    DAT DAT Question of the Day — RMS Speed (Gases) | Dr. Jim Romano | DAT Destroyer | OAT Destroyer

    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...

    Don't understand this MCAT practice question :/

    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...

    AP Chem problem! Please help! About barometers and gas laws

    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 :)
