`A(s) toA(l), DeltaH^(@)=3Kl//g`
If at 200K above changes become reversible then `DeltaS` Will be : `("Molecular weight of A=50 g//mole")`

At STP, the density of a gas (molecular weight 45) in g//L is

The number of nitrogen atoms in 21 g of nitrogen are: (Molecular Weight of Nitrogen =14 g/mole)

The density of a gas at STP is 1.5 g/L. Its molecular weight is

The density of a gas at STP is 1.5 g/L. Its molecular weight is

Given at A(s) to A(l), DeltaH =x A(l) to A(g), DeltaH =y The heat of sublimation of A will be

Three moles of a ideal gas at 200K and 2.0 atm pressure undergo reversible adiabatic compression until the temperature becomes 250 K for the gas C_(v)" is "27.5JK^(-1)mol^(-1) in this temperature range. Calculate q, w, DeltaU,DeltaH and final V and final P.
