Suppose the ideal monatomic gas expands adiabatically and irreversibly. in this case the initial and final pressure/temperatures/volumes are not related by either of the equations given in the introduction. if an ideal gas expands irreversibly against a constant external pressure of pext, the initial volume v1 and initial temperature t1 are related to the final volume and temperature v2 and t2 by ncv(t2−t1)=−pext(v2−v1) . suppose 5.15 moles of an ideal monatomic gas expands adiabatically and irreversibly from an an initial temperature of t1=473k and an initial volume of v1=20.0l against a constant external pressure of pext=1.00 atm. assume the expnsion continues until the final temperature is t2=303k. calculate v2, the final volume of the gas. give your answer in si units.

when earth is in rotational motion around the sun,it displaces from its place.

when a ball is placed on an inclined surface it does both the rotational and circular motion.

explanation:

force is based upon mass and acceleration.the statement is not always true.

it can be explained from newton's second law of motion.

as per newton's second law of motion the rate of change of momentum is directly proportional to the applied force and takes place along the direction of force.

mathematically it can be written as -

                                              ⇒      

here   k is the proportionality constant whose value is 1.

                                                            [a is the acceleration=dv/dt]

hence we see that force not only depends on mass and acceleration but also on velocity and rate of change of mass. force f will depend on mass and acceleration only when mass is constant.

hence the statement that force is based upon mass and acceleration is false.
