Determine the specific heat capacity of an alloy that requires 59.3 kj to raise the temperature of 150.0 g alloy from 298 k to 398 k. 4.38 j/g°c 1.87 j/g°c 2.53 j/g°c 3.95 j/g°c 2.29 j/g°c

The heat that is required to heat up a substance is calculated through the equation,

     H = McpdT

where H is the heat, m is the mass, cp is the specific heat, and dT is the difference in the temperature. 

To calculate for the cp,

     cp = H/MdT

Substituting the known values,
 
   cp = (59.3 x 10^3 J)/(150 g)(398 K - 298 K)

    cp = 3.953 J/gC

Hence, the answer is the last choice. 

Independent variable is something that is changed in a experiment.
