Analyze the temperature Vs time graph of water, given below, and answer the following questions. (i) Which region contains all liquids?

(ii) Which region contains all solids?

(iii) Which region contains all gases?

(iv) Which region contains both solid and liquid?

(v) Which region contains both liquid and gas?

•what conclusions can you make about the relationship between the volume of a gas and its temperature? • what conclusions can you make about the relationship between the volume of a gas and its pressure? • what possible variables have you not accounted for? as you did the procedures, is it possible that the atmospheric pressure may have changed? if it did change over the course of your experiment, then how would your results have been affected?
