Why liquid defuse fast then gas |
|
Answer» Sir comment box aap bhi padh lijiye.....Maine apna point baad me clear bhi Kara hai... Yes it\'s right It\'s that gases defuse faster than liquid ...... Same goes for the answer given Mam liquid ka puccha h question thik se pidhye Because it\'s molecules are more losely packed or we can say there is least force of attraction between their molecules and thus they have more kinetic energy as compared to liquids ....... Which helps them to get defused rapidly in comparison to liquids |

Which metal is kept in kerosene |
|
Answer» As meytal such as potassium are so highly reactive that on coming in contact with air, immediately it catches Fire, hence they are kept under kerosene. Sodium is a very reactive metal.
