.. ... 6 years, 2 months ago

Solid expand on heating because particles of matter loose there original configuration due to thermal energy provided in the form of heating radiation and expand due to vibrational motion of particles in a series. but there are some exceptional property of solid like regalation . ------------------------------------------------------------------------------ Air expands on heating. Why does this happen? It is because the particles of air on becoming warm, move away from each other and take up more space. So we can say that air on becoming hot occupies more space. Since the particles move away from each other, the air becomes less dense and lighter in weight.

Yogita Ingle 6 years, 2 months ago

Processing fibres into wool

Step I: The first step is the removal of the fleece of the sheep along with a thin layer of skin. This process is termed as shearing. The hair provides woollen fibres that are then processed to obtain woollen yarn.

Step II: The sheared fleece is systematically washed in tanks in order to remove the grease, dust and dirt. This is known as scouring.

Step III: The scoured hair is then sorted and sent to a factory where hair of different textures are separated or sorted.

Step IV: Here the small fluffy fibres, called burrs, are separated from the hair and the hair is scoured again and dried. The wool is then ready to be drawn into fibres.

Step V: The fibres are dyed into various vibrant colours because the natural colour of the fleece is black, brown or white.
Step VI: The fibres are then straightened, combed and finally rolled into yarn. The longer fibres are made into wool for sweaters whereas the shorter fibres are spun and woven into woollen cloth.

Sia ? 6 years, 3 months ago

Monsoons always blow from cold to warm regions. The summer monsoon and the winter monsoon determine the climate for most of India and Southeast Asia. The summer monsoon is associated with heavy rainfall. The summer monsoon brings a humid climate and torrential rainfall to these areas. The seasonal rains make it possible for agriculture, forests and inhabitants of the region to store water for the next dry cycle of the climate. The monsoon season also brings lower temperatures to the Southwest.

.. ... 6 years, 2 months ago

Summer monsoons are associated with heavy rainfall.[3] As winter ends, warm winds from the southwestern Indian Ocean flow up towards Southern Asia bringing with it humid climate and intense rainfall. This hot air is caused by the intense radiant heat received from the Sun during its solar maximum in late spring which results in uneven heating of the Earth, and therefore increased winds.[5]
