I believe gamma decay but i may be wrong
The magnetic field or force seems to be associated with the lineup of electrons withim the magnet
The right formula to use for this calculation is the heat capacity formula,
Heat absorbed, Q = MCT, Where
M = Mass of the substance = 71
C = Specific heat capacity for iron = 0.450 J/gc
T = Change in temperature = 29 - 11 = 18
Q = 71 * 0.450 *18 = 575.10
The amount of heat absorbed by the iron skillet is 575 J.
Exothermich cools and endo heats so it heats
Wings to fly. Without flying, birds would be near defenseless.
