AT&T; LTE 11:46 PM Done instructors assessment.pdf A cylinder contains 2.S0L of air at a pressure of 5.00 atmospheres. At what volume, will the air exert a pressure of I atmosphere, at the same semperature? 1 0.500L 750L 12.5L 2.001. 100L A student obtained the following data using the procedure in the experiment Corrected velume of the fask-955.0ml Perform necessary cakulations to fill in the blanks in the following table Syringe Baremetric pressure-950.0 em H:0 System Velume, Height of 0 column, em System Pressure, em H:O PN em-ml Volume, mL 1.9 41.3 50.0 0.0 Skctch and ssplain sh typs of graphs you would get by plotting pressure, P,against volume, V of a gas [pat V on s-asis, Pon y-asis). Use the graph paper D Straight lin Hyperbole curve 3 | Calculate the increase in volume when 2.00L of gas at 20.0 is heated to 353K. Ti, K CHML 142 The following observations were obtained by a student who was testing Charles's l Barometric pressure Volume of hundnar in the flask Vr. 210,0 mL Temperature of hot. dry air T-27,0 Volume of sold dry air in the flask V-28.0 ml. Temperature of cold, dry air T:-7.00 a) Find the velume-to-temperature ratio Sor the volume of the bot, dry air and cold, dry air 28.50 in. Ho b) Are these resulis consistent with Charles's Law O YES D NO

Explanation / Answer

1)
Given:
Vi = 2.50 L
Pi = 5.00 atm
Pf = 1 atm

use:
Pi*Vi = Pf*Vf
5.0 atm * 2.50 L = 1.0 atm * Vf
Vf = 12.5 L
Answer: 12.5 L
