gas laws

Most DAT students get this wrong — and it costs easy points on test day. Gas laws are often memorized instead of understood, which leads to mistakes when the questions become slightly more complex. This quick breakdown shows a simple way to approach these problems so you actually understand...

Answer is C Quick DAT Question of the Day (General Chemistry): Root mean square speed is given by: vrms=3RTMv_{rms} = \sqrt{\frac{3RT}{M}}vrms=M3RT Consider nitrogen and hydrogen at 35°C. At what temperature would they display equal RMS speed? (See the slides below for the full setup...

At constant pressure, the ratio between the volume expansion of a mole of gas with a high Cp to that of a mole of gas with a low Cp for a given heat input will be a) greater than 1 b) less than 1 c) equal to 1 equations given: Q= nCp delta T equations that come to mind: since Pressure and...

an open ended mercury barometer has a height of 205 mm with the injection of a gas at 565 mmhg. The liquid in the arm, which is exposed to the air, has a height of 45 mm at the same temperature. What is the atmospheric pressure in torr? Thank you in advance for all responses :)
