Question

Answer fast please... ​

Answer 1

Answer:

1.EXAMPLE

SOLID :- iron, ice, wood,glass, rubber

LIQUID :- water,bromine, oil, milk, curd

GAS:- smell of perfume, dust, water vapour,

air, oxygen

2. when water is heatwd it is evaporated and when temperaturenis higher then 100 degree it starts vaporised and converts into water vapour

3.LPG :- liquified petrolium gas

CNG :- compressed natural gas

lpg in our homes with some mixing of other gases

cng used in cars

4. at 100 it is liquid

after 100 a very very small high temperature converts it into vapour

at 0 it is solid or liquid both

at 250 it is gas

hope it helps

kindly mark me as brainliest

follow me

when a liquid is heated it evaporates in gaseous state

LPG and CNG = LPG stands for 'Liquified Petrol Gas' and CNG for Compressed Natural Gas'.

USE = Compressed natural gas (CNG) (methane stored at high pressure) is a fuel that can be used in place of gasoline, diesel fuel and liquefied petroleum gas (LPG). CNG combustion produces fewer undesirable gases than the aforementioned fuels.

100 = When the temperature hits 100 degrees Celsius, the boiling point of water, the water will begin turning into a gaseous state called steam and will begin to float in the air as a cloud.

250 = The boiling point of water is 100°C. So the physical state of water at a temperature of 250 degree Celsius which is much above its boiling point will be gaseous state. The physical state of water at its boiling point temperature of 100 degree Celsius will be both liquid state as well as gaseous state

0 degrees is the melting point of water. ... Ice at 0 degrees C is at a lower energy state than liquid water at 0 degrees C. If you cool liquid water to exactly 0 degrees C, but immediately stop, the water is perfectly fine existing at 0 degrees C as a liquid.
