How much thermal energy (q) is required to heat 15.2g of a metal (specific heat=0.397J/C) from 21.0C to 40.3C? Show steps please.

Question

anonymous · Answer

dE=m*c*(T2-T1)    
m=mass c=specific heat  T2=end temperature  T1=starting temperature   dE=energy

This formula explains how the amount of energy required to heat up a specific substance from one temperature to another is dependent on that substances specific heat, meaning that not all substances absorb heat from the surroundings as well as others. This metal for instance needs only 0.397 J to be heated to 1 degree abrove its starting temperature, whereas water, for instance needs 4.184 J.
