Question

1.) With the temperature held constant, if pressure on a gas is increased, the volume will ______________. If the pressure of a gas is held constant and the temperature is increased, the volume of the gas will ____________

2.) To what temperature (in °C) would you need to heat a gas that has a pressure of 1.21 atm and volume of 1.59 L at 22.9 °C to have it occupy 2.89 L at 2.53 atm?

3.) A 3.2 L sample of CO2(g) at 23.1 oC expands to what volume at 43.1 oC at a constant pressure of 0.95 atm?

4.) The solid chemicals in a specific air bag create 0.545 moles of gas. To what volume (in L) will the air bag inflate at a pressure of 1.10 atm and a temperature of 293 K.

Explanation / Answer

1. decreases , increases .

2. P1V1/T1 = P2V2/T2

(1.21*1.59/296.15)= (2.89*2.53/X)

T2 = 1125.5 K = 852.5 c

3. v1/T1 = v2/T2

(3.2/296.1) = (v2/316.1)

v2 = FINAL VOLUME = 3.41 l

PV = nRT

(1.1*v) = 0.545*0.0821*293

v = 11.91 l
