QuestionFind the temperature change of a $25.0 \mathrm{~g}$ brass piece from $325^{\circ} \mathrm{C}$ to $42.0^{\circ} \mathrm{C}$ . $\Delta \mathrm{T}_{\text {brass }}=[?]^{\circ} \mathrm{C}$

Studdy Solution

STEP 1

Assumptions1. The initial temperature of the brass is $325^{\circ} \mathrm{C}$ . The final temperature of the brass is $42.0^{\circ} \mathrm{C}$

STEP 2

The change in temperature is calculated by subtracting the final temperature from the initial temperature.
$\Delta_{\text {brass }} =_{\text {initial}} -_{\text {final}}$

STEP 3

Now, plug in the given values for the initial and final temperatures to calculate the change in temperature.
$\Delta_{\text {brass }} =325^{\circ} \mathrm{C} -42.0^{\circ} \mathrm{C}$

STEP 4

Calculate the change in temperature.
$\Delta_{\text {brass }} =325^{\circ} \mathrm{C} -42.0^{\circ} \mathrm{C} =283^{\circ} \mathrm{C}$ The change in temperature of the brass is $-283^{\circ} \mathrm{C}$ . The negative sign indicates that the temperature has decreased.
