STATE OF WATER=WATER HAS THREE STATES(1)SOLID(ICE)
(2)LIQUID(WATER)(3)GAS(WATER VAPOUR)
←-----------------------------------------------------------------------------------------------------
-----→
EVAPORATION=THE PROCESS OF CONVERSION OF WATER VAPOUR STATE
IS CALLED EVAPORATION DRYING OF WET CLOTHES,MOPPED FLOOR,AND
SWEET ON OUR BODY ARE SOME EXAMPLES
←-----------------------------------------------------------------------------------------------------
-----→
CONDENSATION=THE PROCESS OF CONVERSION OF WATER VAPOUR INTO
ITS STATE IS CALLED CONSENSATION EXAMPLES=THE APPEARANCE OF
WATER DROPLET ON THE OUTER SERFACE OF THE GLASS LUMBER WHEN
COLD WATER IS FILLED IN THE GLASS
[2] RAIN AND CLEW ARE NATURAL EXAMPLES OF CONDENSATION

HUMIDITY=HUMIDITY REFERS TO THE AMOUNT OF WATER VAPOUR
PRESENT IN THE AIR THE DAILYHUMIDITY LEVEL IN YOUR AREA ARE
MESURED AND REFORTED BY NEWPAPER AND OTHER SOURCES

ATMOSPHERIC WATER GENRATER=AN ATMOSPHERE WATER
GENRATOR(AWG) MACHINE IS A DEVICE THAT PRODUCE DRINKING WATER
BY COLLECTING MOISTURE FROM HUMID AIR

HOW DOES IT WORK=THE AWG MACHINE WORK BY COOLING THE AIR
WHICH CAUSES THE WATER VAPOUR IN THE PROCERC IS SIMILAR TO THE
