Question

AIMOSPHERIC SCIENCES Atmospheric Pressure-Nintende Capable T I just bought my kids an old CRT television-you know, the old school TV with the large glass screen (not LCD or Niatscreen or Plasma), I bought it so that during the winter, when they can't play outside, they can play my original Nintendo NES. Here is my son playing Duckhunt. weighs a lot thanks in part to its very thick glass screen. The glass must be this thick in order to T design, which is composed of a large vacuum tube pressure is The reason for this is due to the CR weight of the atmosphere. T behind the glass screen. Essentially, behind the thick glass screen there is a vacuum where the air approximately 0 mb. My son asked. ..s it thick enough that I can stand on it without it breaking?" My answer was, "Yes, it can support not only your weight, but times your weight" Fill in the blank in the previous sentence by calculating this value using the information below. Show all of your work! Assumptions Average atmospheric pressure in Champaign, IL-14.5 Ibs/in The diagonal dimension of the TV is 35 inches (cormer to comer). Assume the TV screen is a square. My son weighs 39 lbs. Changes in Atmospheric Pressure For each of the situations given below, how would you expect the pressure to change? In the space next to each question, write "increase", "decrease" or "stays the same" 1. Descend in an airplane from cruising altitude to the ground. 2. Living in Puerto Rico as Hurricane Maria's eye approached. 3. Drive from Champaign (elevation 764 feet above sea level) to Chicago, IL (elevation 594 ft above sea level). If you where placed into a hyperbaric chamber to counteract the effects of getting the bends. 4. o 2018 Dept. of Atmospheric Sciences, University of Illinois-Urbana Champaign3

Explanation / Answer

STEP 1 :-

Given : Average atmospheric in Champaign, II = 14.5 lbs/ in² The TV dimension = 35 × 35 in² Son weight = 39 lbs

We know that, Pressure = Force/Area

therefore, Pressure of the son on the TV glass screen = (39 × 14) / (35 × 35) = 0.46 pascal

Total number of the son weight on glass screen without breaking it = 39 / 0.46 = 84.78

STEP 2 :-

My answer was, "Yes, it can support not only your wieght but 84 times your weight!"

STEP 3 : CHANGES IN ATMOSPHERIC PRESSURE

1. The pressure will increases when an airplane descend from cruising altitute to the ground.

2. The pressure was decreased when living in Porto Rico as Hurricane Maria's eye approached.

3. The pressure will increased.

4. The pressure will increase into a hyperbaric chamber.
