Variant 2 Task 1. Read the text and give the title: Matter is defined as any substance which has mass (or weight) and occupies space. 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 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. Task 2. Answer the questions; use the information from the text: 1) Give the definition of matter. 2) Is energy related to matter? What is the difference between matter and energy? 3) What is the smallest particle of matter? 4) What parts does an atom consist of? 5) Are the electrons negative or positive in nature?

Задача 1. Прочитайте текст и дайте название:<br />Материал определяется как любая субстанция, имеющая массу (или вес) и занимающая пространство. Эта определение должно быть достаточно широким, чтобы охватить все физические объекты во вселенной. Древесина, вода, железо и бумага - это некоторые примеры материи. Энергия тесно связана с материей, но не должна быть спутана с ней. Энергия не имеет массы, и она не занимает пространство. Тепло и свет - это примеры энергии. Наименьшей частицей материи, которая может быть признана как оригинальная субстанция, считалось единица, называемая атомом. Недавно ученые обнаружили частицы, которые меньше атомов, но наши теории по-прежнему основаны на атоме. Атом состоит из ядра и облака электронов. Обычно считается, что электроны - это маленькие частицы электричества, которые отрицательны по своей природе. Эти частицы орбитируют вокруг ядра примерно так же, как планеты орбитируют вокруг солнца.<br /><br />Задача 2. Ответьте на вопросы; используйте информацию из текста:<br />1) Дайте определение материи.<br />2) Существует ли связь между энергией и материей? Что отличает материю от энергии?<br />3) Какая наименьшая частица материи?<br />4) Из каких частей состоит атом?<br />5) Электроны положительные или отрицательные по своей природе?<br /><br />Ответы:<br />1) Материал определяется как любая субстанция, имеющая массу (или вес) и занимающая пространство.<br />2) Да, энергия связана с материей, но не должна быть спутана с ней. Энергия не имеет массы и не занимает пространство, в то время как материю отличают наличие массы и занимаемого пространства. Примеры энергии - тепло и свет, а примеры материи - древесина, вода, железо и бумага.<br />3) Наименьшей частицей материи, которая может быть признана как оригинальная субстанция, считалось единица, называемая атомом.<br />4) Атом состоит из ядра и облака электронов.<br />5) Электроны отрицательны по своей природе.
