The table shows the range of the amount of energy required to break the bonds between the molecules of a substance in the solid, liquid, and gaseous states. Bond-Breaking Energy
State Energy
P 3 units
Q 0.01 unit
R 0.1 unit

Which of the following is the correct order of the relative strengths of the intermolecular forces in the three states?
A. P > R > Q (I think its this one, but i'm not too sure)
B. Q > R > P
C. R > Q > P
D. P > Q > R

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.
