if its for your j cert you get 4 sort of can things cut out 6 strips of fabric[same size] we used old jeans a t shirt and a wool blanket cut them so they bearly over lapped held them on with a rubber band poured 100mls of boiling water into each of the cans [including 1 with on material control] and got the temp put aerobord over the cans 15mins later took the temp again and got the difference done the same for the wet fabric but ran them under the tap hopes you get your A!!!!!!!!!!
What else can I help you with?
Is slate a conductor or insulater?
Slate is primarily an insulator. It is a natural stone composed mainly of clay minerals and has low electrical conductivity, making it unsuitable for conducting electricity. Its insulating properties make it useful in applications like roofing and flooring, where resistance to electrical flow is beneficial.
Is an insulator better when wet?
No, an insulator is not better when wet. In general, moisture can reduce the insulating properties of materials, as water can conduct electricity and facilitate the flow of electrical currents. Wet conditions can lead to increased conductivity, making the insulator less effective in preventing the transfer of electricity or heat.
Why would air add to the insulating ability to fiberglass?
i think you aaa you
Why do electrical tools have insulating handles?
because if you touch a wire you might get electrocuted
Is rubber corn a conductor or a insulator?
Rubber corn, often made from rubber or similar synthetic materials, is an insulator. This means it does not conduct electricity well, making it suitable for applications where electrical insulation is necessary. Its insulating properties prevent electrical current from passing through, which is crucial for safety in various electrical devices.
Is a clothes pin an insulator?
Yes, a clothes pin is not a good conductor of electricity, so it can be considered an insulator. However, its insulating properties may vary depending on the material it is made from.
How are you warmer with several layers of clothes then with a heavy jacket?
Insulating properties is all about how much air the clothes can trap. And several thin layers does this better than one heavy layer.
What materials has both conducting and insulating properties?
Semiconductors.
What are the insulating properties of denim?
denim has great insulating propertires as proved by Irish rockers in winter outside central bank
Is a bottle a good conductor?
Cork exhibits insulating properties. Not conducting.
Is a bottle cork a good conductor?
Cork exhibits insulating properties. Not conducting.
What is a light-sensitive insulating material?
A light-sensitive insulating material is a substance that changes its insulating properties in response to light exposure. It can modify its electrical conductivity, thermal conductivity, or other insulating characteristics when exposed to light. This property is often utilized in optoelectronic devices or photodetectors.
What are the aesthetic properties of wool?
Excellent insulating qualities, water-resistant/wicking (natural oils from the sheep), long lasting (animal protein fiber).
What is a material that can exhibit both insulating and conducting properties?
Graphene is a material that can exhibit both insulating and conducting properties. In its pristine form, graphene is a highly efficient conductor due to its unique 2D structure. However, by introducing defects or doping, graphene can also exhibit insulating behavior, making it a versatile material for various electronic applications.
Why is the insulating properties of neoprene is not needed on a drysuit?
Neoprene is not typically used in drysuits for its insulating properties because drysuits are designed to keep the wearer dry, not warm. Neoprene wetsuits are used for insulation in cold water because they trap a thin layer of water against the skin that warms up to provide insulation. Drysuits use breathable waterproof materials to keep the wearer dry without the need for insulating properties.
Does wetting a j cloth affect its insulating properties?
Yes, whether thermal insulation or electrical insulation, replacing air with water in the voids of a material will affect its insulating abilities.
How can a leaf electroscope be used to test the insulating properties of a given material?
To test the insulating properties of a material using a leaf electroscope, first charge the electroscope by bringing a charged object close to it. Then, place the material to be tested on the electroscope's terminal. If the leaves of the electroscope remain separated, the material is insulating as it does not allow the charge to flow through it. If the leaves collapse, the material is conducting.
