good day learners this is easy engineering this time we're going to talk about boyle's law in gas its physical behavior is described by these four variables namely pressure volume temperature and amount or mole in this video we will have boyle's law which is concerned in the relationship of pressure and volume boyle's law was formulated by the famous scientist robert boyle in 1662 this law relates the expansion and compression of the gas at constant temperature in his experiment he has shaped tube with shorter end closed and the long end open he put mercury in the tube and determined the volume of trapped gas when he poured some more mercury he found out that the volume of chopped gas decreases while the change in height of the mercury increases which indicates the pressure also increasing having all the data he then find out that volume and pressure follows this graph as shown when we write it in mathematical terms we have volume is inversely proportional to pressure this relation can be also expressed as the product of pressure and volume is equal to some constant if we have gas under two different conditions we can write the formula as p1 b1 equals b2 v2 in the formula we can see that under certain condition of the gas increasing the pressure would result to decreasing the volume or increasing the volume would result to decreasing the pressure for example the initial volume is 5 liters at pressure 180m what is the volume if we increase the pressure to 280m we first identify the given so we have now we are going to find the final volume we substitute the non-values the formula now solving for the final volume we have therefore the final volume is 2.5 liters we noticed here that the final pressure is doubled so we expect for our volume to be half that's it that is all for now hope you learned something today once again this is easy engineering you
