Problema Solution
what is the specific heat ( in cal / g x c) of an unknown metal that requires 33.4cal to heat from 24.0c to 100.0c ? The mass of the metal is 50.19g
Answer provided by our tutors
change of temperature: 100 - 24 = 76
let 'X' represent the specific heat, we want to calculate the amount of heat per gram required to raise the temperature by one degree Celsius:
33.4 cal = 50.19grams X calories/grams*Celcius * (76 Celcius)
33.4 = 50.19 * X * 76
solving for 'X' we have X=0.008756
the specific heat of the unknown metal is approximately 8.76e-3 cal/g x c
