10g water at 10°C, 10 g water at 20°C and 10g water at 60°C are mixed in ideal calorimeter then temperature of mixture is :-

Answer:

Solution:

$m_{1} s (T - T_{1}) + m_{2} s (T - T_{2}) + m_{3} s (T - T_{3}) = 0$

$10 \times 1 \times (T - 10) + 10 \times 1 \times (T - 20) + 10 \times 1 \times (T - 60) = 0 3 T - 9 0^{\circ} = 0 T = \frac{90}{3} = 3 0^{\circ} C$
