R) Work done by a gas	iii) State function
S) Molar heat capacity at constant volume	iv) Path function

TestHub · Accepted Answer

Δ U scales with the size of the system and is fixed by the end states alone, so it depends on the quantity and is a state function (P – ii,iii). Heat is a mode of transfer: path function, and its magnitude scales with the amount of material (Q – ii,iv). Work done by a gas is likewise a path function that scales with the quantity of gas (R – ii,iv). Molar heat capacity at constant volume is per mole, so independent of the quantity, and is a thermodynamic state property (S – i,iii).
