What happened to the kinetic energy of the particles in a sample of gas as the temperature of the sample increase?
The average Kinetic energy of the atoms in the sample will increase as the sample is heated.
What sample most likely has the lowest density?
Liquid mercury
If the temperature is increased What happens to the partial pressure of oxygen in a sample of air?
In a sample of air, an increase in temperature will result in an increase in the partial pressure of oxygen.
The mass of a sample is 0.001580 g The number of significant figures in this measurement is?
That measurement has 4 significant figures. It could also be stated as 1.580 x 10^-3.
What happens to a fixed sample of gas when its temperature changes?
If a fixed sample of gas has a change of temperature pressure would increase.
What is in process sampling?
In-process sample is considered as, in order to move forward from one process step to the next. here is an example: During the process after mixing of a solution the nd Condu. measurement should be X.X to X.X before one can start to transfer the solution to next step. To draw some volume to test the pH and Condu. sample would be considered in-process sample measurement.
Best measurement for mass of a mineral sample?
Balance
How does a parameter and a statistic differ?
A parameter is a numerical measurement of a population; a statistic is a numerical measurement of a sample.
A droplet of pure mercury has a density of 13.6 gcm3. What is the density of a sample of pure mercury that is 10 times as large as the droplet?
Density is weight per volume. It does not change because the size of the specimen changed. The total weight will increase, but not the density.
Calculating Mercury in Mercury oxide by gravimetric analysis?
First take the mercury oxide and heat it so that it decomposes completely. This will drive off the oxygen gas and leave you with elemental mercury. Record the exact mass of the mercury that you have left at the end of the reaction. Divide this mass of mercury by the original mass of your mercury oxide sample and multiply by 100. This will be the percent mercury by mass in your original sample.
What happened to the kinetic energy of the particles in a sample of gas as the temperature of the sample increase?
The average Kinetic energy of the atoms in the sample will increase as the sample is heated.
What is the purpose of the blank?
Blank Sample in Spectrophotometry is used to measure the absorbance of light without sample. It is subtracted from the total absorbance for measurement of Absorbance from a sample's absorbance.
What sample most likely has the lowest density?
Liquid mercury
What do you mean by decimation in digital processing?
Decimation in digital processing is the process wherein sampling rate of a signal is reduced. An increase in sample rate is complementary to interpolation.
A discrete distribution is usually the result of?
a. a measurement. b. a count.c. a small sample. d. a small probability.
Sample of salary increase letter?
yes
What is the purpose of blank samples?
Blank samples are used to establish a baseline measurement of background contamination in an analysis. By analyzing a blank sample containing no target analytes, researchers can identify and account for any background signals or contamination that may affect the accuracy of their results.
