TINDAK BALAS EKSOTERMIK & ENDOTERMIK









Video di bawah adalah gelagat pelajar kesayangku menguji teori di atas dengan mengkaji tindak balas...

a) Natrium hidroksida  dan air : tindak balas eksotermik
b) Natrium tiosulfat dan air : tindak balas endotermik


keputusannya....
a) tindak balas natrium hidroksida dengan air :
    = tindak balas eksotermik
    = tabung uji terasa panas
    = suhu awal 30C 
    = suhu akhir 38C
    = Perubahan suhu : +8C
   = suhu meningkat

b) tindak balas natrium tiosulfat dengan air :
    = tindak balas endotermik
    = tabung uji terasa sejuk
    = suhu awal 30C 
    = suhu akhir 24C
    = Perubahan suhu : - 6C
   = suhu menurun

    Kenapa kalau masak telur tu endo yer... Sbb asal telur mentah kan ikatan zarah tu jauh...klu tenaga diserap bkn ker ikatan semakin jauh... Sdgkan telur bila mask jd pepejal
