  • Teori kinetik gas  menyatakan bahawa molekul-molekul udara sentiasa bergerak  bebas  dan  berlanggar  pada  dinding  bekasnya.
  • Kekerapan perlanggaran antara molekul-molekul udara pada dinding bekasnya akan menghasilkan daya yang menolak pada dinding bekas tersebut 
  • Daya ini dikenali sebagai  tekanan  udara

    • Apabila bekas tertutup dimampatkan
    • isi padu ruang di dalam bekas dikurangkan 

    (Teori Kinetik Gas)
    • Hal ini menyebabkan zarah-zarah udara berlanggar lebih kerap dengan dinding bekas

    • Apabila suhu udara di dalam bekas tertutup bertambah
    • zarah-zarah udara bergerak dengan lebih cepat. 

    (Teori Kinetik Gas)
    • Hal ini menyebabkan zarah-zarah udara melanggar dinding bekas dengan lebih kerap dengan daya yang lebih kuat 
    • Oleh itu, tekanan udara di dalam bekas meningkat.
