The specific heat of nickel is 0.44 J/g°C. How much energy needed to change the temperature of 95.4g of nickel from 32°C to 22°C. Is the energy absorbed or released?
First of all, We will find whether the energy is absorbed or released.
The easiest way to find that is to observe the change in temperature.
We can see that,
So, The Heat Energy is released.
Now, Let's Calculate the Heat.
Now, From the Question,
So, The Heat Energy Released is
The negative sign indicates the energy is released.
Hope this helps.
