Consider that you have a balloon containing 2.00 moles of CO and 1.00 mole of O2 which is in a room that has a temperature of 26.6oC and a pressure of 1.00 atm. Then, the following reaction occurs inside the balloon to completion: 2 CO(g) + O2(g) -> 2 CO2(g). Calculate the change in work due to the reaction occurring inside the balloon. Enter your answer to three significant figures and in units of kJ. -Enter 3 significant figures unless...

A1. An ideal gas is slowly compressed at a constant pressure of
from 2.5
L to 1.0 L. Heat is then added to the gas, holding the volume
constant, until its pressure reaches 1.5×10^5 Pa. How much total
work (J) is done on the gas?

answer asap please
A sealed balloon is filled with air at atmospheric pressure (P = 1.01 X 105 Pa) at 30°C (typical conditions for the surface of the Earth in St. Thomas). You take the (sealed) balloon with you on top of Mountain Top, which has an elevation of about 450m, where the average air pressure is 9.6 x 109 Pa. The temperature at the top is 26°C, a bit cooler. 2.5 pts. - a) How big is the balloon...

A helium balloon ride lifts up passengers in a basket. Assume the density of air is 1.28 kg/m and the density of helium in the balloon is 0.18 kg/m. The radius of the balloon (when filled) is R-5 m. The total mass of the empty balloon and basket is my - 124 kg and the total volume is Vn 0.061 m. Assume the average person that gets into the balloon has a mass mp - 70 kg and volume Vp...
