How much heat is required to heat a 500-gram piece of copper from 20 degrees to 225 degrees Celsius?

How much heat is required to heat a 500-gram piece of copper from 20 degrees to 225 degrees Celsius? The specific heat capacity of copper is 400 joules per kilogram.

Let’s translate the mass of copper, which is presented in the condition of our problem, in kilograms:

1000 grams – this will be the same as 1 kilogram;

500: 1000 = 0.5.

As you know, the amount of heat required for heating can be calculated using the following formula:

Q = m * c * (t2 – t1), where m is the mass of the substance, c is its specific heat capacity, and t2 and t1 are the final and initial temperatures, respectively.

Now let’s calculate:

0.5 * 400 * (225 – 20) = 200 * 205 = 41000.

Answer: 41,000 J.
