Distillation is a process of separating components of a liquid mixture based on their different boiling points.
Distillation involves heating a liquid mixture to vaporize the more volatile components.
The vapor is then cooled and condensed back into a liquid, separating it from the less volatile components.
The separated components can have different boiling points, allowing for purification or concentration of specific s...
Distillation is a process of separating components of a mixture based on their boiling points.
It involves heating the mixture to vaporize the component with the lowest boiling point.
The vapor is then condensed and collected as a separate liquid.
This process can be used to purify liquids, separate different components of a mixture, and extract essential oils from plants.

The value of water pH indicates its acidity or alkalinity.
Water pH is a measure of how acidic or alkaline the water is.
The pH scale ranges from 0 to 14, with 7 being neutral.
A pH below 7 indicates acidity, while a pH above 7 indicates alkalinity.
Pure water has a pH of 7.
Different substances can affect the pH of water, such as pollutants or minerals.
40% of 800 is 320.
Calculate 40% of 800 by multiplying 800 by 0.4.
40% of 800 = 800 * 0.4 = 320.
1 kilogram is equal to 0.001 metric tons.
1 kilogram = 0.001 metric tons
To convert kilograms to metric tons, divide by 1000
Example: 5 kilograms = 5 * 0.001 = 0.005 metric tons
pH scale is a measure of acidity or alkalinity of a solution on a scale of 0 to 14.
pH below 7 indicates acidity, with 0 being the most acidic
pH above 7 indicates alkalinity, with 14 being the most alkaline
Pure water has a pH of 7, considered neutral
