MODEL WRITE-UP OF THE WORKING MODEL / PROJECT
PRINCIPLE AND WORKING
My exhibit / project ‘CHEMO COOLING FRIDGE’ is based on “ENDOTHERMIC PROCESS”.
The term endothermic process describes a process or reaction in which the system absorbs energy from its surroundings; usually, but not always, in the form of heat. The term was coined by Marcellin Berthelot from the Greek roots endo-, derived from the word “endon” meaning “within” and the root “therm” –meaning “hot”. The intended sense is that of a reaction that depends on absorbing heat if it is to proceed.
Examples: Photosynthesis, sublimation of carbon dioxide, dissolving of ammonium chloride, dissolving of urea, melting of ice, etc.
For my exhibit / project I had chosen ‘dissolving of urea’.

~ Take one large metal box and it should be covered with cotton box from outside.
~ The covered cotton box works like an insulator.
~ A small hole should be made at the bottom of the large metal box.
~ A tube is adjusted in that hole which connects into a tray.
~ Keep a small metal box in the large metal box. And it is used for storage of vegetables.
~ The urea should be poured in between the gap of the boxes.
~ Slowly we should sprinkle the water on urea.
~ Then the urea dissolves in water which is an endothermic process.
~ The temperature of small metal box and vegetables decreases to 10ºC to 15ºC. So, vegetables can be stored for 2 to 3 days more.
~ The dissolved urea solution can be dehydrated under sun light in the tray. So, we can get urea crystals which can be re-used.
