The correct answer to the given question is option 'A'. Let's understand why.
Explanation:
When an object is heated and then left to cool in air, the rate of cooling depends on several factors such as:
1. Surface area: The greater the surface area, the faster the rate of cooling.
2. Shape: Objects with a larger surface area-to-volume ratio will cool faster.
3. Material: The properties of the material, such as thermal conductivity and specific heat, will affect the rate of cooling.
Now, let's consider the three objects given in the question:
1. Sphere: A sphere has the smallest surface area-to-volume ratio of the three objects. Therefore, it will have the slowest rate of cooling.
2. Cube: A cube has a larger surface area-to-volume ratio than a sphere. Therefore, it will cool faster than a sphere but slower than the circular plate.
3. Circular plate: A circular plate has the largest surface area-to-volume ratio of the three objects. Therefore, it will have the fastest rate of cooling.
Hence, the correct answer is option 'A': Cube will cool faster than sphere but slower than the circular plate.
Conclusion:
In conclusion, the rate of cooling of an object depends on several factors such as surface area, shape and material. In this case, the cube will cool faster than the sphere but slower than the circular plate.
