This document discusses the properties and states of matter. It defines matter as anything that has mass and volume, and defines the three common states as solid, liquid, and gas. It provides properties to differentiate the three states, such as solids having a definite shape and volume, liquids having no definite shape but a fixed volume, and gases having no definite shape or fixed volume. The document also discusses phase changes between the different states when heat is added or removed, such as melting, boiling, evaporation, condensation, and sublimation.

Characterization and the Kinetics of drying at the drying oven and with micro...Open Access Research Paper
The objective of this work is to contribute to valorization de Nephelium lappaceum by the characterization of kinetics of drying of seeds of Nephelium lappaceum. The seeds were dehydrated until a constant mass respectively in a drying oven and a microwawe oven. The temperatures and the powers of drying are respectively: 50, 60 and 70°C and 140, 280 and 420 W. The results show that the curves of drying of seeds of Nephelium lappaceum do not present a phase of constant kinetics. The coefficients of diffusion vary between 2.09.10-8 to 2.98. 10-8m-2/s in the interval of 50°C at 70°C and between 4.83×10-07 at 9.04×10-07 m-8/s for the powers going of 140 W with 420 W the relation between Arrhenius and a value of energy of activation of 16.49 kJ. mol-1 expressed the effect of the temperature on effective diffusivity.

UNDERSTANDING WHAT GREEN WASHING IS!.pdfJulietMogola
Many companies today use green washing to lure the public into thinking they are conserving the environment but in real sense they are doing more harm. There have been such several cases from very big companies here in Kenya and also globally. This ranges from various sectors from manufacturing and goes to consumer products. Educating people on greenwashing will enable people to make better choices based on their analysis and not on what they see on marketing sites.

Matter In Our Surroundings
1.
2. Anything which has mass and
volume is called matter.
The quantity of matter present in
an object is called its mass.
S.I. unit of mass is kg.
Space occupied by a
substance is called its volume.
3. i) Matter is made up of particles.
ii)The particles of matter are very tiny.
iii)The particles of matter have space between
them.
iii)The particles of matter are continuously
moving.
iv)The particles of matter attract each other.
4. Activity :- Take some water in a beaker and note its level. Dissolve
some salt or sugar in it with the help of a glass rod.The salt
dissolves in the water but the level of water does not change.This
is because the particles of water get into the space between the
particles of water.This shows that matter is made up of particles.
(I)Matter is made up particles :-
5. Activity :- Dissolve 2 – 3 crystals of potassium permanganate in
100ml of water in a beaker.Take 10ml of this solution and dissolve
in 100ml of water.Take 10ml of this solution and dissolve in 100ml
of water. Repeat this process 5 – 6 times.This shows that a few
crystals of potassium permanganate can colour a large volume of
water because there are millions of tiny particles in each crystal.
(II)The particles of matter are very tiny :-
6. Activity :-Take some water in a beaker and note its
level. Dissolve some salt or sugar in it with the help of a
glass rod.The salt dissolves in the water but the level of
water does not change.This is because the particles of
salt get into the space between the particles of water.
(III)The particles of matter have space between them :-
7. Activity :-Take some water in a beaker and put a drop of blue or
red ink slowly along the sides of the beaker. Leave it undisturbed
for a few hours.The ink spreads evenly throughout the water due
to the movement of the particles of water and ink.
The intermixing of two or more different types of matter on their
own is called diffusion.
(IV)Particles of matter are continuously moving :-
8. Activity :-Take an iron nail, a piece of chalk and a rubber band.Try
breaking them by hammering, cutting or stretching. It is more
easier to break the chalk, less easier to break the rubber band and
difficult to break the iron nail.This is because the particles in the
iron nail are held together with greater force than in the rubber
band or chalk.
(V)Particles of matter attract each other :-

18. When a liquid is heated, its particles begin to
move even faster.Then at a particular
temperature the liquid begins to boil and
changes into gas (vapour).
Boiling is a bulk phenomenon. When a liquid
boils the bulk of the liquid changes into
vapour.
The temperature at which a liquid starts
boiling is called its boiling point.The boiling
point of water is 1000C or 373K ( 273 + 100).
Latent heat of vaporisation :-
The amount of heat energy required to
change 1kg of a liquid into gas at atmospheric
pressure at its boiling point is called the
latent heat of vaporisation.
19. When a solid is heated, the particles
begin to vibrate with greater speed and
begin to move more freely.Then at a
particular temperature the solid melts
and changes into liquid.The process of
melting is also known as fusion.
The temperature at which a solid melts
is called its melting point.The melting
point of ice is 00C or 273 K.
Latent heat of fusion :-
The amount of heat energy required to
change 1kg of a solid into liquid at
atmospheric pressure at its melting
point is called the latent heat of fusion.
20.
21. The change of state of matter from liquid to gas is
called condensation.
22. The change of state directly from solid to gas or from gas to solid is
called sublimation.
E.g. :- If solid camphor or ammonium chloride is heated, it changes
into vapour. If the vapours are cooled it changes into solid.
23. The change of a liquid into vapour at any temperature
below its boiling point is called evaporation.
Evaporation is a surface phenomenon. Particles from
the surface gain enough energy to overcome the forces of
attraction and changes to vapour state.
24. Factors affecting evaporation :-
The rate of evaporation depends upon surface area,
temperature,
humidity and wind speed.
Increase in the surface area increases the rate of evaporation.
Increase in temperature increases the rate of evaporation.
Increase in humidity decreases the rate of evaporation.
Increase in wind speed increases the rate of evaporation.
25. Evaporation causes cooling :-
When a liquid evaporates, the particles of the liquid absorb heat
from the surroundings and evaporates. So the surroundings
become cold. Wearing cotton clothes in summer keeps us cool
because cotton absorbs sweat and when the sweat evaporates it
absorbs heat from our body making the body cool.
