough water to each sample to equal the same volume of water, such as 100mL or 1000mL. Do not just simply add 100 or 1000mL. You add water to each sample up to the volume you want. So you actually will not add the same amount of water to each sample.
How much greater is the volume of a cube when the length of each edge is multiplied by 5?
Sample A: cube of side 2, volume 2 x 2 x 2 = 8 Sample B: cube of side 10, volume 10 x 10 x 10 = 1000 Volume has increased by a factor of 125 ie 53 which is what we would expect.

What would you use to measure sea water?
A unit of volume such as a litre.
Does each sample have measurable mass?
The answer depends on sample of WHAT!
Is the density the same or different for each volume of water?
If it is from the same sample, yes. The density of water does vary slightly depending on temperature and any dissolved solutes.
Each individual outcome of an experiment is called the sample space or sample point?
sample space
Is a stratified sample a probabilty sample?
Within each stratum it is, but overall, it is not.
If you have a 1.0cm3 sample of lead and a 1.0cm3 sample of glass You drop each in separate beakers of water How do the volumes of water displaced by each sample compare?
They're the same.
