What is the relationship between enthalpy change and the heat capacity at constant pressure (Cp)?
ΔH = Cp * ΔT
ΔH = Cv * ΔT
ΔH = Cp / ΔT
ΔH = ΔT / Cp
Questions & Step-by-Step Solutions
What is the relationship between enthalpy change and the heat capacity at constant pressure (Cp)?
Step 1: Understand what enthalpy change (ΔH) means. It is the amount of heat absorbed or released during a process at constant pressure.
Step 2: Know what heat capacity at constant pressure (Cp) is. It is the amount of heat needed to raise the temperature of a substance by one degree Celsius at constant pressure.
Step 3: Recognize that when a substance's temperature changes, it either absorbs or releases heat.
Step 4: Realize that the relationship between enthalpy change and heat capacity at constant pressure can be expressed with the formula ΔH = Cp * ΔT.
Step 5: In this formula, ΔT represents the change in temperature. So, if you know Cp and ΔT, you can calculate ΔH.
