Mr. Arora introduced Topic 1 with dramatic flair: thermochemistry. He dropped an ice cube into a hot beaker, measured temperature changes, and wrote the first law of thermodynamics on the board. But instead of asking for definitions, he assigned a term project: design a simple experiment that demonstrates energy change, explain it using class concepts, and connect it to a real-world application.

In the lab, the experiment began. They measured the initial temperature of water, added ammonium nitrate into one cup and calcium chloride into another, and recorded rapid temperature drops and rises. The data surprised them: ammonium nitrate’s dissolution decreased temperature, pulling energy from the water, while calcium chloride released heat. Sameer grinned—his gadget worked. Meera’s diagrams showed energy arrows flowing in and out of molecular lattices. Riya connected the observations to enthalpy of solution, breaking ionic lattices, and hydration energy. xam idea class 11 chemistry pdf free download term 1
