Một bình nhiệt lượng kế khối lượng m1=m chứa một lượng nước có khối lượng m2=2m , hệ thống đang có nhiệt độ t1=10 độ C. Người ta thả vào bình một cục nước đá khối lượng M nhiệt độ t2=-5 độ C,khi cân bằng cục nước đá chỉ tan một nửa khối lượng của nó. Sau đó rót thêm một lượng nước ở nhiệt độ t3=50 độ C ,có khối lượng bằng tổng khối lượng của nước và nước đá có trong bình. Nhiệt độ cân bằng của hệ sau đó là t4=20 độ C.Bỏ qua sự trao đổi nhiệt với môi trường xung quanh, coi thể tích của bình đủ lớn, biết nhiệt dung riêng của nước và nước đá lần lượt là c1 = 4200J/(kg.độ); c2 = 2100J/(kg.độ), nhiệt nóng chảy của nước đá là λ=34.104J/kg.k.
