What is Entropy ?!!

My discussion ... 

- Entropy measures the ability of molecules and paricles network shape and order change ... !!

as much as molecules can be disordered and change places and more freely to move .. as much as high

Entropy !!



- The more system is shaped ... the more entropy it has ...

- Liquid >>> Gas  ............. low entropy to high entropy .............. change of entropy >>>  +ve !! 

- Solid >>>>Liquid  ..........low entropy to high entropy .............. change of entropy >>>  +ve !! 



Entropy increase when ... : 

Something dissolved ....

Temperature Increase ....

Gas Formed ...

More Moles Formed ....

As presseure decrease ... entropy  INCREASE !!

THE GAS HAS THE MOSTT ENTROPY !!!

ROV [ Remotely Operated Vehicle ]

OCEAN EYE TEAM

Achievement :  won 2nd prize in Alexandria in IEEE project Fair ... and safety certificate From 

Mate ..

         -----------------------------------------------------------------------------------------

Remotely Operated Vehicle, is a tethered underwater robot used for many purposes across many industries

 that operate underwater. ROVs can perform many specialized tasks in industries such as oil and gas, 

commercial shipping, salvage, ship husbandry, potable water, ocean engineering, video production, scientific 

research and others.

The ROV will be designed to navigate under water easily through thrusters control with a feedback as a 

water proofed camera to able the pilot to gives his orders to the ROV.

The missions which the ROV should perform as a first phase:

There is an oil pipe line the Suez gulf which has an oil leakage, the fast and temporary response of the ROV 

until the specialized diver arrive to weld it; is to put four magnetic plugs on four holes and one scotch on the 

fifth hole, take three photos for the pipe line and release an air bag to indicate the leakage location.

Introducing the new SQUALO (ROV):
