Suhu akhir yang di peroleh apabila 2 kg air bersuhu 20°c di campur dengan 5 kg air bersuhu 100°c

Q lepas = Q terima m x c x Δt = m x c x Δt Karna sama-sama air, c nya bisa kita coret m x Δt = m x Δt 5 kg x (Tc - 20 c) = 2 kg x (100 - Tc) 5 Tc - 100 = 200 - 2 tc 7 Tc = 300 Tc = 300/7
m x c x Δt = m x c x Δt
Karna sama-sama air, c nya bisa kita coret
m x Δt = m x Δt
5 kg x (Tc - 20 c) = 2 kg x (100 - Tc)
5 Tc - 100 = 200 - 2 tc
7 Tc = 300
Tc = 300/7
