Base and Alkali

-Base is defined as a substance that can neutralise acids to form salt and water.

-A base which is soluble in water is known as an alkali

-An alkali is a substance that ionises in water to produce hydroxide ions,OH-.

For example,sodium hydroxide,NaOH is an alkali as it dissociates in water to form hydroxide ions in the following manner:

NaOH(s)>Na+(aq) + OH-(aq)

- An alkali has the following physical properties:

*bitter taste

*slippery feel

*pH higher than 7

*turns red litmus paper blue

*conducts electricity

Wave Motion

-Waves are energy carriers.

-Energy can be transferred from one place to another by progressive or travelling waves.

-Waves that do not appear to move are called stationary or standing waves.

-There are two types of waves.

(a)Mechanical waves

-Waves transmitted through medium by particle vibrations.

(Example: Sound waves)

(b)Electromagnetic waves

-Waves transmitted through electromagnetic fields by oscillations of electric field and magnetic field.

(Example: Light)

Understanding Gas Pressure and Atmospheric Pressure

Gas Pressure

-Gas particles in a container are in continuous random motion.

-They collide with the walls of the container and bounce back.

-The gas pressure in the container is a result of the force exerted on the walls by the gas particles during the collisions.

Atmospheric Pressure

-Earth is surrounded by a thick layer of atmosphere.

-Atmospheric pressure is the pressure exerted by the weight of the atmosphere,at any point,on the earth's surface.

-Atmospheric pressure acts in all directions.

-Atmospheric pressure decreases with increasing altitude.
