Kajian pustaka tentang kalori meter




Efek tyndall adalah hamburan cahaya oleh partikel-partikel suspensi. Larutan sesungguhnya bersifat homogen dan jernih. Jika larutan itu dikenai sinar, maka akan tembus cahaya.
Lain halnya dengan suspensi (campuran heterogen dan keruh), jika dikenai sinar, maka sinar akan dihamburkan oleh parikel-partikel suspensi itu. Seolah-olah sinar diserap sehingga dibelakang suspense tampak gelap. Hamburan cahaya oleh partikel suspense ini diselidiki oleh Tyndall, karenanya disebut dengan efek Tyndall. 

Alat dan Bahan :

            Alat : - Senter
                      -Gelas ukur

·         Kemudian tuangkan 80 ml air lalu aduk hingga campuran tercampur rata.
·         Lalu sinarilah larutan gula dengan senter dan lihatlahlah ada tidaknya efek tyndal pada larutan gula kemudian cuci gelas ukur hingga bersih
·         Percobaan 2 , tuangkan garam secukupnya ke dalam gelas ukur.
·         Kemudian tuangkan 80 ml air lalu aduk hingga campuran tercampur rata.
·         Lalu sinarilah larutan garam dengan senter dan lihatlahlah ada tidaknya efek tyndal pada campuran kemudian cuci gelas ukur hingga bersih.

  22. Today, I went to the beach front with my kids. I found a sea shell and
    gave it to my 4 year old daughter and said "You can hear the ocean if you put this to your ear."
    She put the shell to her ear and screamed. There was a hermit crab inside
    and it pinched her ear. She never wants to go back!
    LoL I know this is completely off topic but I had to tell someone!
