Given,
The specific heat capacity (c) of iron skillet is 0.449 J/ g °C.
Mass of iron skillet, m = 37 g
Temperature difference, T = (240-80)°C
=160 °C
Now using formula,
Heat (Q)= c * m * T
= 0.449 J/ g °C * 37 g * 160°C
= 2658 J
hence heat absorbed by 37g iron skillet when temperature rises form 80 to 240 degree Celsius is 2658 Joules.
