Q. What are some examples of good insulators?
Examples of insulators include plastics, Styrofoam, paper, rubber, glass and dry air.
Q. Why is water a good insulator?
Water readily absorbs and transmits heat. pUre water does not contain any acid or salts or other impurities in it , SO we can say that pure water acts as insulator. AS we know that , insulators are those materials which does not allow electric current to pass through them easily.

Q. Which materials are good conductors and which are good insulators?
Review
- Conductors conduct electrical current very easily because of their free electrons.
- Insulators oppose electrical current and make poor conductors.
- Some common conductors are copper, aluminum, gold, and silver.
- Some common insulators are glass, air, plastic, rubber, and wood.
Q. What materials make good insulators and why?
Insulators do this by slowing down the loss of heat from warm things and the gaining of heat by cool things. Plastics and rubber are usually good insulators. It is for this reason that electrical wires are coated to make them more safe to handle. Metals, on the other hand, usually make good conductors.
Q. Which metal is the best insulator?
As you can see, out of the more common metals, copper and aluminum have the highest thermal conductivity while steel and bronze have the lowest.
Q. Is stainless steel a good insulator?
Titanium and its alloys have extremely low thermal conductivity. It also tends to be extremely resistant to corrosion. Stainless steel is also a good insulator, though not as good as Ti.
Q. Does aluminum heat up faster than steel?
It takes more energy (heat) to expand the Aluminum’s temperature by one degree than it would to build the Steel’s temperature by one degree. Heats up faster, steel or aluminum:- Aluminum led heat the quickest; steel gave off an impression of being the slowest.
Q. Is water an insulator?
Well actually, pure water is an excellent insulator and does not conduct electricity.
Q. Is gold an insulator?
Gold is a poor insulator and a good conductor, having a resistivity of 22.4 billionths of an ohm-meter. As with lead, gold is widely used to make electronic contacts. Unlike many other metals, it is very chemically stable and resists the corrosion that degrades other types of electrical connectors.
Q. Is salt water an insulator or conductor?
This is because salt water is a good conductor of electricity which makes ocean water a resource for renewable energy. Salt molecules are made of sodium ions and chlorine ions. When you put salt in water, the water molecules pull the sodium and chlorine ions apart so they are floating freely.
Q. Is milk a good conductor of electricity?
Milk is a good conductor of electricity because it contains water and lactic acids and other salts.
Q. Is coconut water good conductor of electricity?
No. Coconut oil is a non polar liquid (when liquid) and does not have any free electrons which can move when you apply a potential (voltage) across it. Water is a polar solvent and contains free ions which can move depending on the potential applied (and hence conduct electricity).
Q. Is cooking oil a good conductor of electricity?
The liquid (vegetable oil) allows the electric current to pass through. Since, it is a good conductor of electricity. Oil is an insulator and is a bad conductor of electricity. …
Q. Does vegetable oil is good conductor of electricity?
Vegetable oil is a poor conductor of electricity. It does not conduct electricity. Vegetable oil are not necessarily “good” conductors of electricity but yes they will conduct electricity. Most things conduct electricity at some level, they may have high resistance but they will still conduct electricity.
Q. Why is vegetable oil a poor conductor of electricity?
Vegetable oil is a poor conductor of electricity. It does not conduct electricity. Oil does not have electrons which can move when energy is applied.
Q. Is glucose solution a good conductor of electricity?
Typically, nonelectrolytes are primarily held together by covalent rather than ionic bonds. Glucose (sugar) readily dissolves in water, but because it does not dissociate into ions in solution, it is considered a nonelectrolyte; solutions containing glucose do not, therefore, conduct electricity.
Q. Why is glucose a bad conductor of electricity?
When glucose is added to water it readily dissolves but it does not dissociate into ions. Therefore, the glucose solution is a non-electrolyte and is a poor conductor of electricity.
Q. Is glucose acidic or basic?
Glucose has neither an acidic nor a basic nature. It is considered neutral, and its pH value is 7 .
Q. Why alcohol and glucose are not acid?
Result: The solution of glucose and alcohol do not give up H+ions in their solution forms, hence they are not classified as acids.
Q. Is glucose and alcohol are acid?
Compounds such as alcohols and glucose also contain hydrogen but are not categorised as acids.
Q. Why does alcohol show acidic property?
Acidic character of alcohol – definition The acidic character of alcohols is due to the electronegative oxygen atom which withdraws the electrons of the O-H bond towards itself. As a result, the O-H bond becomes weak and hence a proton can be easily abstracted by a strong base.
Q. Why alcohol is bad conductor of electricity?
The liquids conduct electricity only if they can produce ions in the solution. Alcohol does not dissociate into ions, thus is a bad conductor of electricity.
Q. Is wine a conductor?
Wine will conduct electricity more than pure water will. In liquids electricity is transported by postive and negative ions. In pure water a small proportion of the water molecules are split into a positively charged hydrogen ion and a negatively charged hydroxyl ion.
Q. Is hand sanitizer electrically conductive?
Some ingredient list is vague whereas some are very precise, and yet some are extremely long. Whichever the case, we are still unclear if there is any electrically conductive material inside the hand sanitizer. Just don’t spray your device with hand sanitizer. It might cause a short-circuit.
Q. Can I use hand sanitizer to clean my phone?
Alcohol-free hand sanitisers (avoid household cleaners, even if they’re alcohol-free) should be fine to use on exposed screens, so long as they are effective against both viruses and bacteria. They’re the quickest and easiest way to keep your smartphone virus and bacteria free and some come in handy foam form too.
Q. Does hand sanitizer damage electronics?
Or, many experts say, never use rubbing alcohol. And never hand sanitizing gel, which tech experts say can damage your devices. Washing your hands properly and frequently, of source, is also part of the equation.
Q. Can you use hand sanitizer as a conductive gel?
No, you don’t need any specific conductive gel. Most people use hand lotion, aloe vera gel, hand sanitizer gel, etc. Because the electrode part of the ear clips are metal, you just need something liquid to enable conducting comfortably between the ear clips and your ear.
