Blank 1 Blankity Blank Blankity Blank Mr. Blank 4/9/02 Effects of Salts on the Freezing Point of Water In this experiment‚ you will study the effect that several solutes have on the Freezing Point of water. When a solute is dissolved in a liquid‚ the temperature at which that liquid freezes decreases‚ because the molecules of the solute become attached to the water molecules‚ making it more difficult for the water to form its crystaline shape and form into ice. This process is called Freezing

Marisela Andrade The Effects of Salt Water on Gummy Bears Facilitated diffusion depends on passive transport. Molecules cross cell membrane by diffusion. A type of diffusion is osmosis. If no energy is input into the system during diffusion‚ the molecules will reach a state of equilibrium. The purpose of this experiment was to study why the death occurred among those who drank salt water. Two blue gummy bears had a height of 2 centimeters each. The mass of these gummy bears together were

Salt and the effect it has on water. Do you like salt? Do you put it on your food to make it taste better? Salt doesn’t just make food taste better; it can change the freezing and boiling point of water. I bet you didn’t know that! There’s a reason for that‚ but I’ll explain that a little later. First‚ let’s find out if salt can actually change the freezing and boiling point of water. To do so‚ we need to do an experiment. Now‚ if you’re going to do an experiment‚ you’re going to need a hypothesis

HOW does saLT AFFECT THE BOILING POINT OF WATER? 1 How Does Salt Affect the Boiling Point of Water? Elizabeth Mompoint Everglades High School HOW does saLT AFFECT THE BOILING POINT OF WATER? 2 Abstract The purpose of this experiment was to determine whether or not salt would affect the boiling point of water. Much of the research I conducted rejected my hypothesis which stated: if I add salt to water‚ then the boiling point of

The aim of this experiment was to investigate the effects of salt type and concentrations on the rate of heating and the boiling point. Then from this data make a conclusion which salt type and concentration is the most energy efficient at heating water to its boiling point. It was hypothesised that highest concentration of MgCl2 was going to be the most energy efficient at heating the solution to its boiling point. This is because MgCl2 has the lowest specific heat capacity thus will use the least

Salt Water Intrusion and Salination By: Ryan Tallman University of Phoenix 2009 In this modern world we are faced with many different issues. Sometimes we forget that the majority of our earth is covered in oceans and freshwater. Almost two thirds of the world’s population lives within 250 miles of an ocean coastline. One of the many issues we are facing in our waters is saltwater intrusion and salinization. Saltwater intrusion and salinization is defined as the increase of chloride ion concentrations

Salt Water or Fresh Water‚ Which Would You Prefer? Many people wonder‚ what big differences are between salt water and fresh water? Is it just water with salt versus water without salt? Those are some common questions people have. Most people ask about the differences‚ but they forget about the similarities of salt water and fresh water‚ as well. Did you know that Salt water and fresh water have very different plant and animal life? There are also a few complex fish that can live in both

Erica Mitchell Mr. Vredenburgh Period 5 52/55 The Effect of Carbon Dioxide on Salt Water Abstract Background: The human population strongly relies on the oceans for food‚ transportation‚ recreation‚ climate regulation‚ and half of the Earth’s oxygen. These oceans‚ that we rely so heavily on‚ are becoming more acidic and less hospitable‚ making ocean acidification the world’s second most important atmospheric carbon problem. This carbon is released into the atmosphere by burning fossil fuels
