A piece of copper of mass 30g loses 60J of heat energy. If the specific heat capacity of copper is 400Jkg−¹K−¹, Calculate the change in the temperature of the copper
![A solid of mass 0.5kg initially at 50oC melts at 60oC. Calculate the quantity of heat required to melt it completely. [specific heat capacity of the solid =2.0KJ kg-1K-1][Specific latent heat of fusion of solid =1.0 KJ kg-1]](https://erudites.ng/wp-content/plugins/contextual-related-posts/default.png "A solid of mass 0.5kg initially at 50oC melts at 60oC.
