Question

A piece of copper alloy with a mass of 55.0g is heated from 30 degrees celsius to 45 degrees celsius . In the process, it absorbs 523 J of heat.
a. What is the specific heat of this copper alloy?
b. How much heat will the same sample lose if it is cooled to 25 degrees celsius from 30 degrees celsius?

Answer 1

a. Q = cp m dT -> cp = Q / m dT
where
Q - heat
m - mass
dT - difference in temperature
cp - specific heat capacity

b. use same equation
Q = cp m dT
with specific heat capacity you calculated in a.
