Sub Topic Name : The Relationship Between CP And CV Of An Ideal Gas |
|
Introduction
• CP- Heat capacity at constant volume • Cv- heat capacity at constant pressure • Cp- Cv = R (gas constant)
Pre-Requisites:
System, heat
Activity:
Fish can survive in summer due to the large heat capacity of water.
Real Life Question:
How do the fish survive in the pond in summers?

What you learn in Theory:
• CP- Heat capacity at constant volume. • Cv- heat capacity at constant pressure. Cp- Cv = R (gas constant)
What you learn in Practice:
It is commonly stated as the law of conservation of energy i.e., energy can neither be created nor be destroyed.
