When water absorbs enough
heat, it becomes a gas (water
vapor). This process is called
evaporation.Answer:

Water is the only
substance that exists on
Earth in each of its
three states and easily
changes from one state to
another. Water sometimes
changes its location by
changing state in a
continuous pattern called
the water cycle or the
hydrologic cycle. The
water cycle is selfrenewing and continuous. The Sun provides the energy to power the water
cycle.
When water changes state in the water cycle, the total number of water
particles remains the same. The changes of state include melting,
sublimation, evaporation, freezing, condensation, and deposition. All
changes of state involve the transfer of energy. The water particles in each
state behave as energy is absorbed or released. . Condensation, deposition,
and freezing are processes that occur as a result of a decrease in the heat
energy of water particles.
When solid ice gains heat, it changes state
from solid ice to liquid water in a process
called melting. Ice cubes in a cold drink,
for example, gradually melt. Each spring
you see snow melt into slush and puddles.
Sometimes adding heat energy to solid ice
causes a change of state from a solid to a
gas. This change, directly from a solid to a
gas without becoming a liquid, is called
sublimation. On crisp, dry winter days you
might notice that snow banks shrink, or ice
gradually disappears, without first becoming slushy and wet.
Water vapor
(steam) mixes with the air and
seems to disappear. A simple
example is water boiling in a
teapot and escaping into the
air. Another type of
evaporation occurs from the
surface of plant leaves as the
plant’s temperature increases
and water vapor is released
into the air as the plant
“breathes” in the process of
transpiration.
When water vapor loses thermal energy and becomes liquid
water, condensation has occurred. Rain and dew are examples
of condensation. A cold can of pop placed outside on a hot
summer day often accumulates water droplets. This is
because water vapor in the air condenses when the cold can
cools it.
Sometimes, removing heat energy from
water vapor causes it to become a solid,
rather than a liquid. Deposition occurs when
water vapor changes state directly from a
gas to a solid. Deposition is the reverse of
sublimation. One example of deposition
occurs high in the atmosphere or on the top
of high mountains where the temperature is
very low. In these conditions, water vapor
forms snow without becoming a liquid first.
Solid water includes permanent ice and snow in
glaciers and polar regions, and ice and snow
that form in the winter. Liquid water falls to
the ground in the form of rain. Liquid water
also forms when winter ice and snow begin to
melt. Much of this water is called runoff.
Answer:
Evaporation= The changing of water into water vapour is called evaporation.
Transpiration= The loss of water from plants as water through the pores of their leaves is called transpiration.
Condensation= The changing of water vapour into liquid water on cooling is called condensation.
