Heat Capacity and Temperature change
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.
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

hey mate, just letting you know that your values with regard to each material have not come up correctly, there are just squares next to the numbers.
