The instant you open the can the solute escapes and the pressure decreases...umm where does water factor in with the first question? and could you please look over my answer (2nd post) and see if its okay... when the water is heated there's water in liquid and gaseous states. When cold water...

okay i tried to talk my way through the first one and came up with this: When the cans were placed in the freezer, the temperature decreased drastically, and with it the kinetic energy of the soda molecules. As the temperature decreases, the solubility of the gas increases, and more of the gas...

IDEA...would the first one be b/c of freezing point depression? the solute and solvent have different FP's, and when the solute is in solution it prevents freezing but when the can is opened the solute is released and the solvent freezes...? i was trying to talk my way through it and this is...

these are really intestesting but i have no clue what the answers are... 1. You are having some friends over, so you venture to the store to purchase some soda and snacks. Unfortunately the only pop available is at room temp. In order to cool the cans of soda quickly you place the cans in the...

AP Chemistry -two interesting questions -- PLEASE HELP! Homework Statement 1. You are having some friends over, so you venture to the store to purchase some soda and snacks. Unfortunately the only pop available is at room temp. In order to cool the cans of soda quickly you place the cans in...

Please Help If You Can Thanks

Homework Statement The ball launcher in a pinball machine has a spring that has a constant of 1.2 N/cm. The surface on which the ball moves is inclined 10 degrees with respect to the horizontal. If the spring is initially compressed 5.0 cm, find the launching speed of a 100g ball when the...

Never mind i realized what you are doing is the same thing...d/t (distance/time) is velocity. You just replaced d/t with V. Wow that was a stupid question. But thanks again for the help.

Thanks a million. But just out of curiosity is there a way to do it just using the equations W = Fd and P = W/t ?

Thermodynamics -- simple question Homework Statement An elevator motor prouces 2000 W of power. How fast ( in m/s) can it life a 1000 kg load? Homework Equations W = Fd P = W / t The Attempt at a Solution by rearranging the formula i got: W = Fd / t d / t = W / F but...

Really? I would think no change...i mean can it really absorb the overflow crystals from teh bottom and grow??

I was looking through some AP Chem materials and tehre were a lot of questions regarding colors of solutions. Is there some handy dandy guide I can use to figure out the colors of various aqueous solutions? and also the colors of various compounds when the burn? We really don't touch upon...

At this step: you need to use the molar heat of fusion (melting) rather than vaporization to get the compound to the liquid state. then use this part: to get the substance to its boiling point. at this point you need to do q = n(molar heat of vaporization) to vaporize the substance...

Homework Statement yes this question is a bit ridiculous but stick with it please... After watching the movie "Corcodile Dundee" you and some friends decide to make a communications device invented by the Austrailian Aborigines. It consists of a noise-maker swung in a vertical circle on the...

Why not declare a general psych major and then figure out what you want to do and specify your major later? and to answer i think clinical is the most well paid and as far as most advanced that depends on what you mean by advanced. and also looking at your description it looks like...
