the freezing point or melting point of water is the temperature at which water changes phase from a liquid to a solid or vice versa. The freezing point describes the liquid to solid transition while the melting point is the temperature at which water goes from a solid (ice) to liquid water. In theory‚ the two temperatures would be the same‚ but liquids can be super cooled beyond their freezing points so that they don’t solidify until well below freezing point. Ordinarily the freezing point of water

confirmed there was liquid flowing water on Mars on the 28th of September. The water was found running down slopes in the warmer months when the temperatures were above -10℉. The water was similar to our ocean water in the way that it was salty but the salt found in the water was more like what we use to de ice the roads. There are long‚ dark streaks that show where the water flows because as of right now there are no streams‚ rivers‚ or lakes on Mars so the water comes from under the soil and wets

Salt Case Study Salt and Food We all need a little salt because it helps keep your body fluids at the right concentration. However‚ the majority of us eat more salt than we need. On average‚ people in the UK eat about 8.1g of salt a day. Even though it doesn’t sound like a lot‚ to reduce the risk of disease‚ adults should not be eating more than 6g of salt per day. A main source of salt is table salt. Your body only needs 1/4 teaspoon of salt every day. Salt is naturally found in foods but

Each year‚ on average‚ there are 105 snowstorms. Salt is driven around in millions of trucks across the country to help deice the roads to make way for safe travels. In the United States‚ 20 billion pounds of salt are used every year to treat the icy roads after snowstorms. Common salt‚ the salt almost every American has on their dinner table‚ NaCl is most frequently used to deice roads across the country. Salt is very cost effective and efficient when used properly‚ however it is causing more harm

known as common salt. It is important because it is essential to the health of human beings and of animals. for domestic use it is fined down to what is known as table-salt‚ and small quantities of other chemicals are added to it to keep it free-flowing when in contact with the atmosphere. Salt and potassium are combined to produce iodised salt‚ used when iodine is lacking in diet. It’s absence cause goitre‚ the swelling of the thyroid gland.

Abstract The experiment allowed students to explore different electrolytes and classify them into acids‚ bases and salts by using different indicators or by measuring the pH levels of each. The experiment also helped students classify different substances through their conductivity properties. The preparation of a 1 M stock solution from NaOH pellets diluted to a

1.Explain how human interference in the water cycle can affect water availability The water cycle is the process of evaporation‚ condensation and precipitation of water on Earth including rain water and how it is distributed. Human factors such as forest clearing‚ urban construction and changes in land use can all affect the distribution of water. Infiltration can be affected by forest clearance. This also affects percolation and the water table. When there is rain the forests holds a lot of rainfall

Dissociation: Dissociation in chemistry and biochemistry is a general process in which ionic compounds (complexes‚ or salts) separate or split into smaller particles‚ ions‚ or radicals‚ usually in a reversible manner. Strength of Acids: The strength of an acid refers to its ability or tendency to lose a proton. There are very few strong acids. A strong acid is one that completely ionizes in water. In contrast a weak acid only partially dissociates. Examples of strong acids are hydrochloric acid (HCl)‚ hydroiodic

lived a salt merchant. He had a monkey for his assistance. Every morning‚ he would load a sack of salt on the donkey and go to the nearby town to sell it. On the way‚ they had to walk across a pond. One day‚ while crossing the pond‚ the donkey thought‚”Ooh! This load is so heavy that I become exhausted very soon. I wish I could get some of this load taken off my back.” Just then the donkey tripped and fell into the water. Fortunately‚ the donkey was not hurt. But the sack of salt on the donkey’s

The Effects Sodium Chloride has on pond water Introduction Ponds are depressions in the ground that fill with water from either run offs or melting snow or rain fall from many different weather changes. There are two types of ponds permanent and temporary. Ponds tend to be much smaller in size and are usually only six to ten feet in depth. This differs from a lake because the size of a lake is much larger and is much deeper. The temperature of a pond is usually the same from top to bottom and
