Kita sering menggunakan termometer untuk mengukur suhu badan maupun suhu ruangan,
tapi tahukah kalian bagaimana cara kerja dari termometer itu? Ada berapa jenis satuan
suhu?
Untuk lebih memahami materi tersebut bacalah buku teks pelajaran (BTP): IPA FISIKA
untuk SMP/ MTs Kelas VII . Jakarta: Erlangga hal. 139 s.d. 150. Kemudian kerjakan
aktivitas di bawah ini!
1. Perhatikan gambar di bawah ini!
