MODUL 1 SUHU DAN KALOR SOAL UJI KOMPETENSI A. Pilihan Ganda 1. B. Esai 1. Diketah ui: T bP = -25 T bQ = x T aP = 125 T aQ = 100 T P = 65 T Q = 60 Ditanya : x? Jawab: Jadi, skala bawah es melebur pada termometer Q adalah 0 2 . Diketah ui: T 0 = 10 o C T 1 = 50 o C T= 40 o C Vo alkohol = 2 L alkohol = 10 -5 / o C Vo gelas = 2 L gelas = 3. 10 - 6 / o C Ditanya : V alkohol tumpah ? Jawab: V alkohol tumpah = Vt alkohol setelah memuai - Vt gelas setelah memuai Vt alkohol = Vo ( 1 + alk T) Vt alkohol = 2 ( 1 + 10 -5 .40) Vt gelas = Vo ( 1 + gelas T) Vt gelas = Vo ( 1 + T aP - T P T P - T bP = T aQ - T Q T Q - T bQ 125 - 65 65 – (- 25) = 100 - 60 60 - x 60 85 = 40 60-x 2 3 3 (60 - x) = 90 . 2 180 – 3x = 180 3x = 180 – 180 x = 0
