Problem

An astronaut's heating system fails during a spacewalk, and she needs to warm her gloves using only a small emergency heating element. The heating element can operate in two modes: Mode A: Constant power output of

P = 12\;\text{W}

for

t = 300\;\text{s}

Mode B: Variable power that starts at

P_0 = 24\;\text{W}

and decreases linearly to zero over the same

t = 300\;\text{s}

The glove acts as a perfect thermal reservoir that absorbs all the heat energy. Which mode delivers more total energy to warm the glove, and by how much?
