Answer: Option C. -> Hardness
:
C
The properties of materials are the key factorwhile making objects intended for a particular use. Hammers should be made of hard materials to beat the other materials with it. Ironis used for making hammers as metals are generally hard in nature.

Answer: Option B. -> 1-b, 2-a, 3-d, 4-c
:
B
Different objects are made from different materials based on the properties. Chair is made of wood because of its strength. Book is composed of paper because of its ability to be written on. Shoes are also made of leather because of its durability. And we also have cups made of glass because of its texture and heat conductivity.

Properties of liquid substances:
1. Liquids do not have definite shapes; theytake the shape of the container but have a definite volume.
2. The particles of liquids are loosely packed than the particles in solids.
3. They can be compressed to a small extent.
Answer: Option C. -> Vegetable oil will be the uppermost layer, water will be the middle layer and the corn syrup will be the bottom layer.
:
C
The density of corn syrup, vegetable oil and water is in the order:
Corn syrup > Water > Vegetable Oil.
The less dense material will float on top of the more dense material.
Thus, vegetable oil will be the uppermost layer followed by water in the middle and corn syrup being at the bottom layer.

Answer: Option B. -> Kerosene floats above water.
:
B
Kerosene forms a layer above water when boththe liquids are mixed and left to settle for some time. This is because thedensity of kerosene is less than that of water and they do notmix.

Answer: Option A. -> Opaque
:
A
Opaque objectsdo not allow the light to pass through them.
Example:- Wood, Gold, etc.
Tranparent objects allow the light to pass through them while translucent objects partially allow the light to pass through them.

Answer: Option A. -> True
:
A
Grouping can be done based on various parameters such as color, shape, source, etc.The objects given to you are of different shapes so they can be grouped by their shapes like cylindrical, round,irregular, etc.
Similarly, they can be grouped on the basis of colour or materials they are made from.
