Question

Prove that temperature can't go beyond - 273°c

Answer 1

according to Charles law at constant pressure, the volume of a fixed mass ofgas is directly proportional to its absolute temperature.
✴️ When a graph is plotted at constant pressure between volume and temperature a straight line is obtained. when the line is extrapolated to lower temperature which represent zero volume. The temperature at which volume becomes zero has been found to be - 273 degree celsius. Charles knew that zero and negative values of volume are not possible physically. therefore, he proposed that - 273 degree Celsius is the lowest possible temperature. It may be noted that this value does not depend upon the nature of gas or pressure at which the experiment is performed........
⏩ ⏩ thus, - 273 degree Celsius is the lowest possible temperature because below this temperature, the volume will become negative.
