They can help identify colloids, a type of mixture in which one substance is dispersed evenly throughout another in the form of small particles, like milk, smoke, fog, etc. When you shine a bright light through a colloid, the light will scatter (like when you shine a flashlight through smoke), a phenomenon known as the Tyndall effect.

What are two tests you can use to determine if a mixture is a solution or a mechanical mixture?
To determine if a mixture is a solution or a mechanical mixture, you can use a filtration test and a visual observation test. In a filtration test, a solution will pass through a filter without leaving residue, while a mechanical mixture will leave solid particles on the filter. For visual observation, a solution appears homogeneous and clear, while a mechanical mixture shows distinct phases or components that can be seen separately.
Do flashlights contain or use mechanical energy?
No, flashlights do not typically contain or use mechanical energy. Instead, they use electrical energy to power the light-emitting components, such as the light bulb or LED. The electrical energy is converted into light energy by these components.
