an iron weighing 50 grams absorbs 256.0 J of heat and warms by 11.4C What is the specific heat of the iron can
Arturiano [62]

The specific heat of the iron can is determined as 0.449 J/g⁰C.

<h3>Specific heat of the iron can</h3>

The specific heat of the iron can is calculated as follows;

Q = mcΔθ

c = Q/mΔθ

where;

  • Q is quantity of heat
  • Δθ is change in temperature
  • m is mass

c = 256/(50 x 11.4)

c = 0.449 J/g⁰C

Thus, the specific heat of the iron can is determined as 0.449 J/g⁰C.
