Question

How much heat energy is required to raise the temperature of 0.368 kg of copper from 23.8 degrees * C to 60.0C? The specific heat of copper is 0.0920 cal/(g .^ C) .

Answer 1

1225.58 joule

Step-by-step explanation:

Given mass= 0.368 kg

Initial temperature (T1)= 23.8 degree

Final temperature (T2)= 60.00 degree

Change in temperature(ΔT) T2-T1 = 60.00-23.8 = 36.2 degree celsius

S.H.C of copper= 0.0920 cal/gm

= 0.0920 x 1000=92 j/kg degree celsius

now

heat required=MSΔT

0.368 X 92 X 36.2 = 1225.58 JOULE
