Jupiter, satern, Uranus and Neptune are all gaseous planets. Jupiter is made of hydrogen and helium. It is also composed of hydrogen and helium. It also has ice os ammonia, ice  of methane and water ice. It has hot, solid inner core made of iron and rocky material. The inner core is surrounded by the outer core that is made up of ammonia, methane and water. The outer core has a layer of thick liquid hydrogen and helium around it. Uranus is a gaseous planet composed of various gases and ice. It has no solid surface. Neptune is the other most gaseous planet with a rocky core.

Anton von leeuwenhoek  was the first person to observe blood, insects etc., under a simple microscope. He described cells and bacteria as seen under a microscope. His microscope was a simple device that used only one lens. The body of the microscope was made of a rass plate. The lens was mounted on a tiny hole in the plate. Leeuwenhoek mounted the specimen on a pin in front of the lens. The microscope was 3-4 inches long. It looked like a modern day magnifying lens. He made several pioneering studies in the field of the life science using this microscope and made 500 microscope during his lifetime. The modern microscope is a very sophisticated instrument that can magnify and give very sharp images. It is known as the compound microscope and uses three lenses: the objective, the eyepiece and the field lens.

Why does the filament in the bulb glow?

          Why does the filament in the bulb glow?

The electric bulb is a glass bulb fitted with a filament that glows when heated by electricity. Thomas alva Edison invented the light bulb.The light bulb consist of a glass bulb.It is a fitted with a filament made of tungsten. The filament is heated to incandescence by passing an electric current through it. The glass bulb is filled with a noble gas that prevent the filament from melting and then evaporating. Many attempts were made to make a bulb before Edison succeeded. The lifespan of the bulb was however approximately 40 hours. Edison conducted many experiment to extend the lifespan of the filament. He finally succeeded in December 1879.
