Oblicz temperature nawty o masie 1kg i temperature początkowa 10*C po dostarczeniu 21KJ energii.

[latex]m = 1 kg T_1 = 10 C Q = 21 kJ = 21000 J c_w = 2100 frac{J}{kg * C } T_2 = ? Q = m * c_w * Delta T Q = m * c_w * (T_2 - T_1 ) 21000 J = 1 kg * 2100 J/kg * C * (T_2 - 10 C ) 21000 J = 2100 J/C *(T_2 - 10 C 21000 J /2100 J/C = T_2 -10 C 10 C = T_2 -10 C 10 C + 10 C = T_2 T_2 = 20 C [/latex]
