Question 1.
The equation of the line is given as y = 0.28503x + 93.921, where 'y' is the pressure in kPa and 'x' is the temperature in oC.
Here, the y-intercept is 93.921, which indicates "The value of 'y' at x = 0"
i.e. The physical value of the intercept (93.921 kPa) tells you "the value of pressure (in kPa) at 0 oC temperature".

1. Student obtained the value 26.5 for the slope of the fitting straight line on the graph P=const*(1/V) representing the experimental data from the water-based 2-tube apparatus. The experiment was conducted at temperature 22 degree Celsius. What value for the ideal gas constant follows from the obtained slope? The additional necessary data are provided in the text.2. In the pressure versus temperature experiment, the graph P=const*(T+273.15) of the experimental data (temperature in degree Celsius) was fitted with a straight line,...

Water vapor accounts for part of the gas volume and S8 lle volum u sued must be corrected for the water vapor present. The vapor pressure of the water depends on temperature and the vapor pressure of water (PH,o) at different temperatures can be found in Table 1. If a Ph,o value at a particular temperature is not usted in the table, then it has to be found through the interpolation method from...

1) Use the Matlab function polyfit to curve fit the saturation pressure versus temperature data along the vaporization line for water in the table below with a polynomial of degree n. The Matlab function polyval may be used to evaluate the polynomial at any point. Compare the saturation pressure as calculated by the polynomial with the data given in the table and observe what happens as the degree of the polynomial n is increased. Tabulate...
