Pure water has a melting point of 0 degrees Celsius (32 degrees Fahrenheit). This means that at or below this temperature, water exists in its solid form, known as ice. On the other hand, a sugar solution has a lower melting point compared to pure water. The presence of dissolved sugar particles disrupts the crystal lattice of water, causing it to melt at a lower temperature. The amount by which the melting point of water is decreased depends on the concentration of the sugar solution. The more concentrated the solution, the lower its melting point.

Boiling Point

The boiling point of pure water is 100 degrees Celsius (212 degrees Fahrenheit) at sea level. This is the temperature at which water changes from a liquid to a vapor or gas. Adding sugar to water increases the boiling point. The dissolved sugar particles interfere with the formation of water vapor bubbles, making it more challenging for the liquid to transform into a gas. The higher the sugar concentration, the higher the boiling point of the solution.

In summary, the melting point of a sugar solution is lower than that of pure water, while the boiling point is higher. These changes are direct consequences of the presence of dissolved sugar particles, which disrupt the intermolecular interactions in water and alter its physical properties. Understanding the melting and boiling points of sugar solutions is crucial in various fields, including food science, chemistry, and engineering, where controlling these properties is essential for specific applications.
