The Specific Heat Capacity of Iron

What is the specific heat capacity of iron?

The specific heat capacity of iron is 450.5 J/g°C.

What will be the final temperature of a 15.5 kg block of iron if it is heated with 250 J?

Choose the correct answer:

a) 20.03°C

Answer:

The final temperature of the iron will be 20.03°C.

Iron has a specific heat capacity of 450.5 J/g°C, which means it requires 450.5 Joules of energy to raise the temperature of 1 gram of iron by 1 degree Celsius.

In the given scenario, a 15.5 kg block of iron with an initial temperature of 20 degrees Celsius is heated with 250 J of energy. By using the formula for heat required, we can calculate the final temperature of the iron to be 20.03°C.

This calculation involves the mass of the iron block, the initial and final temperatures, as well as the heat added to the system. By plugging these values into the formula, we can determine the final temperature accurately.
