matter is made up of particles
Matter is continuous in nature
particles of matter are always in state of motion
particles of matter attract each other
during summer, water kept in a Earthen pot becomes cool because of
Diffusion
Transpiration
osmosis
evaporation
on converting 25 degree centigrade 38 degree centigrade and 66 degree centigrade to kelvin scale the correct sequence of temperature will be
298K,311K,339K
298K,300K,338K
273K,278K,543K
298K,310K,338K
Choose the correct statement of the following
Conversion of solid into vapours without passing through the liquid state is called a vapourisation
conversion of vapour into solid without passing through the liquid state is called deposition
conversion of vapour into solid without passing through the liquid state is called freezing
conversion of solid into liquid is called sublimation
the property to flow is unique to fluid, which of the following statement is correct
only gases behave like liquids
gases and solids behaved like fluids
gases and liquids behaves like fluids
only liquids are fluids
the boiling point of diethyl ether and Acetone and normal butyl alcohol are 35 degree 56 degree 118 degree respectively, which of the following correctly represent their boiling points in K
306k,329k,391k
308k,329k,392k
308k,329k,391k
329k,392k,308k
which condition out of the following will increase the evaporation of water
increase in temperature of water
decrease in temperature of water
less exposed surface area of water
adding common salt to water
in which of the following conditions the distance between the molecules of hydrogen gas would increase
(i) increasing pressure on hydrogen contained in a closed container
(ii)some hydrogen gas leaking out of the container
(iii)increasing the volume of the container of hydrogen gas
(iv)adding more hydrogen gas to the container without increasing the volume of the container
i & iii
i & iv
ii & iii
ii & iv
which of the following sets of phenomena would increase on raising the temperature
evaporation, diffusion, compression of gases
evaporation, compression of gases,solubility
evaporation, diffusion, expansion of gases
evaporation, compression of gases,solubility,diffusion
which of the following is not a property of solids?
interparticle space are minimum
definite shape and volume
Forces of attraction between the particles are maximum
particles can move freely within a limited space
Seema visited a natural gas compression unit and found that the gas can be liquefied under specific conditions of temperature and pressure while sharing her experience with friend she got confused help her to identify the correct set of conditions
low temp low-pressure
high temp low-pressure
low temp high pressure
high temp high pressure
melting points of four solids a b c d and e are 388K,54K,290K,and 600K, the interparticle forces of attraction are in the order
a<b<c<d
b<c<a<d
c<b<a<d
b<d<c<a
as the solid melts to form liquid
compressibility increases
inter particle forces of attraction decreases
the kinetic energy of the particle increases
all of these
liquid diffuse slowly slowly compared to gases
because
the molecule of liquids are heavy
the molecule of liquids move fast
liquids do not have any definite shape
in liquid state, the molecules are held together by strong intermolecular forces
which of the following does not affect the rate of evaporation
wind speed
temperature
HUMIDITY
insoluble impurities
a few substances are arranged in the increasing order of interparticle spaces. which of the following represents a correct arrangement
gold,ethanol,nitrogen
water.iron,oxygen
aliminium,hydrogen,glycerine
carbon dioxide,methanol,copper
which of the following does not undergo sublimation
ammonium chloride
sodium chloride
solid carbon dioxide
iodine
on kelvin scale 0 degree centigrade is equal to
273K
-273K
0K
100K
solids do not flow because
of large molecular space between particles
they do not have definite shape
they have very strong intermolecular forces in between particle
all of these
correct condition to liquify a gas into liquid is
low temperature low pressure
low temperature high pressure
high temperature low pressure
high temperature high pressure
