A 49 gram sample of an unknown metal requires 717 Joules of energy to heat it from 30.5◦C to 101◦C. What is the specific heat of this metal? Answer in units of J/g · ◦ C.

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
