Has said in the past 4 days:
-Our air is 70% oxygen
Umm, actually it's 21%
-A final exam in a chemistry course at Harvard or Standard had the question "What is the chemical formula for ice?" and 70% of the students got it wrong.
I highly doubt it
-We cook noodles in salt water because it lowers the boiling temperature which makes them take in water better.
Salt water makes the boiling temperature higher
-Ice melted at 19*C in our lab because it had minerals in it (it was tap water and by the time all the ice melted and the water was stirred, it was 19*C)
Water around the ice could raise temperature at a faster rate than the ice because the ice was undergoing a phase change, as soon as the ice was now all liquid, the rest of the water had a chance to be really hot. We had the water on a good hot plate...
-THE four nonmatter things are sound, light, kinetic energy, and potential energy
WTF happened to all the other fundamental forces, and what's with the question anyway? I could say that time is nonmatter, the question doesn't make too much sense.
-Food poisoning results when your water temperature is too high, and you should add salt to water in order to lower the boiling temperature.
If the temperature at which water boiled was lower, a lot of bacteria would probably survive the experience and then you COULD get food poisoning.
-A BUNCH of other stuff which I do not remember.
Whenever any of us question her (only about three people in the class ever do, the rest take her word as high as god's, because she is a teacher so she must be correct, right? right?lol), she says some example (like the food poisoning one) or says something about some study which never happened, or she just dismisses us and says something else and goes on.
