When 17.0 grams of an unknown metal is cooled from 35.0°c to 10.0°c it releases 862 joules of energy. what is the specific heat capacity of the unknown metal?

The specific  heat  capacity  of  unknown  metal  is  calculated  using the  following  formula

Q=MC  delta  T  where
Q= heat(862 j)
M=  mass  (17 g)
C=  specific  heat capacity=?
delta T = change in  temperature  (  35-10= 25 c)

by making  C the  subject  of the  formula  C=Q/m  delta T

=  862 j/( 17 g  x25 c) = 2.028 j/g/c
