At constant pressure for a given amount of an ideal gas, will the graph obtained by plotting V vs `t^(@)C` and V vs TK be different ?

Explanation

According to Charles' law V=KT . . .[1]
[at constant pressure for a given mass of a gas]
But T=273+t, hence, V=K(273+t) . . [2]
Both the equation [1] & [2] express equations for straight lines. Equation no [1] represents a straight line passing through the origin. equation no. [2] does not represent a straight line passing through the origin. the plot of V vs t results in a straight line that cuts the V-axis at `0^(@)C`. if this straight line is extrapolated backward, it meets the t-axis at `-273^(@)C`. ltBrgt
From the, above two graphs it is evident that there are no actual defferences between the two graphs, because `-273^(@)C` and 0K express the same temperature.
