Homework Statement
Calculate the changes in the entropy of the universe for
a) A copper block of mass 0.5kg is dropped into a lake of 10 degrees with the block having a thermal capicity of 2J/K and a temperature of 100 degrees
Homework Equations
dS=dQ/T
The Attempt at a Solution
ok so I know how to do the question but i am confused on 1 thing;
do i integrate dS=mcdT/T so dQ=mcdT or do i use just dQ=C(t) because it gives me the thermal capacity not the specific heat.
