Boyle's Law

Air is a gas. Gases have various properties which we can observe with our senses, including the gas pressure, temperature, mass, and the volume which contains the gas. Careful, scientific observation has determined that these variables are related to one another, and the values of these properties determine the state of the gas. In the mid 1600's, Robert Boyle studied the relationship between the pressure p and the volume V of a confined gas held at a constant temperature. Boyle observed that the product of the pressure and volume are observed to be nearly constant. The product of pressure and volume is exactly a constant for an ideal gas. P x V = constant This relationship between pressure and volume is called Boyle's Law in his honor. For example, suppose we have a theoretical gas confined in a jar with a piston at the top. The initial state of the gas has a volume equal to 4.0 cubic meters and the pressure is 1.0 kilopascal. With the temperature and number of moles held constant, weights are slowly added to the top of the piston to increase the pressure. When the pressure is 1.33 kilopascals the volume decreases to 3.0 cubic meters. The product of pressure and volume remains a constant (4 x 1.0 = 3 x 1.33333 ).
Hukum Boyle

Udara ialah gas. Gas memiliki berbagai sifat yang boleh di perhatikan oleh deria kita, termasuk tekanan gas, suhu, jisim, dan isipadu yang di penuhi gas berkenaan. Kajian sain yang teliti telah mendapati bahawa pemboleh ubah pemboleh ubah ini mempunyai hubungan antara satu sama lain, dan nilai nilai ciri ciri ini menentukan keadaan gas berkenaan. Sekitar pertengahan 1600 , Robert Boyle mengkaji hubungan antara tekanan P dan isipadu V bagi gas dalam bekas tertutup yang di letakan dalam suhu yang tetap. Boyle mendapati bahawa hasil darab tekanan dan isipadunya hampir malar ( satu nilai yang tetap). Hasil darap tekakan dan isipadu adalah satu pemalar bagi gas unggul. P x V = pemalar Hubungan antara tekanan dan isipadu ini di kenali sebaagi Hukum Boyle sempena nama nya. Contohnya jika kita ada gas terkurung dalam satu bekas tertutup dengan satu omboh di atas. Keadaan awal gas tersebut mempunyai isipadu sama dengan 4.0 meter padu dan tekanan nya pula 1.0 kilapascal. Dengan menetapkan tekanan dan bilangan mol, pemberat di tambahkan beransur ansur di atas ombohnya untuk meningkatkan takanannya. Bila tekanannya menjadi 1.33 kilopascal isipadunya berkurang kepada 3.0 meter padu. Hasil darab tekanan dan isipadunya kekal tetap ( 4 x 1.0 = 3 x 1.33333 )
