Answer:
P=11.126 atm
Explanation:
We are given that a compressed gas cylinder containing 1.50 mol methane
Volume of methane in a gas cylinder =3.3 L
Temperature =
We have to find the pressure exert by gas on cylinder
Using ideal gas equation
PV =nRT
Where R= gas constant=0.0821 L-atm/K mol
Substitute all given values
Then we get
P=11.126 atm
Hence, the pressure exert by the gas on cylinder =11.126 atm

Answer:
The work required is -515,872.5 J
Explanation:
Work is defined in physics as the force that is applied to a body to move it from one point to another.
The total work W done on an object to move from one position A to another B is equal to the change in the kinetic energy of the object. That is, work is also defined as the change in the kinetic energy of an object.
Kinetic energy (Ec) depends on the mass and speed of the body. This energy is calculated by the expression:
where kinetic energy is measured in Joules (J), mass in kilograms (kg), and velocity in meters per second (m/s).
The work (W) of this force is equal to the difference between the final value and the initial value of the kinetic energy of the particle:
In this case:
Replacing:
W= -515,872.5 J
<u><em>The work required is -515,872.5 J</em></u>
