welcome to LMES             

How to avoid car accident using potatoes ? lets start this session. while we drive the car if the rain comes suddenly fog will create in the front glass of car . It is hard to clean the fog in the glass so that accidents will take place . To avoid this we want one small potato and science .   

First how this fog forms we can see . Take a glass or cup , fill it with ice water , you can see the fog formed outside . Why this happens ? when we boil water at 100 degree Celsius evaporation takes place in the same way if you keep a plate in the passage of evaporation condensation takes place . when we pour the ice water in the tumbler the temperature of the tumbler cools down . when the atmospheric water vapour touches the glass it will condense and form as fog . In the same way the fog will forms in car . The outside of the car changes has low temperature so the fog forms . 

TO AVOID THIS
