Can u answer both?

1. Calculate the mean (velocity squared) of a molecule of nitrogen gas (N2) at room temper- ature (300 K). Remember to use the mass of a single nitrogen molecule (in kilograms) in the calculation, not a mole of them. Avagadro's number might come in useful there. Then take the square root of that number to get a representative velocity. Do not be surprised if the velocity is pretty high. . A warm ideal monatomic gas held in a rigid container cools when placed in a cold bath (source that can absorb thermal energy). The pressure of the gas in the container drops from 400 kPa to 150 kPa. If the gas ends up at 300 K, how warm was it before it was cooled? Since a monatomic gas has a molar specific heat of : R, if there are 0.15 moles of gas in the container, how much energy was lost by the gas to the environment? Hint: this is an isochoric process
