Question

A sample of  argon gas occupies a volume of  6.98 L at  51.0°C and  0.780 atm.

If it is desired to  decrease the volume of the gas sample to  5.24 L, while  increasing its pressure to  1.03 atm, the temperature of the gas sample at the new volume and pressure must be ___°C.

Answer 1

-a: using ideal Gas equation pr = nRT 0.780 atm P= bressure Pi = Pf = 1.03 atm r= volume Vi = 6.98 -4 Litre VF = 5.24 Litre ne number of moles of Gas [Do not change.] Mi= mf R = Universal Gas Constant T = Temperature Ti = sic or (973+51)K= 384 K. TA = ? = a) pr= MRT mi = Prvi s na = pery RT RTE =) mi = mf ► het nie e 3 To Pf Vif X Ti Piri 1-03 atm x 5.24 1 x 3024% - 321-26 0.780 atm x 6.986 . 148.2 c/
