Pengertian Suhu dan kalor

Suhu. Konsep suhu atau temperatur sebenarnya berawal dari rasa panas dan dingin yang dialami oleh indera peraba kita. Berdasarkan apa yang dirasakan oleh indera peraba, kita mengatakan suatu benda lebih panas dari benda yang lain atau suatu benda lebih dingin dari benda lain. Benda yang panas memiliki suhu yang lebih tinggi sedangkan benda yang dingin memiliki suhu yang lebih rendah. Semakin dingin suatu benda, semakin rendah suhunya. Sebaliknya, semakin panas suatu benda, semakin tinggi suhunya. Ukuran panas atau dinginnya suatu benda ini disebut suhu (temperature). Dalam pokok bahasan teori kinetik gas yang akan dipelajari nanti di kelas XI, anda akan memahami lebih mendalam pengertian suhu; apa yang terjadi pada molekul-molekul penyusun suatu benda sehingga tersebut benda bisa terasa panas, hangat, sejuk atau dingin.
