Question

Suhu air 20°c dgn massa 1000 gram dipanaskan dgn kalor sebesar 50 kkal. jika diketahui kalor jenir air 1 kkal/kg°C, suhu air setelah dipanaskan menjadi? tolong beserta jawaban ya

Answer 1

T₁ = 20°C
m₁ = 1000 g = 1 kg
Q = 50 kkal
c = 1 kkal/kg°C
T₂ = ?
Q = m * c * ΔT
50 = 1 * 1 * ΔT
ΔT = 50
T₂ - T₁ = 50
T₂ - 20 = 50
T₂ = 70°C
