Physics Question from JEE Main 2026 · 28 January, Shift 1

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