Explain The Life Cycle Of Silk Moth
Life Cycle of Silk Moth The female silk moth lays about 300 to 400 eggs at a time. The eggs hatch and the caterpillars or silkworms emerge. This is called the larval stage. The silkworm feeds on mulberry leaves. The silkworm secretes fine filaments from two glands on its head. The filaments are made of a protein that hardens to form silk fibres when exposed to air. The … [Read more...] about Explain The Life Cycle Of Silk Moth
How ceramics are made?
How ceramics are made? Ceramics:Ceramics are made from clay and composed of aluminium silicate mixed with sand. The white clay used to make ceramics is kaolin which is rich in kaolinite or hydrated aluminosilicate, Al2.O32SiO2.2H20. Red clay consists of iron(III) oxide which gives the red colour. Bricks, tiles, mugs and clay pots are some examples of traditional … [Read more...] about How ceramics are made?
Heat Transfer by Radiation
Heat Transfer by Radiation Heat energy can travel in the form of waves, just like light. These waves (both heat and light, and many other types of waves) are called electromagnetic waves. Energy travelling in this form is called radiation. Just like light can travel - in different media (like air, water, etc.) and in vacuum, heat radiations can also travel in different media … [Read more...] about Heat Transfer by Radiation
