Ravi will win the game because he took hot boiling milk and it heat the speed of dissolving sugar

Introduction:
In this game, Sheela, Saima, and Ravi are trying to dissolve the maximum amount of sugar in the same amount of milk. Each of them has chosen a different temperature for the milk - hot boiling milk, ice-cold milk, and milk at room temperature. Let's analyze the effects of temperature on dissolving sugar and determine who would win the game.

Effects of Temperature on Dissolving Sugar:
The temperature of the milk plays a crucial role in dissolving sugar. Here's how different temperatures affect the process:

1. Hot Boiling Milk:
When milk is hot boiling, the water molecules in the milk move faster and have more kinetic energy. This increased kinetic energy allows the sugar molecules to move more freely and come into contact with the water molecules, resulting in faster dissolving. Therefore, Ravi has an advantage in terms of speed of dissolving the sugar.

2. Ice-Cold Milk:
In ice-cold milk, the water molecules have less kinetic energy, and they move slower. This slower movement makes it difficult for the sugar molecules to come into contact with the water molecules, hindering the dissolving process. As a result, Saima may face challenges in dissolving the sugar effectively.

3. Milk at Room Temperature:
Milk at room temperature provides a balance between hot boiling milk and ice-cold milk. The water molecules have moderate kinetic energy, allowing the sugar molecules to dissolve at a reasonable rate. Sheela's choice of milk at room temperature provides her with a favorable condition for dissolving sugar.

Conclusion:
Considering the effects of temperature on dissolving sugar, it can be inferred that Sheela, who chose milk at room temperature, would have the highest chance of winning the game. Although Ravi's hot boiling milk would dissolve the sugar quickly, the quantity of sugar dissolved is not mentioned in the question. Therefore, Sheela's choice of milk at room temperature strikes a balance between speed and effectiveness of sugar dissolution. Saima's choice of ice-cold milk would likely result in slower and less effective dissolving compared to the other two options.
