Answer : The specific heat of tin is, 0.213 J/g.K
Explanation :
Formula used :

where,
q = amount of heat lost = -399.4 J
c = specific heat capacity of tin = ?
m = mass of tin = 25.0 g
= final temperature = 
= initial temperature = 
Now put all the given values in the above formula, we get:


Therefore, the specific heat of tin is, 0.213 J/g.K
