An atmospheric column that is heated will _______________ while one that is cooled will ________________, in order to maintain hydrostatic balance.
Homework Answers
Answer : An atmospheric column that is heated will rise while one that is cooled will sink, in order to maintain hydrostatic balance.
Explanation : Warm air rises and cold air sinks due to the pressure difference created by differential heating.
Add Answer to:

One means of producing liquid oxygen from atmospheric air is to
take advantage of the phase equilibrium properties of
oxygen-nitrogen mixtures. This system is illustrated in Fig.
P16–121. In this cascaded-reactors system, dry atmospheric air is
cooled in the first reactor until liquid is formed. According to
the phase-equilibrium properties, this liquid will be richer in
oxygen than in the vapor phase. The vapor in the first reactor is
discarded while the oxygen enriched liquid leaves the first reactor
and...

Hot air balloons rise when atmospheric gases are heated, typically by burning propane, and the density of the gases decreases. While you are watching one of these balloons rise, a large rip appears. Which of the following atmospheric gases present will be the first to escape? Argon (Ar), Carbon dioxide (CO2), Nitrogen (N2), or Oxygen (O2) ? State you answer, then briefly explain why you chose your answer.

1.1) cylinder is heated on one end and cooled on the other. The heater is powered by 12 ± 0.05 V and 2.5 ± 0.1 A. A mass flow rate of 0.07 ± 0.01 L/s of water (cp = 4200 ± 20 J / kgK ) is used for cooling, experiences a temperature difference of AT = 8.7 ± 0.1°C. Determine the heat loss between the heater and the water, and find the uncertainty. 1.2)The cylinder in the "1.1" question,...

Steel is sequentially heated and cooled (annealed) to relieve stresses and to make it less brittle. Consider a 100-mm-thick plate (k = 45 W/m.K, p= 7800 kg/m3, cp = 500 J/kg.K) that is initially at a uniform temperature of 180°C and is heated (on both sides) in a gas-fired furnace for which T. = 700°C and h= 500 W/m2.K. How long will it take for a minimum temperature of 550°C to be reached in the plate? sec. It will take...

7.33 A square (10 mm × 10 mm) silicon chip is insulated on one side and cooled on the opposite side by atmospheric air in parallel flow at u 20 m/s and T 24°C. When in use, electrical power dissipation within the chip maintains a uniform heat flux at the cooled surface. If the chip temperature may not exceed 80°C at any point on its surface, what is the maximum allowable power? What is the maximunm allowable power if the...
