Helium gas is filled in two identical bottles A and B. The mass of the gas in the two bottles is 10 gm and 40 gm respectively. If the speed of sound is the same in both bottles, what conclusions will you draw?

Argon gas is filled in two identical bottles X and Y. The mass of the gas in the two bottles is 5 gm and 25gm respectively. If the speed of sound is the same in both bottles, what conclusions will you draw?

Helium gas is filled in two identical bottles A and B. The mass of the gas in the two boules is 15 g and 90 g respectively. If the speed of sound is the same in both bottles, what conclusions will you draw?

Apparatus: Two plastic bottles, measuring cylinder, thermometer, etc Chemicals: Potassium nitrate, sodium hydroxide, water, etc. (Sodium hydroxide being corrosive, handle it carefully in presence of teacher.) Procedure: Take I 00 mL water in each of the two plastic bottles. Plastic being insulator of heat, the dissipation of heat can be prevented. Note the temperature of water in the bottles. Put 5 g potassium nitrate (KNO_3) in the bottle and shake well. Note the temperature of the solution formed. Put 5 g sodium hydroxide (NaOH) in the other bottle. Shake the bottle well. Note the temperature. In the first bottle, the process of dissolution of potassium nitrate took place while in the second bottle, the process of dissolution of sodium hydroxide took place As per your observation which one is exothermic process and which is an endothermic process?

Two balloons are filled one with pure He gas and the other with air respectively. If the pressure and temperature of these balloons are same, then the number of molecules per unit volume is

Practice problems : A 1 L bottle half-filled with a hydrogen gas is heated at constant pressure such that , its temperature changes by 20 ⁰C . What will be the volume of the hudrogen gas in the bottle after heating ?
