Question

A sample of iron receives 50 J of heat energy that raises the temperature of the iron to a delta T of 25.0°C. If iron has a specific heat of 0.10 J/g°C, what is the mass of the iron sample?

Answer 1

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
