A $V$ - $T$ graph (with $T$ in kelvin) of an ideal gas is a straight line that rises to the right and cuts the temperature axis at a positive value $T_{0}$ . As the temperature increases, the pressure of the gas:

Options:

Answer:

Solution:

$V = a (T - T_{0})$ and $P \propto \frac{T}{V} = \frac{T}{a ( T - T _{0} )}$ . This ratio falls toward $\frac{1}{a}$ as $T$ rises, so the pressure decreases. B.
