Answer:
B
Explanation:
it's converts electrical energy to mechanical energy.
The amount of heat required is B) 150 J
Explanation:
The amount of heat energy required to increase the temperature of a substance is given by the equation:
![Q=mC\Delta T](https://tex.z-dn.net/?f=Q%3DmC%5CDelta%20T)
where:
m is the mass of the substance
C is the specific heat capacity of the substance
is the change in temperature of the substance
For the sample of copper in this problem, we have:
m = 25 g (mass)
C = 0.39 J/gºC (specific heat capacity of copper)
(change in temperature)
Substituting, we find:
![Q=(25)(0.39)(15)=146 J](https://tex.z-dn.net/?f=Q%3D%2825%29%280.39%29%2815%29%3D146%20J)
So, the closest answer is B) 150 J.
