Question

A physical change can sometimes result in a color change. Which of the following situations shows this?

Answer 1

A physical change can indeed sometimes result in a color change. One common example of this is when a substance is subjected to a physical change that alters its state, such as melting or mixing with another substance.

For instance:
1. **Dissolving a solid in liquid:** When a solid like sugar dissolves in water, the water may become slightly tinted, showing a color change even though the chemical composition of the sugar is unchanged.
2. **Mixing paints or pigments:** When two colors of paint are mixed, the resulting color can be different from the original colors, illustrating a color change due to a physical mixing process.

If you provide specific situations, I can help identify whether they involve a physical change that results in a color change.
