The change in the magnitude of the volume of an ideal gas when a small additional pressure $\Delta $P is applied at a constant temperature, is the same as the change when the temperature is reduced by a small quantity $\Delta $T at constant pressure. The initial temperature and pressure of the gas were 300 K and 2 atm. respectively.
If |$\Delta $T| = C|$\Delta $P| then value of C in (K/atm.) is _________.
