Today i am going to talk about the wonders of boiling liquids. Boiling is used in many ways. Boiling is most commonly used in heating food like macaroni but there are many other uses. If someone is stranded in amn isolated location, they need to boil any water they find because the germs, parasites, slat, etc can make you sick and even kill you on occasion. Heat kills the germs and anything in the water or liquid. Drinking unsoiled water in the water is just as dangerous as eating raw meat which you need to cook. Boiling a substance does not always require great heat, some objects can boil at a much cooler temperature because the pressure is different around the substance. Boiling something will make it become a gas. Letting a substance evaporate takes a lot longer than boiling. Ocean water is not drinkable because of the parasites and salt but when you boil it, all the parasites.will die off that are in the water as well as the salt allowing you to drink. If one did not purify the water and they could get sick. Boiling your food is a very easy task but we don't notice how helpful and easy it is to use. Preparing food would be a lot harder if boiling did not happen within the household. Think about this, you could not eat macaroni and cheese if you couldn't boil. Boiling is a life saver in some situations or an easy cooking method but without it a lot of things would be harder.
