Apakah kimia itu?

Kimia merupakan cabang ilmu pengetahuan yang berhubungan dengan sifat, struktur, dan komposisi bahan dan reaksi mereka antara satu sama yang lain. Kimia adalah studi tentang materi dan interaksi antara berbagai jenis materi. Materi adalah segala sesuatu yang memiliki massa dan menempati ruang. Langkah pertama dalam belajar lebih banyak tentang kimia adalah dengan membaca sebanyak yang Anda bisa pada bidang yang Anda minati.

 

Kimia memiliki empat bidang utama dan banyak sub-spesialisasi. Keempat bidang utama tersebut adalah :

1. Kimia Organik - Studi dari unsur karbon dan senyawanya termasuk materi hidup.
   



2. Kimia anorganik - Penelitian dari semua elemen lain hal non-hidup.
   


3. Kimia analitis - Penelitian dari "Apa itu?" atau kimia kualitatif dan "Berapa banyak yang ada?" yang kimia kuantitatif. kimia analitis adalah analisis senyawa.
   


4. Kimia Fisik - Aspek-aspek kuantitatif dari sifat fisik bahan dan hubungan mereka dengan struktur kimia dan komposisi.
