Howmany types of nonmetals

Answer»

Ferrous metals.
Non-ferrous metals.
Noble metals.
Heavy metals.
Metal alloy
Ferrous metals: As the name INDICATES these are the metal combination of Iron with carbon. Since it has various varieties and large scale use, it is categorized as ferrous metals. The ferrous metal is very hard and can be made into a different shape. types of metals

The strength is very high such that it is used in making heavy machinery and equipment. Even it can withstand heavy weights and harsh environmental conditions. They undergo corrosion with time and can melt at very high temperatures.



These metals are good conductors of heat and also electricity. Ex: iron, steel.

Non-Ferrous metals: These are the metals which are used instead of iron for machinery and other equipment. They are not so heavy as ferrous metals. And even they are less corrosive and softer than them. They need less pressure to mold into any form.

They are in high demand these days due to above advantages. Ex; Aluminum, lead, copper.

Like ferrous metals, they are also good conductors of heat and electricity.

Noble metals: Like noble gasses, these metals are less reactive. Of course, they react in liquid or powder forms. But in general, they do not corrode and rust on exposure to air. They are soft and can be easily molded into different forms. They are quite expensive due to above properties and are used in jewelry, coin making etc. Ex; Gold, platinum, silver.

They are the good conductors of heat and electricity. Maybe they are even better than other metals in this regard.



They are also highly malleable. I.e. they can be beaten into a very fine sheet. Gold of 1gm can be beaten into a sheet of 1-meter square. Gold foil was used by Rutherford to study the atomic structure.

Heavy metals: These are the metals with high atomic weight and high density. But they can be less stronger than iron and other metals. They are not WIDELY present in nature like other above metals. But they can be accumulated. Even they are toxic to human health when taken internally. Ex: Arsenic, cadmium, lead.

Metals we generally think are hard substances and can be molded to shapes but not all of them are so. The heavy metals mentioned above do not follow this rule. Also, metals are good conductors of heat and electricity. Interestingly not all do so. Mercury is a bad conductor of heat while lead is a bad conductor of electricity.

Metals have MANY uses in industry, agriculture and even in the health sector. They are even part of few BIOMOLECULES in plants and animals.

Metal alloys: These are metals which are made of combination of metals. They are alloyed (mixed) to get desired properties like greater strength, durability and also resistance to corrosion. Also these metals alloys are used to avoid or RESIST heat generation. For example in large gun cannons. Since during firing, they get hot, these alloys are made so that they do not get heated so fast like the traditional metals.

An object has a velocity of 8 m/s and a kinetic energy of 480 J. What is the mass of the object? (Formula: )7.5 kg15 kg60 kg120 kg

Answer»

Hey there!!

Here is your answer ↓↓

In ORDER to find the mass, when kinetic ENERGY , VELOCITY is GIVEN, we use this formula :

Kinetic Energy = ( 1 ÷ 2 ) ( m ) ( v² )

m = mass

v = velocity ( 8 m/s )

Kinetic energy = 480 J

480 = ( 1 ÷ 2 ) ( m ) ( 8² )

480 = ( 1 ÷ 2 ) ( m ) ( 64 )

480 = 32m

m = 480 ÷ 32

m = 15

The mass is 15 kg

Hope my answer helps!

Which are various medai of spreading the infectious disease

Answer»

There are THREE main ways by which infectious diseases can be spread. They are:


1. Through Physical contact: When a person suffering from an infectious disease has some physical contact with ANOTHER person then the infectious disease can spread through contact.


2. Through Air : If a person suffering from cold is found to be SNEEZING near a healthy person, then the cold can spread to that healthy person also as cold is a contagious and an infectious disease.


3. Through other vectors : Vectors such as Mosquito, houseflies, etc can transport impurities along with diseases from ONE person to another. If a mosquito sucking blood from a person suffering from malaria, sucks blood from a healthy person also, then there are chances of malaria to be transmitted to that healthy person.


Hence we must be safe and also must use some things LIKE Handkerchiefs, mask, etc. to avoid transfer of diseases.


These are the various ways of spreading infectious diseases.

Metals and non metals chapter class 8 notes atleast of 3 pages

Answer»

Everything around us can be categorized into two types of elements- metals or non-metals. Take a look…your book, your clothes, your pencil, your water bottle, your bag, the blackboard, the door and EVEN your tiffin and the contents of it! Complex yes, but when broken down to its most basic form, on the basis of their physical attributes and chemical makeup, everything is either a metal or a non-metal. So, in Class 8 studying the functionalities of Metals and Non-Metals is very important.

Thus, it is very important to know what metals and non-metals are and how to distinguish between them.

Getting to know the periodic table

The periodic table is an arrangement of elements on the basis of certain chemical properties. In a row, generally, the metals are arranged on the left side and the non-metals on the right side. Table rows are periods and columns are called GROUPS. Note that there are 92 elements that occur naturally out of which 70 are metals and 22 are non-metals.

Metals

As you can see from the above depiction of the periodic table, most of the elements are metals. There are various kinds of metals

alkaline earth metals,

alkali metals,

transition metals,

actinides, and

Lanthanides

Metals on the left-hand side of the periodic table are DISTINGUISHED from non-metals on the periodic table by a zigzag line that starts from carbon and runs down phosphorus, selenium, IODINE, till radon. Therefore these chemical elements and everything on their right is non-metal and the row just to their left is known as semi-metals or metalloids. They have the combined properties of both metals and non-metals

39.

What type of mixture can be separated by the process of distillation

Answer»

The CONSTITUENTS of a HOMOGENEOUS liquid-solid MIXTURE in which solid is soluble in other.
like water and salt

Why level of Mercury don't fall in clinical thermometer

Answer»

The thermometer is not full of mercury and air, it only has mercury. The air was excluded from inside of the thermometer during the manufacturing process. Where mercury isn’t, there is a near perfect vacuum. This means there is no gas pressure above the mercury to push the mercury BACK down and no gas pressure keeping it from flowing down into the bulb. Liquids in an evacuated glass tube act much differently that they do with air in them. Seal a larger diameter tube with some mercury in a vacuum and tip the tube. The mercury will run down the tube and hit the sealed end with such force that the glass will break like you hit it with a hammer. There is no air to cushion the mercury at the end. If it does not break, it feels like …. well someone hit the end with a hammer. It’s a very odd feeling.Mercury and other liquids have a property called surface tension. This is an atomic level attraction between atoms and molecules. Mercury’s surface tension is very HIGH. A drop on a table will contract into a tiny sphere with a flat bottom caused by gravity acting against this force.

So the constriction at the bottom is small enough that the force of surface tension wins over gravity, but just BARELY. Shaking, or more precisely, applying centripetal force, in addition to gravity, together wins over surface tension and the mercury is FORCED back together with the larger reserve in the bulb. This would not be possible if any air were in the tube separating the two.

I’ve never though of this before, but it is likely a mercury thermometer would not work PROPERLY in orbit. You might not be able to shake the thermometer hard enough, and might have to put it into a centrifuge to reset it.
