Physics - Heat & Thermo Question with Solution | TestHub

$100\mathrm{g}$ of water is heated from $30^{\circ }\mathrm{C}$ to $50^{\circ }\mathrm{C}$. Ignoring the slight expansion of the water, the change in its internal energy is (specific heat of water is $4148\mathrm{J}/\mathrm{kg}/\mathrm{K}$ ):
