Question

Calculate the value of absolute temprature from Charles law?

Answer 1

Answer:

Absolute zero

The absolute zero temperature is the lowest possible temperature. At such an extreme temperature, molecular motions like vibrational, translational, rotational ceases. And its value is −273.15 °C or 0 K.

Charles' law

Charles' law is an empirical law that states when the pressure of a fixed amount of gas is constant, the volume is directly proportional to its temperature. In mathematical terms, V = kT.

Relation between both

Both are related by the graph. It is a volume versus temperature (in °C) graph plotted at constant pressure.

As per Charles' law, when the temperature of an ideal gas decreases, its volume also decreases. Volume approaches zero at t = −273.15 °C, the x-intercept of the graph. If we extrapolate the line below that temperature, it will give negative volume, which is nonsense. Thus, −273.15 °C is the lowest possible temperature.

We can also prove this using the equation of Charles' law. It is V = kT. Here, T is the temperature expressed in the kelvin. V is zero only when T = 0 K, which is −273.15 °C.
