Volume versus temperature graphs for a given mass of an ideal gas are shown in Fig. at two different values of constant pressure. What can be inferred about relation between `P_(1) and P_(2)`?

Options

A. `P_(1) gt P_(2)`
B. `P_(1) = P_(2)`
C. `P_(1) lt P_(2)`
D. data is insufficient.

Answer

A

Explanation

When pressure of an ideal gas is constant, Chale's law is obeyed, i.e. `V prop T or V/T = constant = 1/P` From the slopes of curves.
