Question

The specific heat of a copper metal is 0.385J/g-°K. How many kJ of heat are needed to raise the temperatue of 1.1 kg block of copper from 27.5°C to 50°C?

-Thank you ☺

Answer 1

M=1.1kg,C=0.385,change in temp=50-27.5=22.5C.Q=1.1x0.385x22.5=?KJ

Answer 2

q = mass Cu x specific heat Cu x (Tfinal-Tinitial)
The answer will be in J (if you use 0.385 J/g*K) so convert the answer to kJ.
