learned about how salt affects the freezing point of water. In my science project I wanted to see if salt affected the freezing point of water. I started by doing some experiments. My first experiment was whether tap water or salt water would freeze first. I first started by mixing up the salt water warming it for one minute and warming the tap for one minute also. My second experiment was what ice cube would melt fastest. I started by getting two bowls. Two ice cubes‚ and salt. I began by sprinkling

mean root growth was for water treated B.pumilus and the lowest mean root growth was the salt water treated control. Water treated V.paradoxus has a higher mean root growth compared with salt water‚ with a high margin of error. B.pumilus has the largest difference between root growth between water treated and salt water treated. (Table 1) Table 1: Individual results of Brassica mean root growth (mm). These were treated with Bacillus pumilus and Variovorax paradoxus under water and salt water (100mM

sink if put in salt water? Purpose: I want to know why the egg floats in fresh water and not salt water. I want to know if the egg will float in salt water‚ Also this shows why materials float easier in saltwater and sink in freshwater. Research: Since the egg’s density is higher than the density of freshwater the egg will sink. Density is mass per unit volume‚ which means a measure of how much mater is in a certain volume. If you add enough salt the egg will float again. The salt makes the water

Population Growth The effects of population growth on economic development differ between the developed and developing countries. In the developed countries‚ population growth has enhanced the growth of such economies because they are wealthy‚ have abundant capital and scarcity of labour. O n the contrary the consequences of rapid population growth on the development of LDCs are not the same. Most developing countries are poor‚ capital scarce and labour abundant; and therefore population growth aversely

1. Question: How is the growth rate of bean plants affected by different types of water? 2. Introduction: We are going to be exploring the affect that different type of water have on the growth rate of bean plants. We will be experimenting with two different types of bean plants and testing three different types of water. PH is basically the negative log of hydrogen ion activity used to measure the acidity or basicity. The pH level ranges on a scale from one to fourteen‚ one being most

Salt Sugar Fat is a book written by Michael Moss‚ to inform the audience of the effects of salts‚ sugars and fats on the human race when it is found in foods consumed everyday. Parts of the brain and stimulants such as the bliss point are introduced to inform the reader just how these substances can stimulate the body during the consumption of foods. Large food corporations are brought under fire throughout most of the book as well. The main argument of the book written by Moss is that salt‚ sugar

Effects of soil ph variation on radish plants growth Background information: the soil ph can have 2 different impacts on the growth of plant roots. First and most important is how it affects the concentration of nutrients present in the soil itself. This variable varies depending on the ph tendency‚ in particular‚ nutrients like phosphorous‚ potassium ‚sulphur‚ calcium and magnesium tend to drastically decrease in more acidic ph conditions (<6.0)‚ on the other hand iron‚ manganese‚ boron

Does Adding Salt to Water Make it Boil at a Higher Temperature? Project Design Plan Everyone knows that water boils at 212°F‚ but does adding salt to a pot of water make it boil at a higher temperature? Being a person that cooks frequently at home‚ I wanted to test the debated idea that adding salt to my water will make it boil faster. One of my friends says it does raise the temperature and therefore cooks it faster. My other friend says it only helps it taste better. Literature

Rationale of the study Almost everything these days is powered by electricity‚ and while this has certainly improved the quality of life‚ it has its downfalls as well. Some examples are: its effects on our Earth such as global warming‚ the rising bills caused by using too much electricity‚ and so much more. This is the reason why our group has decided to do a research on alternatives for energy source‚ specifically by means of saltwater or saline solution. We believe that this will help us decrease
