How much heat is required to increase the temperature of 100.0 grams of iron from 15.0oc to 40.2oc? (the specific heat of iron is 0.46 j/g xoc) 2520 j 46 j 1160 j 1850 j 690 j

Answer : The heat required is 1160 J.

Explanation :

Formula used :

or,

where,

Q = heat required = ?

m = mass of iron = 100.0 g

c = specific heat of iron =

= initial temperature  =

= final temperature  =

Now put all the given value in the above formula, we get:

Therefore, the heat required is 1160 J.
