One mole of an ideal gas initially at a temperature of 1.30 102 °C is compressed at a constant pressure of 2.?
One mole of an ideal gas initially at a temperature of 1.30 102 °C is compressed at a constant pressure of 2.00 atm to two-thirds its initial volume.
(a) What is the final temperature of the gas?
K
(b) Calculate the work done on the gas during the compression.
J

(a)
(V1)/(T1) = (V2)/(T2)
V / (130 + 273K) = (2/3)V / (T2)
T2 = (2/3)(403K)
T2 = 269K
(b)
W = -nRΔT
W = -(1 mol)(8.314 J/mol-K)(269 - 403K)
W = 1114 J
once you boost the tension and compress the molecules they start to pass speedier and that will boost the temperature. The gas from is compressible, it won't save an identical volume because it truly is compressed. If the tension stay an identical the quantity stay an identical. you're actually not paying interest in school. in case you have a air compressor with tank, and you turn it on after it truly is administered a whilst, you will no longer be able to touch the air line to tank because it truly is going to burn your hand, turn off the compress and verify the tension. come again interior the morning and you will touch the compressor throughout, it truly is going to likely be cool, recheck the tank tension , and it's always comparable to it replaced into the evening till now. You draw the tip.
