Which of these processes involve the weakening of the attraction between particles 1} freezing 2}condensation 3}evaporation 4}crystalization

Answer : The correct option is (3) Evaporation.

Explanation :

Evaporation : It is a process in which the liquid particles are converted to gaseous particles. The inter-molecular forces of attraction between the liquid particles will be weakened. As a result the phase change occurs.

Freezing  : It is a process in which a phase changes from liquid state to solid state.

Condensation : It is a process in which a phase changes from gaseous state to liquid state.

Crystallization : It is a process in which a solute particles get separated from the solvent in the form of crystals ( in solid phase).

Whereas in freezing, condensation and crystallization we are moving from one phase having weaker inter-molecular forces of attraction to another phase having stronger inter-molecular forces of attraction. So, in these processes strengthening of attraction between the particles takes place.

Hence, the correct answer is Evaporation.

answer: the figure is attached herewith.

step-by-step explanation:   we are given to sketch a unit circle and label the terminal points corresponding to

in the attached figure, we have drawn a unit circle, with centre at o(0,0) and radius 1 unit. we have labelled the points a, b, c, d and e corresponding to the angles below

∠aox = 60°,

∠box = 120°,

∠cox = 180°,

∠dox = 240°,

∠eox = 300°.

and the coordinates are a(0.5,1), b(-0.5,1), c(-1,0), d(-0.5,-1) and e(0.5,-1).

thus, the answer is complete.

the answer is either b or c
