INSULATORS:Insulators work as protectors. They MAY protect heat, sound and the passage of electricity. THERMAL insulators, sound insulators and ELECTRICAL insulators are used for various reasons, from keeping HOUSES warm to protecting electrical wires and SOUNDPROOFING roomsExplanation:please thanks me

is the DEFINITION of SIMPLE WORD

Tsvet and Early Column ChromatographyIn the 1890s, column fractionation was developed as a technique to separate out the DIFFERENT COMPONENTS of petroleum. ... As a RESULT, he NAMED the technique “CHROMATOGRAPHY”; “chroma” from the Greek word for “colour”, combined with “graphy”, meaning writing or recordin

It has low melting POINT and so it MELTS faster even at ROOM temperature.Explanation:It becomes solid when temperature increases. So it is a Physical change.

Can you SEND me its PICTURE

Definition:-Conduction of heat OCCURS when MOLECULES increase in temperature; they vibrate, and this vibration and movement passes the heat ENERGY to the surrounding molecules. Examples of conduction of heat accidentally touching a hot pot, or when a heating PAD is applied to you directly and warms your muscles

tion:Sodium, Lithium, potassium reacts with oxygen, so it has to be kept AWAY from air. Storing it under a LIQUID is an easy way to do that. Water is our usual go-to liquid, but sodium reacts with water (and also floats on top, because it’s less dense than water), so water is not a good choice. Sodium also reacts with alcohols, so those are no good. It does not react with hydrocarbons, and is denser than all the ones I can think of, so they are a good choice. Kerosene is cheap, pretty non-toxic, does not evaporate as fast as some hydrocarbons, and so is a pretty good choice.However, for long-term STORAGE, MINERAL oil is preferred, since kerosene will evaporate eventually if the CONTAINER is not perfectly sealed.

ᎻᎬY ᎷᎪᎢᎬ ᏌᎡ ᎪNᏚᏔᎬᎡ ᏆᏚA CANDLE wick works by capillary action, conveying ("wicking") the fuel to the FLAME. When the liquid fuel, typically melted candle wax, REACHES the flame it then VAPORIZES and combusts. The candle wick influences how the candle burns.

it's false because EXPLANATION: that are more reactive than hydrogen displace it from dilute ACIDS. For example: sodium and potassium. METALS that are less reactive than hydrogen do not displace it. For example: copper HOPE it will help you mark me as BRILLIANT

because there can be USEFUL THINGS

Synthetic polymers are human-made polymers derived from petroleum OIL. From the utility POINT of VIEW they can be classified into three main categories: thermoplastics, elastomers and synthetic fibers. They are found commonly in a variety of consumer products such as HONEY, glue, etc.EXAMPLE EXAMPLES of synthetic polymers include nylon, polyethylene, polyester, Teflon, and epoxy.

Here is your AnswerExplanation:The specific conductance (κ) is the PRODUCT of cell CONSTANT (  al​   ) and reciprocal of RESISTANCE (  R1​   ).  Hence,  al​   =κ×R=2.768×10  −3 OHM  −1 cm  −1 ×82.4ohm=0.2281cm  −1 .

tion:It is an ionic compound, because it is made of a METAL ION, sodium (Na+), that is attracted to a non- mental ion, hydroxide (OH-). When it is a solid it is WHITE and it has a high MELTING point of 604.4F. Though it has a high melting point, sodium hydroxide dissolves in water extremely well.HOPE THIS HELPS YOU¶ THANK YOU ¶PLEASE MARK AS BRAINLIEST ™®

tion:Material and COLOR does effect rate of absorption, emission and REFLECTION of heatIf the surface is shiny such as a metallic surface, then such surface absorb radiation slowly rather they reflect more. Similarly, if we have a white COLORED surface, it will also absorb least amount of raidation. In CONTRAST, if we have a black colored surface, then this would emit as well as absorb radiation more effectively

in SEPARATION of WATER and ethanol USING FRACTIONAL distillation the water will BECOME the distilliate

mple, liquid ethanol can be SEPARATED from a mixture of ethanol and water by FRACTIONAL distillation. This METHOD WORKS because the liquids in the mixture have different boiling points. When the mixture is heated, one liquid evaporates before the other

There are way in separating mixtures of chloride salts such as that of sodium chloride and ammonium chloride. It can be done by crystallization, FILTRATION, and sublimation. The easiest method among the THREE is separation by sublimation. Ammonium chloride sublimes upon heating. Actually, the sublimation is a decomposition of ammonium chloride forming AMMONIA and hydrogen chloride. Sodium chloride, on the other HAND, doesn't sublime and has a higher melting point than ammonium chloride. If we want to separate the mixture, we have to heat up to 330-350 degrees Celsius and collect the gas that will be produced. PLEASE MARK ME AS BRAINLIEST

tion:The clothes which we WEAR are made of fabrics. Fabrics are made from fibres obtained from natural or artificial sources. Can you name some natural fibres? Fibres are also used for making a large variety of household articles. Make a list of some common articles made from fibres. TRY to separate them into those made from natural fibres and those made from artificial fibres. Make entries in Table 3.1.Table 3.1 : Natural and artificial fibresS. No. Name of Article Type of Fibre (Natural/ artificial)Why did you label some fibres as artificial?You have read in your previous classes that natural fibres like cotton, WOOL, silk, etc., are obtained from plants or animals. The synthetic fibres, on the other hand, are made by human beings. That is why these are called synthetic or man-made fibres.3.1 What are Synthetic Fibres?Try to recall the uniform pattern found in a necklace of beads joined with the help of a thread [Fig. 3.1(a)]. Or, try to join a number of paper clips together to make a long chain, as in Fig. 3.1 (b). Is there any similarity between the two?A synthetic fibre is also a chain of small units joined together. Each small unit is actually a chemical substance. Many such small units combine to form a large single unit called a polymer. The word ‘polymer’ comes from two Greek words; poly meaning many and mer meaning part/unit. So, a polymer is made of many repeating units.Polymers occur in nature also. Cotton, for example, is a polymer called cellulose. Cellulose is made up of a large number of glucose units.3.2 Types of Synthetic FibresA. RayonYou have read in Class VII that silk fibre obtained from silkworm was discovered in China and was kept as a CLOSELY guarded secret for a long time. Fabric obtained from silk fibre was very COSTLY. But its beautiful texture fascinated everybody. Attempts were made to make silk artificially. Towards the end of the nineteenth century, scientists were successful in obtaining a fibre having properties similar to that of silk. Such a fibre was obtained by chemical treatment of wood pulp. This fibre was called rayon or artificial silk. Although rayon is obtained from a natural source, wood pulp, yet it is a man-made fibre. It is cheaper than silk and can be woven like silk fibres. It can also be dyed in a wide variety of colours. Rayon is mixed with cotton to make bed sheets or mixed with wool to make carpets.

Every COLLOID consists of TWO parts: colloidal particles and the dispersing medium. The mixture of sand and water is an example of suspension. ... The Tyndall EFFECT is the scattering of light as a light beam passes through a colloid. The INDIVIDUAL suspension particles scatter and reflect light, MAKING the beam visible.
