A pipe weighing 2 kg and made out of iron is heated until the pipe reaches a temperature of 96 ° C The specific heal capacity of iron is 460J/kg°C. The hot pipe is submersed in cold water ( temperature 9 ° C ) with a volume of 30 litre . The specific heat capacity of water is 4184 J/kg°C . Calculate the final temperature of the pipe and water when equilibrium is reached
