20 4 Moles Of O2 Gas Initially With A Volume Of 0 05 Ur Is Under A Pressure Of 1 5 X 10 Pa It Is Then Compressed At Co 1 (20.55 KiB) Viewed 11 times

20. 4 moles of O2 gas initially with a volume of 0.05 ur is under a pressure of 1.5 x 10 Pa. It is then compressed at constant pressure to 0.03 m Assume the Ogas behrves as an ideal gas. How much heat is input and what is the change in internal energy during the compression? A) AQ = - 4500.J, AU = 3000J. B) AQ --3000J, AU = 45001 C) AQ = 7500J, AU = 3000J. D) AQ = -7500J, AU = -4500J. E) AQ 4500J, AU --3000J. 21. If the absolute pressure of an ideal gas is tripled while the absolute temperature of the gas is doubled, the volume occupied by the gas A) change by a factor of 6. B) change by a factor of 3/2 C) change by a factor of 2/3 D) change by a factor of 1/6. E) We need to know the number of molen will
