LIQUID CRYSTALS Introduction What are Liquid crystals ? Its History & Discovery Any of various liquids in which molecules are regularly arrayed like a solid crystal along one or two dimensions‚ but are free in the other dimensions as with typical liquids. Liquid crystals often display unusual and often manipulable optical properties such as anisotropic scattering. They can be divided into two classes‚ Thermo tropic(nematic‚ chiral nematic‚ and smectic.) and Lyotropic. Transitions to thermotropic

The question I will be investigating is on how fast ice melts in different liquids. The liquids being tested are water‚ salt water‚ hydrogen peroxide‚ and Pepsi. The ice will be placed in each of these liquids when the liquids all reach room temperature. Some people assumed that Coca Cola would melt the ice the fastest because of it’s carbonation. But when tested they found that at room temperature water melted the ice the fastest(2). Another person tested how fast water‚Sprite‚ and orange juice

Are we too dependent on computers? When we talk about computers‚ people often relate computers with modern technologies. Computer is a tool that helps us make things in our life easier. People use computers in business‚ public services‚ educations‚ even entertainment. Our daily activities are more and more based closely on the working of computer. Almost everything we do is affected by modern technology and computers. I would say that I agree that people nowadays depend on computers too

Materials in nature can be divided into different phases‚ also called states of matter‚ depending on the mobility of the individual atoms or molecules. The obvious states of matter are the solid‚ the fluid and the gaseous state. In the solid state‚ intermolecular forces keep the molecules close together at a fixed position and orientation‚ so the material remains in a definite shape. In the fluid state‚ the molecules are still packed closely together‚ but they are able to move around. Hence a fluid
