A blueprint shows a horizontal pipe running 10 feet before it connects to a vertical pipe
going 15 feet up.
What is the total length of the piping in this section?
a) 10 feet
b) 15 feet
c) 25 feet
d) 20 feet
c) 25 feet
A canister containing oxygen gas at room temperature (25°C) has a pressure
gauge attached. If we connect the canister to an identical but empty canister,
what would the pressure gauge show?
,Options:
A. Pressure increase.
B. Pressure decrease.
C. Pressure unchanged.
D. Cannot say
According to the Ideal Gas Law:
PV=nRT
Where P =pressure, V = volume, n = number of moles of gas (amount of gas), R =
Gas constant, T = temperature.
Since the amount of gas n (in the system) and the temperature T remain unchanged,
the right side of the equation remains constant.
In order to maintain the equation, the left side of equation must also remain
constant. Thus, since the volume (of the system) has increased the pressure must
decrease, respectively, in order that P*V remains constant.
Please choose the correct answer. If none of the options is the correct answer,
please choose answer choice e, "N".
