The specific heat of nickel is 0.44 j/g*⁰c. how much energy needed to change the temperature of 95.4g of nickel from 22⁰c to 32⁰c. is the energy absorbed or released?

Answer : The amount of energy needed is, 419.76 J and the energy is absorbed.

Solution :

Formula used :

where,

Q = heat gained or absorbed = ?

m = mass of nickel = 95.4 g

c = specific heat of nickel =      

= final temperature =

= initial temperature =

Now put all the given values in the above formula, we get

The value of Q is positive that means energy is absorbed.

Therefore, the amount of energy needed is, 419.76 J and the energy is absorbed.
