Q
Q: What is the primary purpose of using enthalpy in thermodynamics?
Solution: Enthalpy is defined as the total heat content of a system at constant pressure, making it essential for calculating heat transfer in chemical reactions.
Steps: 4
Step 1: Understand that enthalpy is a measure of heat content in a system.
Step 2: Recognize that enthalpy is used when the pressure in the system remains constant.
Step 3: Learn that enthalpy helps us calculate how much heat is absorbed or released during chemical reactions.
Step 4: Remember that knowing the heat transfer is important for understanding how reactions occur and how energy is used.
