Solution

Absolute zero is C. The temperature at which molecules stop moving. This is the lowest possible temperature where nothing could be colder and no heat energy remains in a substance. It is zero on the Kelvin scale, or -273.15 degrees Celsius.

Towards the end of the 1600's the French physicist Guilluame Amontons noted that for any trapped gas whose volume and mass are held constant, the rise in temperature produces the same increase in pressure. The experimental values gave:Pressure = slope × Temperature (in °C) + intercepta linear relationship between pressure and temperature. Several years later, in 1779 Joseph Lambert defined absolute zero as the temperature at which the pressure of a gas becomes zero when a plot of gas pressure versus temperature is extrapolated to Pgas = 0. (See L. H. Adcock, J. Chem. Educ., 75, 1567-1568 (1998) for additional explanation.) How would the value of absolute zero defined in this manner theoretically compare to the value based on Charles' law? How do these theoretical values compare to what your data for Charles' Law says is absolute zero?
