A steel ball, of mass 10 g and specific heat `100 "cal"//kg(@)C`, is pushed out after being heated inside a furnace. It is quickly caught inside a thick copper vessel of mass 200 g and relative specific heat 0.09 at `50^(@)C` and the vessel is dropped into a calorimeter of water equivalent 20 g containing 180 g of water at`20^(@)C`. The thermometer in the calorimeter shows maximum temperature of `26^(@0C`. Calculate the temperature of the furnace and find the calculation whether there was any local boiling in the calorimeter.

Answer

`794^(@)C`
