Solve for the indicated letter. 1. Solve for c: Q= mcΔt 2. Solve for c: E = mc2 3. Solve for tf : Q= mc(tf ‐ti) Sep 14­8:35 AM 1 Sep 14­7:47 AM 2 Sep 14­7:46 AM 3 Sep 14­7:48 AM 4 Sep 14­7:48 AM 5 Sep 14­7:49 AM 6 FYI • Keep in mind that heat & specific heat are not the same thing. • Heat and energy are the same thing. • Cannot mix J and kJ in the same problem • Cannot mix g and kg in the same problem • To solve for final or initial temperature, substitute (Tf ­ Ti) for ΔT then rearrange equation to solve for desired variable. • Textbook problems will expect you to be able to apply previously taught material • You may need to refer to specific heat table on page 60 Sep 14­7:52 AM 7
