When a piece of Samarium is taken out of the oven and cools from 230° to 152°, What isthe change in temperature?

Respuesta :

We are asked to determine the change in temperature. To do that we will use the following formula:

[tex]\Delta T=T_f-T_0[/tex]

Where:

[tex]\begin{gathered} \Delta T=\text{ change in temperature} \\ T_f,T_0=\text{ final and initial temperature} \end{gathered}[/tex]

Now, we substitute the values:

[tex]\Delta T=152-230[/tex]

Solving the operations:

[tex]\Delta T=-78[/tex]

Therefore, the change in temperature is -78°
