Numericals based on Charles's Law:
1. What will be the volume of a gas when 3 litres of it is cooled down from 15° t0 -73° at constant temperature.
2. To what temperature must a gas at 300K be cooled down in order to reduce its volume to 1/3rd of its original volume, pressure remaining constant.
3. Prove that thr volume of a gas at 273°C is twice its volume at 273K, at constant temperature.
