How do you check petrol adultaration?
To check for petrol adulteration, you can perform a simple water test: take a clear glass container and add a small amount of petrol, then slowly add an equal amount of water. If the petrol is pure, it will float on top and remain separate, while adulterated petrol may mix with water or leave a colored residue. Additionally, you can check for a strong chemical smell or unusual color, which may indicate the presence of other substances. For more accurate results, consider using a testing kit specifically designed for fuel analysis.
What residue does smoke leave when it is filtered?
When smoke is filtered, it leaves behind a residue primarily composed of tar, ash, and other particulate matter. This residue contains various harmful compounds, including carcinogens and toxins, that can contribute to health issues and environmental pollution. The composition of the residue can vary depending on the source of the smoke, such as tobacco, wood, or other materials. Overall, filtering reduces but does not eliminate the harmful components present in smoke.

When methanol is burned and leaves a residue a physical or chemical change?
