Interpretation:
The molar heat capacity of CH3CH2OH(l) has to be determined.
Concept Introduction:
Enthalpy of reaction can be used to find heat capacity (cP). Heat capacity is the value of energy for particular substance that is required to raise substance’s temperature by 1 °C or 1 K. The expression to calculate heat capacity is as follows:
cP=qPΔT
Here, qP input of energy at constant pressure, ΔT is increase in temperature after input of energy.
The value heat capacity of unit mole substance is known as molar heat capacity and it is represented by CP. The expression of molar heat capacity is as follows:
CP=qPnΔT
Here, n is number of moles.
Also, The value heat capacity per gram is known as specific heat capacity and it is represented by csp. The expression of molar heat capacity is as follows:
csp=qPmΔT
Here, m is mass in grams.
