Figure 6.18 shows the V-T graph for a fixed mass of an ideal gas at pressure p_1 and p_2. Can you infer from the graph whether p_1 is greater than p_2?

1.	Figure 6.18 shows the V-T graph for a fixed mass of an ideal gas at pressure p_1 and p_2. Can you infer from the graph whether p_1 is greater than p_2?
Answer» SOLUTION :We have pV=nRT or, `V=(nR)/P T` this shows that the V-T graph is a STRAIGHT line PASSING through the origin for any fixed PRESSURE p(n=constant for a fixed mass). The slope `(nR)/p` Is greater for a smaller value of p. In fig.6.18, the graph for `p_2` has a higher slope. So, `p_2 lt p_1` Thus `p_1` is greater than `p_2`.
