Question

hot metal pellets at 150.0 °c are added to water. that is at 25.1 °c. the pellets cool to 67.3 °c. what is the temperature change in the metal pellets? (hint: temp final - temp initial) -82.7 °c -67.3 °c 25.1 °c 82.7 °c

Explanation:

Step1: Identify initial and final temperatures

Initial temperature of metal pellets \( T_{i}=150.0^{\circ}C \), final temperature \( T_{f} = 67.3^{\circ}C \)

Step2: Calculate temperature change

Using the formula \( \Delta T=T_{f}-T_{i} \), we substitute the values: \( \Delta T=67.3 - 150.0\)
