Question

How can I make this graph that extends through the Y axis given these points: (6, 124.86) (94,148.1) and (6,85.92) (93,148.1) and what is the value of the absolute zero of both lines?

To find the value of absolute zero for each trial, connect the two points that you have plotted and by using a ruler draw a straight line through these points, extrapolating this line to the y-axis (line must extend to 0 mL).

Explanation / Answer

Note that there will be two different XY plots

Case I: Consider two points (6,124.86), (94,148.1)

Mark these points and draw a line passing through these two points

Note: X axis denotes temperature and range is -300 to 110 (given)

Thus, X value should be -300 to left side of origin and 110 to the right side of origin(you can take 1cm = 50units on X)

For Y you can take range from 0 to maximum of 150 (148.1 is max you can take 1cm = 15 units on Y),

Once you draw the line joining these two points (6,124.86), (94,148.1)

Find the value of X for which line intersects X axis as on X axis Y=0. That will be absolute 0 temperature value (lets say Y=148.1 when X=94 is given. Similary, when Y=0 find X. if X is -273 when Y = 0 then absolute 0 value is -273)

Case II: Repeat the same for other set of values (6, 85.92), (93,148.1)
