Show Solution
Solution and Explanation
The correct expression for enthalpy (H) is:
\(H=U+PV\)
Where:
- H is the enthalpy of the system.
- U is the internal energy of the system.
- P is the pressure of the system.
- V is the volume of the system.
Enthalpy is a thermodynamic property that represents the total heat content of a system at constant pressure. It is often useful in chemical and physical processes, particularly when analyzing heat transfer and chemical reactions occurring at constant pressure.

- Two vessels \( A \) and \( B \) are of the same size and are at the same temperature. Vessel \( A \) contains \( 1 \, \text{g} \) of hydrogen and vessel \( B \) contains \( 1 \, \text{g} \) of oxygen. \( P_A \) and \( P_B \) are the pressures of the gases in \( A \) and \( B \) respectively. Then \( \frac{P_A}{P_B} \) is:
