Water Cycle:
The water cycle shows the continuous movement of water within the Earth and atmosphere.
Which
of the following process/es is/are involved in water cycle?
a) sublimation
b)
evaporation
c) condensation
d) both b and b
Which of the following is the source of heat for evaporation during water cycle?
a) geothermal heat
b) sun
c) natural gas
d) none of these
Which of the following is directly converted into gaseous phase from solid phase?
a) ice
b) dry ice
c) iron
d) NaCl
Explanation:Dry ice is the solid form of carbon dioxide. It is commonly used for temporary refrigeration as CO₂ does not have a liquid state at normal atmospheric pressure and sublimates directly from the solid state to the gas state.
When
dry ice absorbs heat from its surrounding, it directly converts in gaseous state
without changing into liquid phase. What is this process?
a) sublimation
b) evaporation
c) melting
d) condensation
Exercise:
B and c
