Explanation:
Fats, steroids and waxes are some of the most common types of lipids. Lipids are non-polar hydrocarbons because of the presence of non-polar carbon-carbon and carbon-hydrogen bonds in there structure.
Generally, polar molecules are soluble in water while non-polar molecules are insoluble in water, hence, lipids do not dissolve in water. There non-polarity also makes them a suitable component in the selectively permeable biological cell membrane.
Electrical conductivity tester.
If the bulb begins to glow brightly when the plug is submerged in the unknown solution then the solution has high conductivity.
The bright glow of the bulb resulting from the experiment indicates that the current flows easily through the unknown liquid.
Batteries, biomass, petroleum, natural gas, and coal are examples of stored chemical energy
