<u>**Answer:**</u>** The correct answer is Option b.**

<u>**Explanation:**</u>

**To calculate the amount of heat absorbed or released, we use the following equation:**

**.....(1)**

where, q = amount of heat absorbed or released.

m = mass of the substance

c = heat capacity of water = 4.186 J/g ° C

= Change in temperature

**We are given:**

**Putting values in equation 1, we get:**

q = 5023.2 J

**We are given:**

**Putting values in equation 1, we get:**

q = 1674.4 J

Heat gained by Trial 1 than trial 2 =

Hence,** the amount of heat gained in Trial 1 about 3347 J more than the heat released in Trial 2.**

**Thus, the correct answer is Option b.**
