An unknown substance has a specific heat capacity of 2.22 J/g °C. If 89.8 grams areheated with 2,420.0 joules of energy, what will the change in temperature be?

Respuesta :

Answer:

The change in temperature will be 12.14°C.

Explanation:

To calculate the change in temperature it is necessary to use the heat formula and replace the values:

- Specific heat capacity (c): 2.22J/g°C

- Mass (m): 89.9g

- Heat energy (q): 2,420.0 J

[tex]\begin{gathered} q=m\cdot c\cdot\Delta T \\ \Delta T=\frac{q}{m\cdot c} \\ \Delta T=\frac{2,420.0J}{89.9g\cdot2.22J/g\degree C} \\ \Delta T=12.14\degree C \end{gathered}[/tex]

So, the change in temperature will be 12.14°C.
