For answering this question you need to use the next law: PV = nRT V, R, n are constants P is pressure T is temperature From the first law: P1/T1 = P2/T2 T2 = P2/(P1/T1) So the answer is T2 = 36.6

A sample of gas has a pressure of 2.9 atm and a temperature of 435K. What will be the new temperature if the pressure is increased to 4.0 atm?

Using Gay-lussac law,P1/T1 = P2/T22.9/435 = 4.0/T2T2 = 600 KSo, New temperature is = [600] K

A given amount of oxygen gas has a volume of 25.0 L at a temperature of 37oC and a pressure of 1.0 atm. At what temperature would this gas occupy a volume of 22.0 L at a pressure of 1.0 atm?

P1V1/T1 = P2V2/T2P1 = 1 atmV1 = 25 LT1 = 37+273 = 310KP2 = 1 atmV2 = 22 LT2 = ?= 1×25/310 = 21×1/X= 0.080645 = 21/X0.080645X = 21X =...

A gas exerts a pressure of 2.0 atm, at 30°C, in a 10 L container. In what size container would the same amount of gas exert a pressure of 4.0 atm at 20° C?

Using the gas law: pV = nRT, and keeping the same number of moles of gas (n),we find the final volume V2:V2 = (T2/p2)*(p1*V1/T1) = (293 K/ 4.0 atm)*(2.0 atm...

A mixture of four gases exerts a total pressure of 860mmHg. Gas A and B each exert 220mmHg. Gas C exerts 110mmHg. What pressure is exerted by gas D?

For this task we use the Dalton’s law which says that total pressure of mixture of gases equals to the sum of partial pressures of individual gases: Ptotal=PA+PB+PC+PD Therefore PD...

A sample of a gas occupies a volume of 1100 mL at 78ºC and 0.060 atm. What would be the new volume if the temperature decreased to 44ºC and the pressure increased to 1.31 atm?

p1 = 0,06 atm = 6079,5Pa V1 = 1100ml = 0,0011m3 T1 = 780C = 351 K p2 = 1,31 atm = 132735,8Pa T2 = 440C = 317 K V2...
