3927C If 62 moles of an ideal gas expands isothermally at 1

. 39.27°C If 6.2 moles of an ideal gas expands isothermally at 110°C to 6.7 times its initial volume, then find the heat flow into the system. DMIR 9. a. 40720J b. 41080 d. 38890J f. 45400 nar 37550 MXJTI Gas in a container expands at a constant pressure of 2.atm. Find the work done (in joules) by the gas f the initilal olume is 3.5 m3 and the final volume is 5.5.m2. 10. a. 422900J b. 462100.J d. 616300 e. 587500 f. 298000,J C. 405200J

Solution

yes you are right for 9.

10)2 atm = 2*1.01 *10^5 =2.02 * 10^5 Pa.

work done - Pdv= 2.02 * 10^5 *(5.5-3.5) = 4.04 *10^5 ~~ 405200 J so C is answer
