MATTER IN OUR 
SURRUNDINGS
MATTER 
 Matter is anything that occupies space 
and has volume . In other words , they 
have only mass and volume . 
For eg.. The pen with which we write , 
notebooks etc are all made up of matter .
Matter can be classified into 3 
states :
In Solids, The particles are packed closely 
together. The forces between particles are strong 
enough so that the particles cannot move freely . 
As a result, a solid has a stable, definite shape, 
and a definite volume. 
A liquid is a nearly incompressible fluid that takes 
the shape of its container but has a fixed volume. 
Intermolecular space is more in liquids than in 
solids. 
A gas is a compressible fluid. A gas takes the 
shape of its container andit will also fill the 
container . In a gas, intermolecular space is 
much greater than solids and liquids
MELTING POINT & BOILING POINT 
 Melting Point 
The temp. at which a solid melts to 
become a liquid at the atmospheric 
pressure is called its melting point. 
The melting point of ice is 273.16 k . 
The state of melting is also known as 
“ fusion “ 
 Boiling Point 
The temp. at which a liquid boils to 
became a gas at the atmospheric 
pressure is called its boiling point.
Latent heat of vaporisation is the 
heat energy required to change 1 
kg of a liquid to gas at atmospheric 
pressure at its boiling point. 
 Latent heat of fusion is the 
amount of heat energy required to 
change 1 kg of solid into liquid at its 
melting point.
Evaporation 
 The phenomenon of change of a liquid 
into vapours at any temp. below its boiling 
point is called evaporation
Factors affecting evaporation: 
1.Surface area : 
if the surface area is increased , the rate of 
evaporation will also increase ,,, for eg . 
While putting clothes for drying up we 
spread them out
2 . Temperature : 
With the increase in temperature , the rate of 
evaporation also increases 
3 . Humidity : 
Humidity is the amount of water vapour present 
in in air … if the amount of vapour in air 
increases , the rate of evaporation decreases. 
For eg , a dessert cooler cools better on a dry 
day as compared to a humod day
EVAPORATION CAUSES 
COOLING 
 Evaporation is the conversion of water to vapour at a temperature 
below boiling point. 
Water has a 'Vapour Pressure' at any temperature below 100°C at 
atmospheric pressure. (At the boiling point, water is NOT 
evaporating, it's Vaporising. Evaporation takes place below the 
boiling temperature). 
The molecules leaving the water as vapour are moved away by any 
movement of air above the water and therefore cannot return to the 
water. The Energy required to evaporate the water is called 'Latent 
Heat' and takes place by removing the necessary heat from the 
water as 'Sensible Heat' thereby decreasing the water temperature.
