$50 \mathrm{~g}$ of copper is heated to increase its temperature by $10^{\circ} \mathrm{C}$. If the same…
- $6^{\circ} \mathrm{C}$
- $10^{\circ} \mathrm{C}$
- $5^{\circ} \mathrm{C}$
- $15^{\circ} \mathrm{C}$
Solution

Since, the same amount of heat supplied to copper and water $Q_1=Q_2 \Rightarrow m_1 s_1 \Delta t_1=m_2 s_2 \Delta t_2$ Substituting the value, we get $50 \times 420 \times 10=10 \times 4200 \times \Delta t_2$ $\Delta t_2=5^{\circ} \mathrm{C}$
