Intext Questions

Question 1.
Are the shape, size, colour and properties of all things same? (Page 19)
No, things are different from each other.

Question 2.
Why we have to make group of things? (Page 19)
We group things according to our utility and comfort that they do not mix with each other.

Question 3.
Have you even thought that why we do not use glasses made of cloth for storage of water? or why things made of paper are not used to fill water? (Page 21)
We cannot use glasses made of cloth for storage of water because clothes have small holes. That is why, water will not be stored in the glass and we won’t be able to fill it. Also, when water is poured on paper, it starts to get leak. Thus, we cannot use things made of paper to fill water.

Question 4.
Which are the important properties of things? (Page 21)
Important properties of things are :

1. Shine/Lustre
2. Hardness
3. Magnetic and non-magnetic
4. Solubility and insolubility
5. Density

Question 5.
You would have seen pin and keys made up of iron get attracted towards magnet. While if we bring pieces of stones, pencil, plastic pens etc. near to a magnet, they do not attract towards it. Why this happens? (Page 23)
Iron is a magnetic material and it is attracted towards magnet, while plastic, wood and stones are non – magnetic materials.

Question 6.
Is an object visible through the mirror? (Page 24)
No, we cannot see an object through the mirror.

Question 7.
What is density? (Page 25)
Density of a substance is its mass per unit volume.

Question 1.
What do you observe?
We observe that pins get attracted towards the magnet while wooden dust does not. Inference – We can say that pins are magnetic and wooden dust is non – magnetic.

Activity – 6 (Page 23)

Question 1.
What will you observe?
We will observe that in beaker B and C, sugar and salt completely dissolve in water and a clear solution is seen while in beaker A and D, sand and chalk powder can be seen at the bottom of beaker.

Inference – It is clear that some things are soluble in water. They are called soluble things like salt, sugar, etc., while things which are not soluble in water are called insoluble things, e.g., chalk powder, sand, etc.

Question 1.
Classify following things on the basis of their compressibility into hard or soft: Sponge, hammer, marble, cotton, rubber, chair, gulabjamun.
Hard-Hammer, marble, chair Soft – Sponge, cotton, rubber, gulabjamun.

Question 2.
Write names of three natural things?
Natural things-wood, water, sand.

Question 3.
What do you mean by magnetic objects?
The objects which get attracted towards magnets are called magnetic objects.

Question 4.
Which property of carbon dioxide made it useful to be used in soft drinks ?
The property of solubility of carbon dioxide makes it useful to be used in soft drinks.

Question 1.
Define transparent, translucent, and opaque objects. Explain with examples.

1. Transparent object – Those objects through which we can see clearly are called transparent objects.
Example – glass and pure air are transparent.
2. Translucent Objects – Those objects through which we can see but not clearly are called translucent object.
Example – Water and plastic sheet.
3. Opeque Objects – Those objects through which we cannot see at all are called opaque objects.
Example – Wood, notebook and the objects made of metals.

Question 2.
Bronze mug loses its shine when kept in open environment. Why?
Bronze is a metal with its particular shine. When bronze mug is kept in open environment for few days, then bronze comes in contact with air and moisture, due to which bronze corrodes. This reduces the shine in bronze mug.

Question 3.
Explain the magnetic properties of a substance with example.
Things which get attracted towards magnets are called magnetic substances. Alpins and keys made up of iron get attracted towards magnet. When we bring pieces of stones, pencil, plastic pens etc. near to magnet, they do not get attracted towards it. Such substances are non-magnetic in nature.

Question 4.
Iron nail sinks in water while paper boat floats on water. Why? Explain.
Generally those things which have density lower than water float on it whereas things with higher den-sity than water sink in it. The density of iron nail is more than that of water, so it sinks. On the other hand, the density of paper boat is lower than that of water. That is why, it floats.

Those things which we get from nature are called natural things.
Example – Wood. Those things which are made by man are called artificial
OR
Example – plastic pen

Question 2.
Give two examples to clarify that things are used according to their properties.
The following examples show that things are used according to their properties.

1. We cannot cook food in utensil made of wood because wood catches fire.
2. We cannot use paper to fill water.

Question 3.
How can we classify things as hard and soft? Explain by giving examples.
Those things which are not compressed easily are called hard objects. For example, a wooden block, a piece of stone. Those things which can be easily compressed are called soft objects. For example cotton, butter.

Question 4.
Classify things on the basis of their property of magnetism. Explain with examples.
According to magnetic properties, things are of two types:

1. Magnetic objects – Those things which get attracted towards magnets are called magnetic objects, e.g., awlpins, iron-nails.
2. Non – magnetic objects – Those things which do not get attracted towards magnets are called non-magnetic objects, e.g., plastic pen and wooden block.

Question 1.
What do you understand by solubility and in-solubility? Explain by giving examples.
Things which get dissolved in water are called soluble things, e.g., salt – sugar etc. While things which are not soluble in water are called insoluble things. For example, chalk power and sand do not get dissolved in water. These properties of objects are called solubility and insolubility respectively. Some liquids, like lemon juice is complete miscible in water while some like kerosene and mustard oil do not get completely mixed in water. Likewise, oxygen gas is partially soluble in water while few gases gets fully mixed in it. Carbon – dioxide is completely miscible in water and hence used in soft drinks.

Question 2.
Write two examples of each ?

1. Compressible – Incompressible
2. Transparent – Translucent
3. Floats – Sinks
