Rationale for change
QID 401166:
Not sure how to state a rationale here, beyond the fact that this equation is necessary to know to solve this problem (I'm in the physics section now, so I hope this is a reasonable way to tag things; if not, please let me know).
It just asks you to calculate the joules, given the other aspects. But the equation you have to know to know how to solve it.

\(Q =\) {{c1::\(mc\Delta T\)}}
Give the equation for heat released or absorbed by a system:
\(Q =\) {{c1::\(mc\Delta T\)}}
Extra
Q = heat energy
m = mass of object (releasing or absorbing Q)
c = specific heat capacity (amount of energy that must be added to the substance to raise the temperature by 1°C or 1K)
∆T = change in temp
NOTE:
Specific Heat Capacity (lower case "c")
c = amount of energy needed to raise one gram of a specific substance by 1°C or 1K.
Units: J/g·°C
Equation: \(Q =\) \(mc\Delta T\)
Heat Capacity (capital "C")
C = amount of heat required to raise the temperature of an entire object (regardless of mass) by 1°C or 1K.
Units: J/°C
Equation: \(Q =\) \(C\Delta T\)
