Task 1. Read the text and give the title: Matter is defined as any substance which has mass (or weight)and occupies soace.This definition should be broad enough to cover all physical objects in the universe. Wood water. iron, and paper are some examples of matter.Energy is closely related to, but not to be confused with, matter. Energy does not have mass and it does not occupy space. Heat and light are examples of energy. The smallest particle of matter which can be recognized as an original substance was thought to be a unit called the atom. Recently scientists have found particles even smaller than atoms, but our theories are still based on the atom The atom consists of a nucleus and a cloud of electrons. It is generally agreed that the electrons are small particles of electricity. which are negative in nature. These particles orbit the nucleus in much the same fashion that planets orbit a sun.
