Please, could you correct my text? The simplest experimental lesson (Thank you in advance. ^__^ ) We can find water in three forms: solid (ice), liquid, or gas (vapor). Solid water—ice is frozen water. Water freezes at 0° Celsius, 32° Fahrenheit. Liquid water To make water change from one state to another we must change its temperature. To do that we need to heat it up or cool it down. Water as a gas When you boil water, the water changes from a liquid to a gas. Water boils at 100° Celsius. The professor asked the students "Who can tell me where the water went?" No one answered. The professor said: ”Where did the water go? They evaporated into the air and melted into the vast infinity of the blue sky." The professor said: "If a person's temperature for life is below 0 °C, then the person's living state will be ice, and his entire life realm will be as big as the place where his feet are standing; If a person has a normal attitude towards life, then he is a normal water, he can flow into the river, the sea, but he can never leave the earth; If a person is 100°C hot for life! Then he will become water vapor, become a cloud, he will fly, he not only has the earth but also has the sky, his world is as big as the universe. " The temperature of the water is increased by 100 °C by the fire, and the temperature of the human heart is heated by positive thinking, optimistic heart, caring of relatives and friends, gentle and considerate heart, curiosity about the world, hard work, etc. I hope that this article will let the temperature of your friends rise to 100 °C, which will make your life more colorful. I think it's great that the professor can bring thought-provoking ideas to a lesson. Thank you in advance. ^__^
