Answer:
At the melting point, some molecules overcome the forces of attraction. Energy gained after the the solid melts increases the average kinetic energy or the temperature. When liquid is freezing the energy flows out the the liquid. As the kinetic energy decreases, they move more slowly.

Answer:
It is important to collect all data first, or else your guesses could purely be the opposite of the right answer. If you make inferences of what might happen, your guesses may be purely fictional, and totally off-topic. During experiments, this step is important.
Answer:
Ozone layer depletion causes increased UV radiation levels at the Earth's surface, which is damaging to human health. Negative effects include increases in certain types of skin cancers, eye cataracts and immune deficiency disorders.
Answer : The molar solubility of 
is 
Explanation :
The solubility equilibrium reaction will be:
The expression for solubility constant for this reaction will be,
Let the molar solubility be, 'x'
Now put all the given values in this expression, we get:
Therefore, the molar solubility of is
