The diagram shows the variation of volume V of a glass with temperature at the point X is

Answer Details

The correct answer is -273^oC. The diagram shows the variation of volume V of a glass with temperature. We can see that as the temperature approaches -273^oC, the volume of the glass decreases rapidly. This is because at -273^oC, all molecular motion ceases and the glass has zero volume, which is also known as absolute zero. Therefore, point X on the graph represents -273^oC.
