For a fixed mass of gass at constant temperature, if we decrease volume, the pressure will _________?
مستقل درجہ حرارت پر گیس کے ایک مقررہ ماس کے لیے، اگر ہم حجم کو کم کرتے ہیں، تو دباؤ کیا ہوگا؟
Answer: Increase
Explanation
According to Boyle's Law, for a fixed mass of gas at constant temperature, the pressure of the gas is inversely proportional to its volume
. This means that if you decrease the volume, the pressure will increase, and vice versa.
Mathematically, it is expressed as: P1V1 =P 2 V2 where P is the pressure, and V is the volume.
Therefore, if the volume decreases, the pressure will increase.
