How do you frozen plant sample in liquid nitrogen?
To freeze a plant sample in liquid nitrogen, first place the sample in a container suitable for cryogenic temperatures. Submerge the sample in liquid nitrogen gradually to prevent splashing. Ensure the sample is completely frozen before transferring it to a long-term storage container for storage at ultra-low temperatures.
Why is the sample needed to be heated over a Bunsen burner before heating in a muffle furnace?
Heating the sample over a Bunsen burner helps remove any moisture or volatile impurities that may be present on the surface of the sample. This preheating step ensures that the sample is clean and free of contaminants before being subjected to high temperatures in the muffle furnace, helping to prevent unwanted reactions or interference with the analysis.
How do you make a pure sample of boron?
One method to obtain a pure sample of boron is by reducing boron oxide with a metal at high temperatures. Another method is through the electrolysis of molten boron compounds. Purification processes like sublimation and distillation may also be used to achieve a high-purity boron sample.
Based on Reference Table H which sample has the highest vapor pressure?
The sample with the highest vapor pressure will be the one with the highest temperature listed in Reference Table H. Generally, higher temperatures result in higher vapor pressures for a substance.
As the temperature of a radioactive sample increases the rate of the nuclear decay?
The rate of nuclear decay increases as the temperature of a radioactive sample increases. This is due to the increased kinetic energy of the nuclei at higher temperatures, which facilitates interactions that lead to nuclear decay.
Difference between random sample and convenience sample?
random sample is a big sample and convenience sample is small sample
What is the apparatus being used in Linds method?
The apparatus used in Linds method is a crucible and lid, which are used to heat a sample to high temperatures in order to determine the moisture and volatile content.
How do you make a pure sample of helium?
A pure sample of helium can be obtained by extracting it from natural gas through a process called fractional distillation. This involves cooling the natural gas to very low temperatures, which causes the various components to condense at different points. By isolating the helium gas at the corresponding temperature, a pure sample can be obtained.
What is the difference between sample and sample size?
a sample is a sample sized piece given... a sample size is the amount given in one sample
What is subset of a population called?
A Sample
When can refrigeration not applicable to preserve sample for enzymatic assay?
Refrigeration is not applicable to preserve sample for enzymatic assay because enzymes may lose their activity at extremely low temperatures as well. This may account for storing enzymes at 5° C or below without affecting the enzymatic activity permanently. (Anubhav, 2012)
What is a biased sample?
A biased sample is a sample that is not random. A biased sample will skew the research because the sample does not represent the population.
