10 kg of ice at \(-10^\circ\text{C}\) is added to 100 kg of water to lower its temperature from \(25^\circ\text{C}\).
Consider no heat exchange to surroundings.
The decrement in the temperature of water is ________ \( ^\circ\text{C} \).
(Specific heat of ice \(=2100\,\text{J kg}^{-1}\!^\circ\text{C}^{-1}\),
specific heat of water \(=4200\,\text{J kg}^{-1}\!^\circ\text{C}^{-1}\),
latent heat of fusion of ice \(=3.36\times10^5\,\text{J kg}^{-1}\))
