What conclusion would you draw from the following graphs for an ideal gas?

Options

A. As the temperature is reduced, the volume as well as the pressure increases
B. As the temperature is reduced, the volume becomes zero and the pressure reaches infinity
C. As the temperature is reduced, the pressure decreases
D. A point is reached where, theoretically, the volume becomes zero

Answer

C, D

Explanation

`{:("at constant volume " ,"at constant P"),(P prop T,V prop T),(P = KT,V= KT),(P = K (t^(@)C + 273.15),V= K (t^(@)C + 273.15)):}`
