- Homework Statement
- so we did an experiment. basically the teacher gave us each a cube of unknown metal

and we had to figure out what it was using the specific heat.

we put the metal in boiling water until it was 212C

and then we put it in room temp water

and we measured how much it heated the water

he also gave us some lead to find the specific heat of so we can troubleshoot if our data is wrong because of the lab process or the calculation

check out the attached files for more precise instructions

so my results are in this google sheets

i set it so anyone with link can view so you guys should have no problem viewing it

https://docs.google.com/spreadsheets/d/1StBNPECq3Ny0tK_N6-0DT4JGgR_bm3tCwsx2dP8RO_0/edit?usp=sharing

i tried making formulas on some of the data so that i didnt have to do the calculations by hand but something is wrong. im getting 50 J/gC (joules per grams degrees celcius) for my unknown metal, which has to be wrong because the specific heat of water is 4.184 J/gC and water is known to have a high specific heat

please help me

im not sure if this is because of my procedure or my calculations

thank you

- Relevant Equations
- final temperature minus initial temperature = change in temperature

specific heat times mass times change in temp. = change in heat

**Relevant Equations:**final temperature minus initial temperature = change in temperature

specific heat times mass times change in temp. = change in heat

the above is my data from my lab

ive tried to do calculations on paper but i get the same results as in the above spreadsheet

but i know that specific heat is way off...
