Calculate the temperature (°C) at which the volume of the gas become close to zero.
Hints:
1. The temperature of the gas at which the volume is close to zero is obtained by
extrapolation of the best fit straight line to the V≈ 0.
2.
The extrapolation in Excel is carried out by: Right click on the straight line
→From the dropdown menu select Format Trend line → Forecast → backward
→Type 250 in the blank field.
