chemistry studies the properties of matter and energy and how they interact with each other. in fact physics is also defined in the same way. chemistry and physics are an integral part of physical science. chemistry specifically studies the properties of the substances and their interactions with different types of matter, especially when they involve electrons.
chemistry is all around you if you notice. chemical reactions are taking place within our body, and outside in our natural environment all the time. however, we may not know about it unless we study or read about them, and then understand them. most of the chemical reactions are not visible to our naked eye.
chemistry is basically the study of everyday chemicals that are very much present around us and available, and that which can be applied in real life. these chemicals can be applied in many ways like in the kitchen. the kitchen is the ideal lab where people can experience various chemical reactions and even study them. they need not do anything special. they can simply do what they do in the kitchen everyday and still observe the chemical reactions that occur.
a simple task like boiling of water is a chemical reaction. we all know that water boils at 100 degrees centigrade. when we boil water everyday, we can observe this.
tamarind is a simple ingredient used in cooking in several dishes. it gives that extra tangy taste that you are looking for. however, when you cook or store tamarind in aluminum container, it releases certain types of chemicals into foods. when you learn about this, you would avoid cooking tamarind based substances in aluminum vessels, or storing tamarind in an aluminum container. a saturation point is when the water cannot dissolve anymore sugar or salt. this is why food ends up tasting very salty or sweet as it can take in no sugar or salt.
checking the temperature when we feel feverish using a thermometer is a simple chemical process we do sometimes. the mercury in the thermometer rises if the body temperature is high. when we touch certain chemicals like chlorine we can burn the skin. this is because of the chemical properties of these chemicals that are causing this burning sensation.
chemistry comes in use for killing pests and rodents at home. when we use naphthalene balls at home we are using a product of chemistry. many of us use pickling as a method to preserve vegetables. pickling is a simple chemical process that involves the process of osmosis.
There are not many theatres in my town, but they are all very popular with the public. I am a theatre lover, too. As for me, I prefer drama to all other theatres, but I also like opera and musical comedy.
I’ll never forget my first visit to the Opera and Ballet Theatre. My friend and I wanted to see the famous ballet “Swan Lake” by Tchaikovskyi. We bought the tickets in advance and came to the theatre half an hour before the show. At 7 sharp the performance began. From the very first minute I was deeply impressed by everything I saw on the stage. The costumes were fine. The dancing and music were thrilling. The ballet seemed to me a fairy-tale. I had never seen anything more wonderful. My friend also enjoyed every minute of it. When the curtain fell at the end of the performance, there came a storm of applause. It seemed that it would never end. The dancers received call after call. They were presented with large bouquets of flowers. We also applauded enthusiastically. The performance was a great success.

В моем городе не так много театров, но все они очень популярны среди населения. Я тоже любитель театра. Что касается меня, я предпочитаю драматический всем другим театрам, но я также люблю оперу и музыкальную комедию.
Я никогда не забуду мой первый визит в Театр оперы и балета. Мой друг и я хотели посмотреть знаменитый балет Чайковского "Лебединое озеро". Мы купили билеты заранее, и пришли в театр за полчаса до шоу. Ровно в 7 началось представление. С первой же минуты я был глубоко впечатлен всем, что видел на сцене. Костюмы были хороши. Танцы и музыка были захватывающими. Балет показался мне сказкой. Я никогда не видел ничего прекраснее. Мой друг и я наслаждались каждой минутой. Когда занавес опустился в конце спектакля, раздался взрыв аплодисментов. Казалось, что этому не будет конца. Танцоров вызывали снова и снова. Им подарили большие букеты цветов. Мы также аплодировали с энтузиазмом. Спектакль имел большой успех.
