Question

A 8.51-g piece of iron absorbs 27.33joules of heat energy, and its temperature changes from 25.99°C to 32°C. Calculate the specific heat capacity of iron.

Answer 1

Answer:

change in temperature = (100 - 25) = 75.0°C.

change in thermal energy = mass × specific heat capacity × change in temperature.

= 0.200 × 4,180 × 75.0.

= 62,700 J (62.7kJ)
