Answer (2)
This response classifies five mixtures based on visibility, uniformity, and state of matter. Each mixture is analyzed, resulting in a completed table summarizing their properties. Understanding these mixtures helps in practical applications like cooking and environmental science.
;
Sugar and water: Not Visible, Uniform, Liquid.
Oil and water: Visible, NonUniform, Liquid.
Vinegar and water: Not Visible, Uniform, Liquid.
Salt and pepper: Visible, NonUniform, Solid.
Leaf and water: Visible, NonUniform, Liquid.
The completed table is the final answer.
Explanation
Problem Analysis We need to classify each of the given mixtures based on whether the components are visible or not, whether the mixture is uniform or non-uniform, and the state of matter of the mixture.
Sugar and Water
Sugar and water: When sugar dissolves in water, it is no longer visible. The mixture becomes uniform throughout. The state of matter is liquid.
Oil and Water
Oil and water: Oil and water do not mix, and the oil remains visible as a separate layer. The mixture is non-uniform. The state of matter is liquid.
Vinegar and Water
Vinegar and water: Vinegar and water mix completely, and the vinegar is not visible as a separate component. The mixture is uniform. The state of matter is liquid.
Salt and Pepper
Salt and pepper: Salt and pepper do not dissolve in each other and remain visible as separate components. The mixture is non-uniform. The state of matter is solid.
Leaf and Water
Leaf and water: The leaf remains visible in the water. The mixture is non-uniform. The state of matter is liquid.
Final Classification Based on the analysis, here's the completed table:

Examples
Understanding mixtures and their properties is crucial in everyday life. For example, when you're cooking, you need to know if ingredients will dissolve evenly (like sugar in water) or remain separate (like oil and vinegar in salad dressing). This knowledge helps you predict the texture and appearance of your final dish. Similarly, in environmental science, understanding how different substances mix in water helps in assessing pollution and its impact on aquatic ecosystems.
