TEAS Science

[nikki9666]

I am taking the TEAS exam next Tuesday. I'm struggling with some of the science stuff and my main problem is calculating the velocity, pressure, volume...etc. Any suggestions? Also, do I need to have these formulas memorized or are they given on the exam?

I would like to know as well. It seems like a lot of information and lots of formulas.

You do not need to know all that for the TEAS. The ATI study manual goes over what you need to know for the science section (which is very random). I didn't have any questions that involved formulas, not too much chemistry and no physics.

No physics here! Zero! I just needed to know what Boyles law was! Know photosynthesis and respiration!!! Is photo- oxidation/ reduction .. Respiration reduction/oxidation etc

Yes, in general you do need to know the equations by memory:

KE = 1/2mv^2 (Kinetic Energy)

PE = mgh (Potential Energy)

H = MxL (Heat of Vaporization..... H=-MxL for removal of heat)

F = 9/5C + 32 (Convert deg C to deg F... and vice-versa!)

0 K = -273 deg C (know conversions from C -> K and vice versa)

PV = nRT (Ideal Gas Law)

P1V1 = P2V2 (Boyles Law)

Note, that I do not see the equations for Ideal Gas and Bolyes Laws in the ATI study manual. But, in my opinion it would be worth remembering. I doubt that you would get a question on the exam that provides a few variables and you must solve for the remaining variable, but who knows! My guess is that it is more likely that you might be asked given a known initial pressure and volume, what happens to pressure as the volume is increased? In this case, I would recall Boyle's law and know mathematically that the pressure must decrease:

P1V1 = P2V2 => P2 = P1V1/V2, thus as we can see increasing V2 would decrease P2.

Maybe this is overkill, but I wanted to know it just in case!

Disclaimer: This list of equations is not intended to be all-inclusive. I am sure there are others.
