A 65-g sample of silicon is at 21°C. If 800 cal of energy is transferred to the silicon, what is its final temperature?
Heat transferred, Q = m*C*T
.....................(1)
here,
m = mass of silicon = 65 gram
C = specific heat of silicon = 0.168 Cal/g°C
= (Tfinal -
Tinitial)
Tinitial = 21 °C
Q = energy transferred = 800 Cal
{from equation 1}
800 = (65)*(0.168)*(Tfinal - 21)
Tfinal = 94.26 °C
