Air is better than thermocol as insulator. .....
Ceramic is the best insulator among these materials due to its ability to withstand high temperatures and resist conductive heat transfer. It is also non-reactive and has low thermal conductivity, making it ideal for insulating applications.
Na is the best insulator among Na, Si, and S. This is because Na is a metal and tends to have very low conductivity compared to Si and S which are semiconductors or nonmetals with higher conductivity.
Distilled water is the best insulator of electricity among the options provided. This is because it is a pure form of water without any impurities or minerals that can conduct electricity. Copper and aluminum are conductive materials, while tap water contains impurities that can make it conductive.
Waxed paper is a better insulator than plastic cups because it is generally thicker and has a lower thermal conductivity. Waxed paper traps heat better, making it a more effective insulator for maintaining the temperature of liquids.
Air is the best insulator among silver, copper, iron, and air. This is because air has a lower thermal conductivity compared to the metals silver, copper, and iron. Insulators with low thermal conductivity are better at reducing heat transfer.
Aluminum will conduct both electric current and heat, so it would be a bad insulator of either.
wool i think.
From best to worse, it would be glass, plastic, cotton and iron.
If I had to choose the best insulator out of steel wool, aluminum foil, cotton and bubble wrap, I would choose the aluminum foil.
When thermocol is burnt, it releases toxic fumes and black smoke, including styrene gas, which is harmful to health and the environment. It is not a safe practice to burn thermocol as it can lead to air pollution and respiratory issues. It is best to dispose of thermocol using proper recycling methods.
Bubble wrap is the best sound insulator out of cardboard, cotton wool, and bubble wrap. It is lightweight and has air pockets that help to absorb sound vibrations effectively. Additionally, bubble wrap is durable and can be easily applied to different surfaces for soundproofing purposes.
wool insulates heated water best because woll is the best insulator.
Copper - best conductor Glass - moderate insulator Rubber - good insulator
Oxygen. Carbon as diamond is a good electrical insulator, (graphite is an electrical conductor), silicon is a semiconductor so has limited electrical conductivity and aluminium is a metal and a good electrical conductor.
aluminium foil because it has the qualities of metal and tin which are good heat conservers.
oxygen.is the best insulator
Acrylic paint will give the best look. U can use water color also.
