How high a column of methanol would be supported by a pressure that supports a mm column of mercury? A As air becomes thinner, its density decreases.

B Air actually has weight. C With an increase in altitude, atmospheric pressure increases as well. D The warmer the air, the lower the atmospheric pressure. E Atmospheric pressure prevents water in lakes, rivers, and oceans from boiling away.

A C E The reaction of 6. A few milliliters of an easily vaporized liquid are added to the flask and the flask is immersed in a boiling water bath. All of the liquid vaporizes at the boiling temperature of water, filling the flask with vapor. When all of the liquid has vaporized, the flask is removed from the bath, cooled, dried, and reweighed. The new mass of the flask and the condensed vapor is Which of the following compounds could the liquid be?

Assume the ambient pressure is 1 atm. The flask and its contents were then rapidly cooled and reweighed The atmospheric pressure and temperature during the experiment were 0.

Which of the following cannot be used to fill a balloon that will float in air at STP? What is the mole fraction of if the partial pressures of Xe and Ar are 1. A the rms speed B the square of the rms speed C the square root of the rms speed D the square of the particle mass E the particle mass. A the average kinetic energy of the gas molecules decreases B the gas molecules collide more frequently with the wall C the gas molecules collide less frequently with the wall D the gas molecules collide more energetically with the wall E both the gas molecules collide more frequently with the wall and the gas molecules collide more energetically with the wall.

E None. The molecules of all gases have the same root-mean-square speed at any given temperature. A double B increase by a factor of 1. A Atoms are neither created nor destroyed by ordinary chemical reactions. B Attractive and repulsive forces between gas molecules are negligible. C Gases consist of molecules in continuous, random motion.

D Collisions between gas molecules do not result in the loss of energy. This ensures you quickly get to the core! Quickly navigate to. Preview 4 out of pages. View example.
