Question: A metal block of density 6000kg/m3 and a mass 1.2kg is suspended through a Spring of spring constant 200N/m .The spring block system is dipped in water kept in a vessel. The water has a mass of 260g and block is at height of 40cm above the bottom of the vessel. If the support to the spring is broken, what will be the rise in temperature of water. Specific heat capacity of block is 250J/kg/K amd that of water is 4200J/kg/K. Heat capacity of the vessel and spring is negligible.
