Answer: 20 g

Explanation: heat received Q = m c dT

Q= 50J , dT= 25 C anc c= 0.10 J / g C

And m = Q / c dT

The mass of the iron sample that received the heat is determined as 20 g.

Mass of the iron sample

The mass of the iron sample is calculated as follows;

Q = mcΔT

where;

  • m is mass of the iron sample
  • C is the specific heat capacity
  • ΔT is change in temperature

m = Q/cΔT

m = (50) / (0.1 x 25)

m = 20 g

Thus, the mass of the iron sample that received the heat is determined as 20 g.
