15.1 Example 1

A block of copper (specific heat 390 J/kg*K) of 0.5 kg have an initial temperature of 17 C. If this block get 150 calories, what will be its final temperature in Celsius?

Solution with FisicaLab

Select the Thermodynamics group and, inside this, the Calorimetry and gases module. Erase the content of the chalkboard. And add one element Block and one element Applied heat. As show the image below:

To the element Block, that represent the block of copper, we have:

Name

0

m

0.5

c

390

Ti

17 @ C

Tf

tf @ C

And to the element Applied heat:

Q

150 @ cal

Now click in the icon Solve to get the answer:

tf = 20.221 C ;
Status = success.
