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. at this point, what is the temperature of the water? 67.3°c 150.0°c 124.9°c 25.1°c

Explanation:

Step1: Heat transfer principle

When two substances are in thermal contact, heat flows from the hotter substance to the colder one until thermal equilibrium is reached. Thermal equilibrium means that the two substances (in this case, the metal pellets and the water) have the same temperature.

Step2: Determine the final temperature

The metal pellets cool down to \(67.3^{\circ}C\). At thermal equilibrium, the temperature of the water will be the same as the temperature of the metal pellets.

Answer:

\(67.3^{\circ}C\)
