Interpretation:
The amount of heat energy needed to convert 866g of ice at –15°C to steam at
Concept introduction:
The amount of heatthatis required to raise the temperature having specific heat is calculated by the expression given below:
Here,
The change in temperature is the temperature difference between the final and initial temperatures. It is expressed as follows:
The amount of energy needed for phase change from liquid phase to vaporphase is given by the relation as follows:
Here,
The amount of energy needed for phase change from solid phase to liquid phase is given by the relation as follows:
Here,
