3. Molecules in the solid phase have the greatest amount of energy,
while gas particles have the least amount of energy.
4. The average amount of empty space between molecules gets
progressively smaller as a sample of
matter moves from the solid
to the liquid and gas phases.
5. If the molecules are heated further, the liquid water will become in its
solid phase (ice).
6. Diffusion is the movement of particles from a high concentration to a
low concentration
B. Work with language
I. Match each word in A with its synonym in B.
A. at random, to lack, to clarify, similarity, evidently, to conceive the
idea, emergence, to presume, to verify, to conjecture
B. to confirm, to suppose, to guess, not to have, obviously, without
reason or aim, to make clear, to form in the mind, likeness, appearance
II. Put all possible questions to the following sentences.
1) The kinetic molecular theory of matter states that all particles have
energy.
2) Molecules in the solid phase have the least amount of energy.
3) There are spaces between particles of matter.
4) The kinetic theory of matter is also illustrated by the process of
diffusion.
5) There are attractive forces between atoms.
6) The energy of the molecules increases, if the ice is heated.
7) The color slowly spreads out through the water.
III. Put the words into the right order. Check your answers with the text.
