Webanswer with evidence from the lab. 2. Which substance required the most energy to change its temperature? 3. Which material cooled the fastest once the light was turned off? Support your answer with evidence from the lab. 4. How do these results compare to your hypothesis? 5. Air in the troposphere is heated from the bottom up by heat given off by WebFeb 1, 2024 · Exercise 7.3.3. A coffee-cup calorimeter contains 50.0 mL of distilled water at 22.7°C. Solid ammonium bromide (3.14 g) is added and the solution is stirred, giving a final temperature of 20.3°C. Using the same assumptions as in Example 7.3.3, find Δ Hsoln for NH 4 Br (in kilojoules per mole). Answer: 16.6 kJ/mol.
