Plot the experimental data given above and draw the best straight line. Extend the line to the point where the volume is zero. This is the experimental value for absolute zero in degrees Celsius. Remember to label your axes and to give your graph a title. Attach your graph to this question sheet. Experimental value for absolute zero -

Answer 1

V = 0.0079x + 2.2061 Temperature (°C) Volume (L) 100 2.98 80 2.87 2.68 2.53 2.33 2.21 2.07 1.88 Volume (L) Absolute zero = -279 °C (approx.) -350-330-310-290-270-250-230-210 -190 -170 -150 -130-140 -90 -70 -50 -30 -10 10 30 50 70 90 Temperature (°C)

Experimental value for absolute zero = -279 °C
