Hard water

HYPOTHESIS: As the ice cubes melt in the warm water, the melted water from the ice should flow towards the bottom of the cup because the melted colder water is denser than the surrounding water. PURPOSE: The purpose of this experiment is to improve my ability to observe an experiment. In addition, it will help aid me in making proper observations while also drawing conclusions. RAW MATERIALS: Clover Valley food color and egg dye blue food coloring contains FD&C Blue #1…

What is the effect of the properties of a mixture on the methods of separation and the mass of each substance that is obtained after separation? Background Research: What is a mixture: The reason for the chosen methods: Water is able to dissolve salt because the water molecules (H2O) attracts the sodium(Na) and chloride(Cl-) ions. Hypothesis: If we use a magnet to separate the iron from the mixture we will only extract the iron from the mixture because nothing else in the mixture is…

cornerstones of human cleanliness. Soap is, “a substance used with water for washing and cleaning, made of a compound of natural oils or fats with sodium hydroxide or another strong alkali, and typically having perfume and coloring added”( Soap 2018 ). Detergent is, “ a water-soluble cleansing agent that combines with impurities and dirt to make them more soluble and differs from soap in not forming a scum with the salts in hard water” ( Detergent 2018 ). Both soap and detergent are both…

protect the environment? This essay will discuss 3 aspects of environmental pollution: causes, effects, and solutions. There are many types of environmental pollution such as: air pollution, water pollution, noise pollution,…… We live on earth, which is known to have an environment, where air and water are 2 basics things in our life.

The crisp ripples of the water left my skin as I began to grow out of the water. The sun beat down on my eyes as a squinted trying to see. This last couple week of August I was spending time in South Carolina at my grandparent's house. We went there every year to see them and spend time with them on their lake. It was our first day out of trying to water ski with my sisters and my grandparents. We loaded everything up in the speedboat as we jumped off the dock and headed out onto the lake. I…

walk a few hundred feet to the shore. When we got to the beach my brother tried first. We looked up on Youtube how to ride a skim board on the day before. It showed that you start striding in the water near the shore where it is only a few inches deep. Then you reach down and slide the board on the water, and then you jump on and revel in the ride. My brother did not do this. He threw the board down and jumped on, and he completely blundered and fell straight on his back. Next was my turn. I…

Water is a necessity for life, and with Rome’s geography, it was hard to get it to the dispersed cities. Rome was close to the ocean, but had no way to efficiently get water to everyone in their compact cities. This is where the Aqueducts came into play, the Aqueduct was a system of intake filters and underground tunnels that deliver water to the Roman cities. The Aqueduct supplied water to the markets and to many homes all around the city. Without this the Roman Empire would not have…

Water was moving down on the edge of the bath. Steam was surrounding the girl sitting in the water, hiding her from the real world that was behind the window, and letting her dream. Water splash - and her thin legs merged to each other, transforming into azure, scaly mermaid tale. The steam became thicker, and then purple whales and giant pink elephant flew above her head. The noise around transformed into the songs of sirens that lured her to join the dream, leaving any troubles behind. Knock…

onto dry land. Giant waves created by earthquakes will consequently overflow the land with water. Another rare case of flooding is dam failure. Cold fronts can bring heavy rainfall to Australia, particularly in winter and spring and can consequently cause flooding. There are many types of floods which include…

than the freezing point of water, then it will be a form of water or ice melting into water. The different molecules, or also called the things that make up the ice or water, are more dense in cold water. They become dense and come to each other which makes them tight into an ice cube. When the ice gets warm, it moves the molecules apart to make it back into water. When as water, the molecules move faster than as to be ice. That's what makes ice melt and transform into water. If anyone has…
