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
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.
