Substances whose particles have attraction to each other have lower melting points than substances whose particles have attraction to each other.

weak and strong.

Explanation:

Given that molecules have weak attraction for each other, the solid melts easily when exposed to heat. However, when there are strong intermolecular forces of attraction, it becomes more difficult for the solid to melt hence a higher boiling point.

weak and strong

Explanation: Substances in which weak attraction exist between the particles requires less energy to break the bonds between the particles thereby resulting in lower melting points, but substances in which strong attraction exist between the particles requires more energy to break the bonds between them, thus resulting in higher melting points.

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.

no, the red giant is the hottest with 2.00.000.000 degrees celsius. while the white dwarf only 25,000 degrees celsius.
