Four Autobiographical Responses Because we listen autobiographically‚ we tend to respond in one of four ways.

These responses come naturally to us. We are deeply scripted in them; we live around models of

such as sodium vapour lamp‚ mercury vapour lamp‚ neon gas lamp. 2) Those which use the phenomenon of fluorescence and are known as fluorescent lamps. In these lamps‚ the discharge through the vapour produces ultraviolet waves which cause fluorescence in certain materials called the phosphorus. The inside of lamp is coated with phosphor which absorbs invisible ultra-violet rays and radiates visible rays. Example: Fluorescent mercury-vapour lamp. High pressure mercury vapour lamp:

weight greater in air than in the liquid. Therefore‚ it is easier to lift a body in a liquid than in the air. ii. Steel balls sink in water but don’t sink in mercury. Why? ~ The density of the water is less than that of mercury. Also‚ the density of the steel is greater than that of water but less than that of mercury. Hence‚ mercury provides greater upthrust than water does resulting the floatation of the steel in it. iii. A body floats in a liquid contained in a beaker. The whole system

more than a century. In fact‚ the first written record of amalgam being used in dental applications is 1528 .Yet‚ it is still a very commonly used material today. Amalgam was first made by melting down Spanish or Mexican coins and mixing them with mercury . When it cooled and settled into the cavity‚ it actually turned black. Bell then evolved this rudimentary procedure into a more controlled alloy in 1819. The substance created a massive wealth for the dental surgeons who promoted its use. However
