Significance / Importance of Boyle’s Law

According to Boyle’s law, at constant temperature the density of gas is directly proportional to pressure. This is because density depends on volume, smaller the volume higher the density. So when pressure is applied, volume is reduced i.e. density is increased.
Thus, at higher altitudes, as the atmospheric pressure is low, the air is less dense. As a result less oxygen is available for breathing. That is why mountaineers have to carry oxygen cylinders with them.

  2. Density is directly proportional to pressure and desnity depends upon volume then it's not Boyle's law cause for Boyle's law the volume is inversely proprotional to pressure.

      Its boyle's law
      Mind it

    2. For boyles law temperature must be constant. Temperature isn't constant in mountain so it can't be applied.

    3. Boyle's law states the inverse relationship between pressure and volume of a gas when the temperature is held constant. At an extremely low temperature gases become liquid. Boyle's law does not apply to liquid so as long as the state of matter is gaseous Boyle's law holds true.
