particle theory

Question 1

in which state of matter are the particles closest together?

Answer 1

solid

Question 2

Which states of matter increase in size when heated?

Answer 2

solid

Question 3

What type of energy do particles obtain when heated?

Answer 3

kinetic energy

Question 4

how does sugar dissolve in water using the particle theory

Answer 4

When sugar dissolves, the sugar particles separate and mix with the water particles. … As the sugar particles separate, the smaller water particles fit into the spaces between the larger sugar particles. The water and sugar particles are attracted to each other, so they move closer together when they are mixed.

Question 5

Why are sugars soluble in water?

Answer 5

Sugar dissolves in water because energy is given off when the slightly polar sucrose molecules form intermolecular bonds with the polar water molecules. The weak bonds that form between the solute and the solvent compensate for the energy needed to disrupt the structure of both the pure solute and the solvent.
