Q: What is the relationship between enthalpy and internal energy?
Solution:
The relationship is given by the equation H = U + PV, where H is enthalpy, U is internal energy, P is pressure, and V is volume.
Steps: 5
Show Steps
Step 1: Understand that enthalpy (H) and internal energy (U) are both measures of energy in a system.
Step 2: Know that enthalpy includes internal energy plus the energy related to pressure and volume.
Step 3: Remember the equation that connects them: H = U + PV.
Step 4: In this equation, P stands for pressure and V stands for volume.
Step 5: This means that to find enthalpy, you take the internal energy and add the product of pressure and volume.
