For a fixed mass of an ideal gas the correct representation is

Options

A.
B.
C.
D.

Answer

A, B

Explanation

For fixed mass (m) of an ideal gas:
(a) `:. p alpha (1)/(V)` (at constant m, T)
and `p alpha T` [at constant m,volume (V)]
Thus, (a) is the correct graph.
(b) `:. V alpha T` (at constant m, p) and `p alpha T` (at constant m.p)
`:.` (b) is the correct graph.
(c) `:. p alpha T` (at constant m,p) and `V alpha T` (at constant m,p).
`:.` (c) is incorrect.
(d) `:. p alpha (1)/(V)` (at constant m, T)
and V can never parallel to p for any pressure.
`:.` (d) is incorrect.
