Asample of helium gas occupies a volume of 156.0 ml at a pressure of 733.0 mm hg and a temperature of 337.0 k. what will the volume be at a pressure of 490.0 mm hg and a temperature of 807.0 k? the combined gas law equation is given below. p1v1 t1 = p2v2 t2 in this equation, p1, v1, and t1 are the initial pressure, volume, and temperature, respectively, and p2, v2, and t2 are the final pressure, volume, and temperature, respectively. ml

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.
