Tasha drops a metal cube into a beaker of water. After heat transfers what is the final temperature of the water?
The final temp. is 25 °C because there is more water than metal
final temp. is btwn 25°C and 50°C bc energy transfers: from metal to water
final temp. is 50 °C bc the metal warms the water to the temp of the metal.
