If you can me answer any of these i’d appreciate it so much!
(picture for only 36 to 37 )
items 36 and 37 relate to the pressure and amounts of two gases, a and b in the sphericle glass bulbs shown in the following diagram.
bulb a:
2 liters volume
27 celsius temperature
1.0 atmosphere of pressure
bulb b:
4 liters volume
27 celsius temperature
0.5 atmosphere of pressure
36. when the valve is opened to connect the two bulbs the statement concerning the system that is false is
a. the gases will mix in the overall pressure will change.
b. after the final pressure is reached gas molecules will no longer move back and forth between bulbs a and b.
c. the final pressure in bulb a will be the same as the final pressure in bulb b.
d. the final pressure in bulb b will be between 0.5 atmosphere and 1.0 atmosphere.
e. none of these statements are false.

37. if the temperature of the system is increased with the valve connecting the two bulbs open the statement that is false is
a. the average velocity of the gas molecules will be increased.
b. the average kinetic energy of the molecules will be increased.
c. the density of the gases will be increased.
d. there will be more frequent collisions between molecules of gas a and b.
