The air in a 22°c room contains water at a partial pressure of 14 mm hg, what is the relative humidity? 1. (#20 from textbook). a 1000 m2 room at 27°c has a relative humidity of 80%. what mass of water must be removed to reduce the relative humidity to 45%? 2. (#23 from textbook). the weatherman states that the current temperature is 95°f and the dew point is 74°f. what is the current relative humidity? 3. ideal gas law & gaseous mixtures 4 life on planet eitemax is tough. the surface is composed of oceans of nearly pure liquid chloroform (chci) the atmosphere on eitemax acts like an ideal gas and on a chloroform-free basis is composed of a mixture of 35 mole% chlorine (cl) 55 mole% carbon monoxide (co) 10 mole% carbon dioxide (co2) on eitemax, the ambient temperature is 2°f, and the total pressure is 610 mm hg (torr). if the average molecular weight of the chloroform-containing gases in the atmosphere is 50 g/mol, what is the volume of atmospheric gas that contains one kilogram of gas? the air in a 22°c room contains water at a partial pressure of 14 mm hg. what is the mass of the water present in the room? can you solve this problem? why or why not?

The answer to your question really depends on three things: how much water you have, how cold it is to start out, and how cold the things around it are. water actually freezes when it gets to 32 degrees fahrenheit (0 degrees celsius), but the time it takes to get there may be different.  let's start with the first. if you take two glasses, and fill one with a tiny bit of water, and the other about halfway, then put them both in the freezer, the one with less water will freeze first (you can try this at home, but i recommend using plastic cups and not glass ones).  now let's move on to the second part. let's say you have two glasses, and you fill one with really cold water that has been in the refrigerator, and the other with really hot water from the sink. if you put both of them in the freezer, the one that started out colder will freeze first.  for the third part, let's imagine that you have two glasses with the same amount of water in them, and the water is at the same temperature. imagine putting one outside on a really really cold day in georgia, and having a friend in alaska put one outside on the same day. since it would be so much colder in alaska, the glass of water there would freeze before yours.  so, if you took a tiny bit of really cold water in a glass, and put it outside on a cold day in alaska, it would freeze a lot faster than a big glass of hot water outside on a cold day in georgia. 

Each calcium ion has a charge of +2, which can also be written as ca2+. if those ions move out of the neuron and no other ions are moving, the neuron would lose the positive charge associated with those ions and become more negatively charged.
