10. If heat is added to an isobaric process then the The internal energy will increase and external energy decrease The internal energy will decrease and external energy will increase Both the internal energy and external energy will decrease Both the internal energy and external energy will increase Only the internal energy will change 11. The specific heat of lead and water are \( c_{l}=130 \mathrm{~J} / \mathrm{kg} \cdot C^{\circ} \) and \( c_{w}=4186 \mathrm{~J} / \mathrm{kg} \cdot C^{\circ} \) respectively which statement is true? Water is a better conductor of heat Lead is better insulator of heat Water is a better insulator of heat Lead and water are equally good insulators of heat. Lead and water are equally good conductors of heat. 12. If the latent heat of water is \( L_{f}=333 \mathrm{~kJ} / \mathrm{kg} \) and \( 111 \mathrm{~kJ} \) of heat is applied to a block of ice at \( T=0^{\circ} \mathrm{C} \), then about what percentage of the ice will melt? \( \begin{array}{r}10 \% \\ \hline 20 \% \\ \hline 30 \% \\ \hline 40 \% \\ \hline 60 \%\end{array} \)
