- A person taking a reading of the temperature in a freezer in Celsius makes two mistakes: first omitting the negative sign and then thinking the temperature is Fahrenheit. That is, the person reads xC as xF . Oddly enough, the result is the correct Fahrenheit temperature. What is the original Celsius reading? Round your answer to three significant figures.Check Understanding The density of in a Classroom ( p=1.00 and T=20C ) is 1.28 kg/m3. At what pressure is the density 0.600 kg/m3 if the temperature is kept constant?Because humidity depends only on water's vapor pressure and temperature, are the saturation vapor densities listed in Table 13.5 valid in an atmosphere of helium at a pressure of 1.01105N/m2 , rather than air? Are those values affected by altitude on Earth?
- What is the total translational kinetic energy of the air molecules in a room of volume 23 m3 if the pressure is 9.5104 Pa (the room is at fairly high elevation) and die temperature is 21 ? Is any item of data unnecessary for the solution?A helium-filled toy balloon has a gauge pressure of 0.200 atm and a volume of 10.0 L. How much greater is the internal energy of the helium in the balloon than it would be at zero gauge pressure?People buying food in sealed bags at high elevations often notice that the bags are puffed up because the air inside has expanded. A bag of pretzels was packed at a pressure of 1.00 atm and a temperature of 22.0 . When opened at a summer picnic in Santa Fe, New Mexico, at a temperature of 32.0 , the volume of the air in the bag is 1.38 times its original volume. What is the pressure of the air?
- An expensive vacuum system can achieve a pressure as low as 1.00107 N/m2 at 20.0 . How many molecules ale there in a cubic centimeter at this pressure and temperature?An airplane passenger has 100 cm3 of air in his stomach just before the plane takes off from a sea-level airport. What volume will the air have at cruising altitude if cabin pressure drops to 7.50104N/m2 ?As shown below, which is the phase diagram for carbon dioxide, what is the vapor pressure of solid carbon dioxide (dry ice) at -78.5 (Note that the axes in the figure ale nonlinear and the graph is not to scale.)
- (a) What is the vapor pressure of water at 20.0ºC ? (b)What percentage of atmospheric pressure does thiscorrespond to? (c) What percent of 20.0ºC air is water vapor if it has 100% relative humidity? (The density of dry air at 20.0ºC is 1.20 kg/m3 .)(1) Hydrostatic balance states Op Əz Equation -1 where p is pressure, z is altitude, p is density and g is the acceleration due to gravity. It can be shown that the reciprocal of hydrostatic balance also applies. That is Equation -2 дz Әр = -Pg, = 1 pg Use the ideal gas law (p = pRT, where R is the gas constant for dry air and Tis temperature) to eliminate p from (2). (2) Under geostrophic balance, the following balance is approximately satisfied Equation -3 fu=-g ¹ (3) where f is the Coriolis parameter, u is the zonal wind, y is meridional distance and z is altitude. (Note that the derivative on the right hand side is taken at constant pressure.) Differentiate (3) with respect to p, and use your expression from part 1 to obtain an expression relating du/ap and T/ay. This expression is called "thermal wind balance".An iron meteorite melts when it enters the Earth’s atmosphere.If its initial temperature was -105°Coutside of Earth’satmosphere, calculate the minimum velocity the meteoritemust have had before it entered Earth’s atmosphere
