this SIM (Strategic Intervention Material) include a short discussion about evaporation and vaporization it include enrichment and activity about the topic

1. Strategic
Intervention
Materials

4. -process by which liquid
changes to its vapours at a
temperature below its boiling
point
-takes place at all
temperature. The
temperature may change
during evaporation
-is a slow and silent process
-takes place only at the
surface of the liquid
-the rate of evaporation
depend upon the surface
area of the liquid and the
wind speed, humidity and
temperature
VAPORIZATION
- process by which liquid
changes to its vapours at
its boiling point
-takes only at a fixed
temperature called boiling
point of the liquid. The
temperature during
vaporization does not
change
-is a fast and violent
process
-takes place over the entire
mass of the liquid
-the rate of vaporization
does not depend upon the
surface area, wind speed,
humidity and temperature

understanding!

8. Put a check (/) if you think it describes Evaporation or
Vaporization
Evaporation Vaporization
1 Quick process
2 Occurs at any temperature
3 Slow process
4 Takes places within liquid
5 Bubbles are formed
6 Heat supplied by surrounding
7 No bubbles are seen
8 Occurs at fixed temperature
9 Heat supply energy source
10 Temperature remains constant
11 Slow process

18. Wind is the flow of gases on a large scale.
Humidity is the amount of water vapor in the air.
A temperature is a numerical measure of hot or cold.
Liquid is one of the four fundamental states of matter, and is the only state
with a definite volume but no fixed shape.
Gas is one of the four fundamental states of matter. A pure gas may be
made up of individual atoms, elemental molecules made from one type of
atom, or compound molecules made from a variety of atoms.
