Question

pressure temperature relationship in gases.
this is the data

8) the data that you have collected can also be used to determine the value for absolute zero on the Celsius temperature scale. instead of plotting pressure versus Kelvin temperature like we did above, this time you will plot Celsius temperature on the y-axis and pressureon x-axis. since absolute zero is the temperature at which the pressure theoretically becomes equal to zero , the temperature where plotted line intercepts the y-axis should be the Celsius temperature value for absolute zero. you can use the data you collected in this experiment to determine a value for absolute zero.
a) on a sheet of gragh paper plot the pressure on the x-axis making sure that the starting pressure is zero.
b) plot the Celsius temperature on the y-axis. a gragh of temperature (C) vs pressure is now displayed.
c) draw the best straight line that fits the data points ensuring that there is equal spacing between the points above the line and below it.
d) make sure the line passes through the y-axis of the gragh.
e) determine the value of the point on the y-axis where the line passes through it. that is the in centigrade

Explanation / Answer

the given data point are plotted with pressure on x axis and temperatrue on y- axis. The plot is shown below

when x=0, y=307.7 deg.c
