Analyzing Gas Volume-Temperature Relationship Experiment
The diagram in the figure below shows an experiment to investigate the relationship between volume and temperature of a fixed mass of gas at constant pressure
Explain the functions of:
(i) Concentrated sulphuric acid
(ii) Stirrer
(iii) Which measurements are taken in the above experiment.
(iv) How are the measurements used to verify Charles Law

(0 Ratings)
(i)
- To trap the air column
- To dry the gas
(ii) To ensure uniform temperature of the water bath
(iii)
- Temperature of water as temperature of air column
- Length of the air column as the volume of the column
(iv)
- The graph of length /volume against temperature is plotted
- A straight line graph cutting the temperature axis at (-273K) when it is extrapolated
- Volume directly proportional to the temperature .
In this thought-provoking response, the author's perspective is skillfully backed by an extensive body of comprehensive research and readily available information, offering a well-informed and compelling exploration of the subject matter.
Identify radiation B and provide an explanation for the differing deviations observed in the paths of radiations A and C as they pass through an electric field, as depicted in figure 15.
Determine the frequency of X-rays produced in an X-ray tube with a 12000V acceleration voltage, assuming full energy conversion, using Planck's constant and the charge of an electron.
Name the components labeled A and B in the X-ray tube, explain how altering the potential across P affects X-ray intensity, and describe the cause of the high temperature in the tube during operation.
