The enthalpy of a substance (denoted by H), is defined as
A. H = U - PV
B. H = U + PV
C. H =-U + PV
D. H =-U - PV
Answer:B
The enthalpy of a substance (denoted by H), is defined as
A. H = U - PV B. H = U + PV C. H =-U + PV D. H =-U - PV
Explanation: The sum of internal energy (U) and the product of pressure and volume is enthalpy, represented by equation-
