15 Introduction SC/BC Objective Indicator Content Problem Quit Pemuaian Pengertian Pertambahan panjang, luas, dan volume benda saat dipanaskan. Penjelasan Saat dipanaskan, molekul benda bergerak lebih cepat dan jarak antar molekul bertambah. Akibatnya benda akan memuai. Sebaliknya jika didinginkan molekul akan bergerak lambat dan jarak molekul berkurang sehingga benda akan menyusut.
