I know how to do heat capacity problems but i am unsure of how to do them when two materials are combined together. Here is the question. Any help would be great, thanks.(adsbygoogle = window.adsbygoogle || []).push({});

A 5 kg pieces of low carbon steel at room temperature 25°C is placed into contact with a 300g piece of polyethylene at 180°C . What is the final temperature?

Low carbon steel Cp = 480 j/kg.K

Polyethylene Cp = 1.8 x 10^3 j/kg.K
