Vedclass · Answer

(B) The heat energy $Q$ required to raise the temperature of a mass $m$ of water by $\Delta T$ is given by the formula $Q = mc\Delta T$.Here,the specific heat capacity of water $c = 4200\, J/(kg \cdot ^{\circ}C)$ or $4.2\, J/(g \cdot ^{\circ}C)$.For option $(B)$: $m = 100\, g = 0.1\, kg$ and $\Delta T = 10^{\circ}C$.$Q = 0.1\, kg 	imes 4200\, J/(kg \cdot ^{\circ}C) 	imes 10^{\circ}C = 4200\, J$.Thus,$4200\, J$ of energy is required to increase the temperature of $100\, g$ of water by $10^{\circ}C$.
