Three polymers are given below silk, rubber, PVC. Categorise each under separate heading based on intermolecular forces.

The following are the names of certain polymers Neoprene, Nylon, Polystyrene, silk, PVC, Bakelite. classify the above polymers based on the intermolecular forces

Polymers are classified into elastomers, fibres, thermoplastics and thermosetting plastics, depending upon the intermolecular forces. Fill in the vacant boxes given below:

Some polymers are given below: Nylon-66 .Name the monomer present in each polymer and Identify the type of polymerisation involved in it.

Among cellulose, polyvinyl chloride, nylon and natural rubber, the polymer in which the intermolecular force of attraction is weakest is

Nature of some images are given below. Find out the real and virtual images and then write it in separate column. Inverted image , Do not obtained on a screen , Obtained on a screen , If the light rays really intersect to each other , Erect image , The image distance cannot directly.

Classify the diseases given below into two groups based on the causative organism of each group (Typhoid, Malaria, Diphtheria, Amoebia).

Read the following statements carefully and select the appropriate option given below. (i) Bisexual animals that possess both male and female reproductive organs, are hermaphrodites. (ii) In seed plants, pollen grains are the carriers of male gametes and ovule have the egg. (iii) Events in sexual reproduction before the formation of zygote are called post-fertilisation events. (iv) Sexual reproduction involves the formation and fusion of gametes, (v) Animals are categorised into oviparous and viviparous based on whether the development of the zygote takes place outside the body of the female parent or inside.
