Define Boyle's law? Volume of ethane gas is 2.5dm^3 at 2.10atm pressure when its pressure is reduced to 1.05atm its volume becomes 5.0dm^3. Explain this change using boyle’s law.

Explanation:
Which class
✍️ Boyle's law states that temperature remaining constant, the volume of a fixed mass of a dey gas is inversely proportional to its pressure.
✍️ In other words, the product of Pressure and Volume of a gas at constant temperature is a constant.
✍️ When volume of the ethane gas was 2.5 dm³ at 2.10 atm pressure, its product = (2.5×2.10) dm³ atm = 5.25 dm³ atm
Again, when pressure of the ethane gas was 1.05 dm³ and its volume was 5.0 dm³, its product = (1.05×5.0) dm³ atm = 5.25 dm³ atm
Thus, the Boyle's law gets verified as the product of pressure and volume of the gas is 5.25 dm³ atm in both cases, i.e., is remaining unchanged or constant (provided that the temperature remains constant).
THIS IS WHAT THE BOYLE'S LAW SAYS!
