Why does sugar retain heat in liquids?

Sugar retains heat in liquids primarily due to its ability to dissolve and form hydrogen bonds with water molecules. When sugar dissolves, it disrupts the structure of water, creating a more complex solution that can absorb and hold heat more effectively. Additionally, the presence of sugar increases the solution's specific heat capacity, meaning it can store more thermal energy without a significant rise in temperature. This property makes sugary liquids feel warmer and helps maintain heat for longer periods.
