Title: Thermochemistry heating to cooling problem
Post by: prasamb@yahoo.com on December 11, 2022, 01:55:44 PM
As a 10.0 g piece of Aluminum, c=.2157 cal/g C(degree celcius), and a 10.0 g piece of iron, c=0.1074 cal/g C(degree celcius), cools down from
100 C (degree celcius) to 28.9 C(degree celcius) how does the amount of heat transferred from each metal compare?

To compare the amount of heat released we will use this equation with both metals.
q = mc∆t
m and ∆t  is same in both the cases.
So just compare their specific heat capacities.
One with high specific heat capacity means more heat is released.
