Explain breifly all the process of silk production???

Posted by Sneha Prasad 5 years, 3 months ago

CBSE > Class 07 > Science

1 answers

Yogita Ingle 5 years, 3 months ago

Production process. The process of silk production is known as sericulture. ... Extracting raw silk starts by cultivating the silkworms on mulberry leaves. Once the worms start pupating in their cocoons, these are dissolved in boiling water in order for individual long fibres to be extracted and fed into the spinning reel.

Step1: Separation of the silk fibre from the cocoon. For this, it is need to be exposed to warmth.

Piles of cocoons are kept under the sun, boiled or exposed to steam. The warmth causes the silk fibre to separate from the rest of the cocoon.

Step2: Reeling the silk, which is the process of delicately unwinding the fibre from the cocoon. Reeling is also done in special machines.

Step3: The silk thread is then bleached and dyed into many shades.

Write difference between physical and chemical change ?

Posted by Shivam Singh 5 years, 3 months ago

CBSE > Class 07 > Science

2 answers

Sehbaj Brar 5 years, 3 months ago

? Chemical changes are that changes in which new substances are formed ? Physical changes are that changes in which no new substances are formed

1Thank You

Yogita Ingle 5 years, 3 months ago

Physical Change	Chemical Change
When a substance undergoes a physical change, its composition remains the same despite its molecules being rearranged.	When a substance undergoes a chemical change, its molecular composition is changed entirely. Thus, chemical changes involve the formation of new substances.
Physical change is a temporary change.	A chemical change is a permanent change.
A Physical change affects only physical properties i.e. shape, size, etc.	Chemical change both physical and chemical properties of the substance including its composition
A physical change involves very little to no absorption of energy.	During a chemical reaction, absorption and evolution of energy take place.
Some examples of physical change are freezing of water, melting of wax, boiling of water, etc.	A few examples of chemical change are digestion of food, burning of coal, rusting, etc.
Generally, physical changes do not involve the production of energy.	Chemical changes usually involve the production of energy (which can be in the form of heat, light, sound, etc.)
