Q. Explain Combined Gas Law?
Ans.
The combined gas law combines Boyle's law and Charles' law.
The combined gas law describes situations where a gas undergoes simultaneous changes in pressure, temperature, and volume.
Mathematically, the combined gas law can be expressed as:
- PV / T = k (where k is a constant) or
- P1V1/T1 = P2V2/T2 (the 1 and 2 subscripts refer to initial and final conditions, respectively)
Note: In the second expression of the combined gas law, there are six variable quantities. We can determine any one of them if we know the other five.
