According to Charles law the air pressure in a closed container should vary linearly with clesius temperature. Suppose that the following pressures and temperatures are measured for a particular container
a)Plot the data accurately.Then line up a ruler so that the line you would draw using it will 'fit' the data as closely as possible. Draw the line

needs a graph
sir will u please explain detail
needs a graph paper sheet to plot these points. i need a camera to take picture and paste it here

See diagram.
Plot the points on a two-dimensional graph. You can take the proper graph sheet and plot them like I did.
Then draw a line that is very close to all points. touch the points - as many as you can to draw. Extend the line to Pressure axis.
I see that it meets Pressure axis at 14 units. P Intercept = 14 units
Now find slope. Take two points on the straight line. Find the increase in pressure and increase in temperature between them.
Slope = increase in pressure / increase in temperature = (80-14)/(1000- 0)
= 0.066 units
P = 0.066 T + 14 units
