Explain the following observations: a. More sugar dissolves in hot tea than in iced tea.

Verified step by step guidance

1. Identify the solubility principle: Solubility of solids in liquids generally increases with temperature.
2. Consider the kinetic energy: At higher temperatures, molecules move faster, increasing the interaction between sugar and water molecules.
3. Understand the dissolution process: The increased movement at higher temperatures helps break the intermolecular forces in sugar, allowing more sugar to dissolve.
4. Relate to the specific scenario: In hot tea, the higher temperature provides more energy for sugar molecules to disperse among water molecules compared to iced tea.
5. Conclude with the observation: Therefore, more sugar can dissolve in hot tea than in iced tea due to the increased solubility at higher temperatures.

Key Concepts

Solubility

Solubility refers to the ability of a substance (solute) to dissolve in a solvent, forming a solution. It is influenced by factors such as temperature, pressure, and the nature of the solute and solvent. Generally, higher temperatures increase the solubility of solids in liquids, allowing more sugar to dissolve in hot tea compared to iced tea.

Temperature Effects on Solubility

Temperature plays a crucial role in the solubility of solids in liquids. As temperature increases, the kinetic energy of the molecules also increases, leading to more frequent and energetic collisions between solute and solvent molecules. This results in a greater number of solute particles being able to break away and enter the solution, which explains why more sugar dissolves in hot tea.

Saturation Point

The saturation point is the maximum concentration of solute that can dissolve in a solvent at a given temperature. When a solution reaches this point, no more solute can dissolve, and any additional solute will remain undissolved. In the case of tea, hot tea can reach a higher saturation point for sugar than iced tea, allowing for more sugar to dissolve before saturation occurs.
