Card 0 of 2
What is the specific heat capacity for a 50-gram sample of metal that increases in temperature by 10 degrees celsius when 2000 joules of energy is added?
What is the specific heat capacity for a 50-gram sample of metal that increases in temperature by 10 degrees celsius when 2000 joules of energy is added?
Use the equation:
We can calculate the specific heat capacity for the unknown metal. Since we know the added heat 
, the mass of the sample 
, and the change in temperature 
, we can solve for 
.

sample of an unknown metal at 
is immersed in water and is allowed to reach equilibrium. If final temperature of the system is 
and 
of energy are released, what is the identity of the metal?
A
Recall that the formula for specific heat is 
. Rearranging the equation for specific heat (c) yields 
Remark: keep in mind that the release of energy and the cooling of the metal will give negative values for both
