Introduction
• H atoms are formed by breaking H-H bonds in dihydrogen. • The enthalpy change in this process is known as enthalpy of atomization.
Pre-Requisites:
Enthalpy, atomization
Activity:
Energy is required to break any substance e.g. a brick wall.
Real Life Question:
How do we get our energy from food?
