Some materials are hard, lustrous, malleable, ductile, sonorous and good conductors of heat and electricity, called metals. Examples of metals are iron, copper, aluminum, calcium, magnesium, etc. Electrical conductivity in decreasing order as Silver, Copper, Aluminum, Tungsten. Silver is the best conductor of heat and electricity because it contains a higher number of movable atoms (free electrons). Copper is used widely because of low cost than silver and gold.

Which of the following statements is incorrect?

Materials are grouped together on the basis of similarities and differences in their properties. In everyday life, we often group materials for our convenience.

The space between particles is maximum in

In solids, particles are tightly packed. In liquids the space of particles is larger than solids but smaller than gases. The space between particles is maximum in gases. Generally, they are loosely packed.

While doing an activity in class, the teacher asked Paheli to handover a translucent material. Which among the following materials will Paheli pick and give her teacher?

The material through which an object can be seen but not clearly is called translucent material. Hence, muslin cloth is a translucent material. Mirror and aluminum foil are opaque and glass tumbler is transparent material.

Which of the following does not belong to the group?

Water is known as Universal solvent. As it dissolves maximum materials. Ink, milk, honey mixes very well in water whereas oil do not mix with water. Hence, option [D] does not belong to the group.

The property of a substance that decides whether it will float or sink in water is

We can group or identified any materials with the help of density. Generally, density possess some characteristics. As density is the amount of mass per unit of volume. If an object is heavy and compact, it has a high density. So, a simple example is if you have ever tried to mix water and oil. Oil is less dense than water, so it floats on top. A boat also floats for the same reason. And iron or stone are denser than water. Hence, they sink in water.

Which of the following statements is incorrect?

Stones are generally opaque while glasses are transparent.

If you have to select a handle made of different materials for your screwdriver. Which one would you prefer:

I would prefer wood, as it is a non-conductor or insulator of heat and electricity as well as easily workable.

Wood is used as a fuel. Which property makes it suitable for this purpose

The term combustibility refers to the tendency of a substance to burn as a result of fire or chemical reaction. It is can be expressed as a property that is a measure of how easily a substance will ignite or burn.

Which of the materials will you identify as transparent?

Through magnifying glass and glass tumbler we can see the objects clearly so these materials are transparent.

Which of the following will float on water?

Cotton ball initially floats on water but after few minutes it sinks because it absorbs water. All the materials, which are lighter than water, float on water. Wood piece does not sink in any circumstances. Here option [C] will be your answer. So, don’t be confused.

Shopkeeper usually prefer to keep the materials in

Shopkeepers usually prefer to keep biscuits, sweets and other eatables in transparent containers of glass or plastic, so that buyers can easily see these items. And container saves the product from attack of fugus, dust and foreign materials.

Those substances or materials through which things can be seen are called

Substances through which things can be seen are called “transparent” substances. Example glass, water and air. Substances through which things can be seen but not clearly are called “translucent” substances. Example oiled paper, muslin cloth. Materials through which things cannot be seen are called “opaque” substances. Example wood, metals etc.

In appearance, materials have different properties like

The appearance of the material deals with the look, texture and feel. In addition to lustre, colour, shape, quality and states (solid, liquid, gaseous, plasma) defines the property of appearance of the material. Hence, option [D] will be your answer.

Pick one material from the following, which is completely soluble in water

Glucose is completely soluble in water because its particles are so small and spread uniformly in water that we cannot see them. But chalk powder, tea leaves and sawdust are insoluble in water and settle down at the bottom of the container.

Strongest intermolecular force of attraction founds in

In solids, particles are tightly packed. In liquids the space of particles is larger than solids but smaller than gases. The space between particles is maximum in gases. Generally, they are loosely packed. Hence, intermolecular force attraction found strongest in solids, weaker in liquids and weakest in gases.

Our palm is a example of

Materials through which things cannot be seen are called “opaque” substances. Example wood, metals etc. Our palm and most of body parts are opaque. But when it (flesh, skin, cartilages, nerves) kept in powerful light source, it behaves like “translucent”. But still, the X-ray light source is not able to cross the bone of our body.

Which of the following statements is incorrect?

In everyday life, we often group materials for our convenience. But we usually store things in a manner that similar materials make a separate group and such an arrangement helps us to locate them easily. Hence, at home, we usually store things in such a manner that objects are easily separated in a group.

There are given some name of the objects. Pick out the odd ones

All are rounded eatable objects, except basket-ball. Hence, option [D] will be your answer.

In which of the statement is incorrect?

Water is known as Universal solvent. As it dissolves maximum materials. But oil, chalk, sawdust and sand are not dissolved in water.

An iron nail is kept in each of the following liquids. In which case would it lose its shine and appear dull?

An iron nail kept in soft drink would lost its shine and appear dull become soft drink contains carbonic acid which reacts with iron nail, so it gives dull appearance. Iron nail has no reaction with mustard oil, coconut oil and kerosene, so does not lose its shine, when kept in these solutions.

Boojho asked a question to Paheli that which of the following is a good conductor of heat? Would you help her?

Among of these, here graphite (non-metal) is a good conductor of heat.

Find the odd-one out from the followings

Tawa, spade and pressure cooker are all hard materials i.e. cannot be easily compressed, cut, bent (molded) or scratched but eraser can be easily cut, bent or scratched. So, the odd one is eraser.

Why clay is used for making pots and bricks?

The property of substances by which they can be beaten into thin sheets is called malleability. Bricks, pots and many other things is made by soil as a form of wet clay. Wet clay has the property of malleability and bricks are burned in a kiln which makes them durable.

In generally, we have seen iron rods present in windows. Because of which properties of metal, we use it?

We know that some materials are hard, lustrous, malleable, ductile, sonorous and good conductors of heat and electricity, called metal. Iron is very hard and strong metal and it is found everywhere and relatively cheaper than any other metals. Therefore, we use an iron metal or rod in window as well as door lock.

Which type of the following materials is used for making the front glass (windscreen) of a car?

Those substances through which things can be seen are called “transparent” substances. Example glass, water and air. Transparent material is used for making the front glass (windscreen) of a car.

Boojho wants to know the name of the instrument, which is used to measure the density of liquids?

A hydrometer is an instrument used to measure the specific gravity or relative density of liquids, i.e. the ratio of the density of the liquid to the density of water. A barometer is a scientific instrument that is used to measure air pressure or atmospheric pressure in a certain environment. A hygrometer is an instrument used to measure the amount of humidity and water vapour in the atmosphere, in soil, or in confined spaces. An ammeter (from Ampere Meter) is a measuring instrument used to measure the current in a circuit.

Which of the following statements is not true?

Materials are grouped for our convenience and to make it convenient to study their properties. Materials are also grouped according to their uses. So, only statement [C] is not true.
