Q5. Correct option is : The final temperature of water in beaker B with the aluminum will be higher than the final water temperature in beaker A with the copper.
Explanation
Specific heat of aluminum metal is higher that specific heat of copper metal. This means aluminum metal absorbs more heat than copper for the same mass and initial temperature.
This more heat absorbed by aluminum, when released upon addition to water, increases the final temperature of water.
