What is experimental material?
Experimental material typically refers to items or substances used in scientific experiments to test hypotheses or theories. These materials can include chemicals, biological samples, equipment, and any other physical components necessary for conducting an experiment. It is important to handle and store experimental materials properly to ensure the accuracy and repeatability of experimental results.
What are the Pros and cons of bomb calorimeter?
Pros: Accurate measurement of energy content in food or fuel samples, precise control over experimental conditions, and reliable results for calculating calorific values. Cons: Expensive equipment, time-consuming process to operate and analyze samples, and limited to measuring only the energy from combustion reactions.
Why do you prepare blank solutions?
Blank solutions are prepared to account for any potential interference or contamination that may affect the accuracy of the experimental results. They provide a baseline measurement to which experimental samples can be compared, helping to ensure that any observed changes are due to the analyte of interest and not other factors.
What is the function of a positive control in an experiment?
A positive control is used in an experiment to ensure that the experimental conditions are capable of producing a positive result. It helps validate the experimental setup and serves as a reference point for comparison with the test samples.
Why do you need a molecular weight ruler alongside your samples during electrophoresis?
A molecular weight ruler uses a sample of fragments of a known size (known as a molecular weight marker) to be placed alongside the experimental and control samples. It helps compare the migration distance of the experimental fragments to the migrating distance of the fragments of a known size that make up the molecular weight marker. Then the scientist can calculate an approx. size of their experimental samples.
What indication do the experimental result give regarding the purity of the samples used?
After a detailed chemical analysis the purity is correctly evaluated.
What is the difference between control samples and test experimental samples?
It calculates the difference between each set of pairs, and analyzes that list of differences. The P value answersthis question: If the median difference in the ... If your samples are small and there are no tied ranks, Prism calculates an ... The whole point of using a paired test is to control for experimental.
What is the difference between experimental replicates and experimental controls?
Replicates are "repeat" samples under a given condition.

These materials can include chemicals, biological samples, equipment, and any other physical components necessary for conducting an experiment. It is important to handle and store experimental materials properly to ensure the accuracy and repeatability of experimental results.
Why is it important to determine the melting ranges of the impure and recrystallized samples of vanillin?
The melting point is an indication of purity.
What are the Pros and cons of bomb calorimeter?
Pros: Accurate measurement of energy content in food or fuel samples, precise control over experimental conditions, and reliable results for calculating calorific values. Cons: Expensive equipment, time-consuming process to operate and analyze samples, and limited to measuring only the energy from combustion reactions.
What is the use of bioassay test panels?
Bioassay test panels includes a tested series of frequently requested samples or disease state samples with healthy controls to do comparitive experimental research.
Why quasi experimental design are high in external validity?
Quasi-experimental designs involve studying real-world settings and conditions, which increases the generalizability of the findings to other similar contexts. The use of diverse samples and settings in quasi-experimental designs enhances the external validity of the results by allowing researchers to draw conclusions that can be applied to a broader population. Additionally, quasi-experimental designs often involve manipulating independent variables in natural settings, making it easier to extrapolate the findings to real-life situations.
