Answer:
-2,438 J energy is released
Heat energy is released
Explanation:
The formula for energy absorbed or released is Q = mT(Cp)
Get temperature in degrees T = 21 - 63 = -42°C
Mass of the cooling cooper m = 150g
Specific heat of copper Cp = 0.387J/g-°C
Put all the above parameters into the formula for energy absorbed or released
Q = mT(Cp)
= 150 x -42(0.387)
= -2438J same as -2.438 KJ
-2438J energy is released
