After completing a lab for my chemistry class I am finding it difficult to find the initial temperature of an iron nail after being heated.
Procedure of the lab went as follows: heat an iron nail, place the heated nail in room temperature water, and record the temperature of the water.
The data collected from the lab: Given 1. Specific heat of water-1cal/gc 2. Specific heat of iron-.113cal/gc
Water 1. Volume-75ml 2. Mass-75g 3. initial temp-23c 4. final temp-27c
Nail 1. Mass-2.51g 2. Initial temp-x 3. Final temp-27c
So as I stated previously I have not been successful in finding the initial temp of the Iron nail based off of the given data.
I had tried using (mcΔt)w=(mcΔt)n being (75)(1)(27-23)=(2.51)(.113)(27-X) in the logic of the temperature of the nail and water reaching equilibrium but by using that formula x comes out to be -1029.338c which is most obviously not the initial temperature of the nail.
