Q: Does distance exist in thermodynamic coordinates?

anantaConsider a $P$-$V$ space. The question is a simple one: can we measure distance between two states $(P_1,V_1)$ and $(P_2,V_2)$? Using simple Euclidian distance $d^2 = (P_2-P_1)^2 + (V_2-V_1^2)$ does not seem to work because the units of pressure are different than those of volume and these, or t...

Q: Calculation of formation heat given molar heat capacities and reaction enthalpy

Harikrishnan M Consider the following reaction for the formation of liquid water at $\pu{298 K}:$ $$\ce{H2(g) + 1/2 O2(g) -> H2O (l)} \quad \Delta_\mathrm rH = \pu{-286 kJ/mol}$$ If molar heat capacities (at constant pressure) of $\ce{H2(g)},$ $\ce{O2(g)},$ $\ce{H2O(g)}$ are given as $39,$ $29$ and $\pu{75 J K...
