Generating Electricity

Presentation - 10 pages - Physics

The blade of a turbine is tilted an angle. Movement of the air is channeled creating low and high pressures on the blade that force it to move. The blade is connected to a shaft which in turn is connected to an electrical generator. The mechanical energy of the turning blades is changed into...

Ka and Buffer Titrations

Case study - 2 pages - Physics

As living things, we are highly sensitive to changes in our environment; this doesn't only mean changes outside our body, but changes from within also. For the cells in our bodies to function properly a certain temperature and pH has to be maintained. Even a slight change in pH inside our bodies...
