Why polythenes are considered to be the major threat to our environment? class - VI OUR ENVIRONMENT |
|
Answer» n Why POLYTHENES are considered to be the major threat to our environment? ANSWER :The polythenes are considered to be the major threat to our environment because -The polythenes do not decompose, as they are non BIODEGRADABLE wastes.They used to BLOCK the drains.When we burn them, air pollution is caused.And if animals eat it, their intestine may block and the animals may die.So,We should avoid the use of polythenes.Instead of them we can use paper bags, cloth bags or jute bags.Recycle them, instead of burning. |

Which of the following is incompressable____ solidsliguids gasesall are incompressable |
|
Answer» - ______________________________Defination-SolidA state of matter where the molecules are closely Packed to each other.EXAMPLE: Ice______________________________Defination-LiquidA state of matter where the molecules are not so TIGHTLY or loosely packed. EXAMPLE: Water ______________________________Defination-Gaseous stateThe state of matter where the molecules are very loosely packed. EXAMPLE: Water vapours===================================SolidSolids are incompressible.______________________________Explaination: Why the answer isn't GASES??=> Gases are highly compressible, as the molecules are loosely packed and scattered all around COMPARED to SOLID and liquid. => The distance between molecules decrease with the increase in pressure.______________________________Why the answer isn't Liquid??=> Liquids need a LOT of pressure to be compressed, they have very less space between their molecules. => As read above the distance between molecules decrease with the increase of pressure. => As liquids have less molecular space,it's considered to be hard for liquids to compress .______________________________Why the answer is Solid??=> Solids are the ones having no space between molecules. Liquids are considered to have more molecular space compared to solids. => Therefore they can't be compressible.______________________________Hence, the answer is Solids______________________________ |
