Question

a fixed quantity of gas at 21c exhibits a pressure of 752 torrand occupies a volume of 4.38L A) use boyle's law to calculate the volume the gas will occupyif the presssure is increased to 1.88 atm while the tempearture isheld constand b) use charles law to calculate the volume the gas will occupyif teh temperature is increased to 175c while the pressure is heldconstand a) - boyles law p1v1 = p2v2        (752/760) * 4.38 =1.88 * x         is thatcorrect? b) charles law v1/t1 = v2/t2       4.38/(21+273) = v/(273+175) is that correct? a fixed quantity of gas at 21c exhibits a pressure of 752 torrand occupies a volume of 4.38L A) use boyle's law to calculate the volume the gas will occupyif the presssure is increased to 1.88 atm while the tempearture isheld constand b) use charles law to calculate the volume the gas will occupyif teh temperature is increased to 175c while the pressure is heldconstand a) - boyles law p1v1 = p2v2        (752/760) * 4.38 =1.88 * x         is thatcorrect? b) charles law v1/t1 = v2/t2       4.38/(21+273) = v/(273+175) is that correct?

Explanation / Answer

(A) Given temp. ,T = 25o C = 25 + 273 K

Initial pressure ,P = 752 torr = 752 / 760 atm = 0.9894atm

Initial volume = 4.38 L
