The number of statement's, which are correct with respect to the compression of carbon dioxide from point (a) in the Andrews isotherm from the following is _________. A. Carbon dioxide remains as a gas upto point (b) B. Liquid carbon dioxide appears at point (c) C. Liquid and gaseous carbon dioxide coexist between points (b) and (c) D. As the volume decreases from (b) to (c), the amount of liquid decreases

Correct answer

0

Step-by-step solution

Andrews noticed that at high temperatures isotherms look like that of an ideal gas and the gas cannot be liquefied even at very high pressure. As the temperature is lowered, shape of the curve changes and data shows considerable deviation from ideal behaviour. Carbon dioxide remains as a gas only up to point b . At point b , liquid of a particular volume appears. Further compression does not change the pressure. Liquid and gaseous carbon dioxide coexist and further application of pressure results in the condensatio
