Question

In two or more complete sentences, explain how to calculate the amount of energy that is transferred when 150 g of cooper cools from 63.0 °C to 21.0 °C. Is the energy absorbed or released? The specific heat of copper is 0.387 J/g*°C.

Answer 1

-2438.1 J. Heat is released.

Step-by-step explanation:

Answer 2

-2,438 J energy is released

Heat energy is released

Step-by-step 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
