A 30.0 g mass of iron at 24.5°C is heated to 45.0°C. The theoretical specific
heat capacity of iron is 0.449 J/g.°C. How much thermal energy was added to
the iron?

Answer:

276.135 J

Explanation:

Given that:

mass of Fe = 30.0 g

initial temperature = 24.5°C

final temperature = 45.0°C

specific heat of Fe = 0.449 J/g°C

We can determine the thermal energy added by using the formula;

Q = mcΔT

Q = 30.0g × 0.449 J/g°C × (45.0 - 24.5)°C

Q = 276.135 J
