I. Read the text. Choose the most suitable heading from the list (a-g) for each part (1-5) of the text. There are two extra headings which you do not need to use.

A. Different Types of Matter.

B. Definition of a Glass.

C. States of Nuclei.

D. The Usage of Devices.

E. Unstable Matter.

F. What is Matter?

G. Matter Characteristics.

II. Read the text. For statements (6-15) choose “True” if the statement is true according to the text, “False” if the statement is false:

  1. Bulk matter consists of molecules at rest.

  2. Matter has liquid, solid and gaseous forms.

  3. A glass is a liquid with high viscosity.

  4. Both solid bodies and glass remain disorganized at their normal freezing points.

  5. In plasma some atoms penetrate into its positive nuclei and electrons.

  6. The accuracy of matter analysis relies on the instruments that are used.

  7. Bulk matter is characterized by its optical phenomena, the measurement of its mass and weight.

  8. Energy absorption and emission aren’t linked with energy levels of molecules.

  9. Dissociation and ionization depend on the excitation of energy levels of atoms.

  10. Atomic nuclei exist in different states.

III. Read the text. For questions (16-20) choose the correct answer (a, b, c or d).

16) Matter in bulk …

a) is considered to be solid.

b) has been studied for a long time.

c) exists in four forms.

d) exists in tree forms.

17) A glass is …

a) a liquid.

b) a solid.

c) the region of high density.

d) dependable on gas.

18) To analyze and understand matter …

a) some devices are used.

b) many calculations have been made.

c) we need a microscope.

d) the emission must be seen.

19) Matter can be characterized …

a) only by measurements of its mass and weight.

b) only by visible and invisible light.

c) by scientists.

d) both by measurements and optical phenomena.

20) Atomic nuclei can …

a) be analyzed.

b) can be said to be at rest.

c) exist only under certain conditions.

d) exist different states.
