Question

Which one of the following schematic graphs best represents the variation of p V (in Joules) versus T (in Kelvin) of one mole of an ideal gas? (The dotted line represents p V = T ), , , ,

MARKS App · Accepted Answer

From gas equation, p V = n R T Here, n = 1 mole So , p V = R T Substituting the value of R in Eq. (i), we get p V = 8 . 3 T Clearly, slope of p V versus T line is 8.3 , which is greater than one. Hence, following graph is correct.
