How much heat is absorbed by a 37g iron skillet when its temperature rises from 8oC to 24oC?

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.
