Answer #1

Charles' Law states that the volume of a gas is proportional to its temperature.

We can write this law in terms of a constant of proportionality

Looking at this law, we might be misled to think that at , .

However, Charles' Law is only applicable when the motion of the molecules of gas is sufficient to prevent electrostatic attraction and Van der Waal's Forces between them. In other words, Charles' Law is best suited for describing the behaviour of a hot, rarefied gas and not for gases at low temperatures.

Therefore, a gas' volume need to be zero at absolute zero.

If the temperature of 1 mL of air at 1 atm and 0 degrees C is raised to 100 degrees C at the same pressure, the volume becomes 1.3671 mL. Calculate the value of absolute zero for a thermometer using air, assuming that the pressure-volume porduct is linear with absolute temperature even at 1 atm. Compare your result with the ice point temperature in Table 2.3. Ice point temperature = 273.15K
