1.	State the nature of the graph drawn between volume and temperature at constant pressure. When the graph is extrapolated, at what temperature it meet the temperature axis ?
Answer» Solution :A graph is a straight LINE, when a graph is extra polated it MEETS temperature axis at `-273^(@)C`, this indicates that at constant pressure. The VOLUME of GIVEN mass of gas reduces to ZERO at `-273^(@)C`.
