Question
An insulated calorimeter contains 100 g of water at 10 °C. A salt is added to the solution, causing the temperature to drop by 3 °C. If twice as much salt were added the solution, assuming it all dissolved, what would be the final temperature of the solution? Group of answer choices7 °C4 °C0 °C10 °C
Solution
The problem states that when a certain amount of salt is added to the water, the temperature drops by 3°C. Therefore, if twice as much salt is added, it can be inferred that the temperature would drop by twice as much, or 6°C.
The initial temperature of the water is 10°C. If the temperature drops by 6°C, the final temperature of the solution would be 10°C - 6°C = 4°C.
So, the final temperature of the solution would be 4°C.
