Ok, so I was doing the typical boiling point elevation experiment by addind salt to water.

This is supposed to raise the boiling point.

However, I noticed no raise in boiling point.

I was using 2 pints of water, and 4 tablespoons of salt.

I dissolved the salt thoroughly.

It didn't do anything though.

If anything, it may have lowered the boiling point.

I was using Kosher salt, it's a flaky type of salt.

What I want to know is, what could've happened to not make the boiling point rise, and what are the EXACT (chemical / physical)differences between Kosher (flaky) salt, and the normal grainy salt.

Has anyone noticed the similarity between the old four elements (fire, wind, water, and earth) and the four stages of the elements (solid, liquid, gas, and plasma). Solid - Earth, Liquid - Water, Gas - Wind, and Plasma - Fire. I didn't know if anyone else knew this, or thought of it yet. Does anyone know what i'm talking about?

It is common for public opinion polls to have a cofidence level of 95%, meaning that there is a 0.95 probability that the poll results are accurate within the claimed margins of error. If six different organizations conduct independent polls, what is the probability that all six of them are accurate within the claimed margins of error? Does the result suggest that with a confidence level of 95%, we can expect that almost all polls will be within the claimed margin of error?

Is it only a water problem and if so, exactly what levels does one need to achieve that soft, tasty, foldable pizza? Unless you're from NY/NJ/PA/Conn, you are most likely unfamiliar with the crust problem. I'm told that FL water is hard and NY water is soft. What is the scientific term for the level of minerals in water that determine hardness or softness? Would simply adding some kind of digestible softener do the trick or would other steps need to be taken?

A student was told that dogs can not see color. From everything she had read she believed that this was most likely true but wanted to test it anyway. She developed an experiment using three dogs to test her hypothesis. Her Experiment involved using two identical looking flashlights, one of which had a red lens and the other had a white lens. Her test involved 2 weeks of flashing the red lens flash light and then giving her dogs a treat. After 2 weeks of conditioning she knew that is she flashed the red light her dogs would expect food and salivate. To test this theory she randomly selected either red or white light, flashed it and observed if the dogs salivated or not.

By excess I mean after it has gone and lost some zap through the some wiring, and I do know it depends on how far it travels.
