Calcular el trabajo termodinámico que se realiza para que una porción de maíz palomero explote dentro de una máquina de palomitas. Si se sabe que la presión que se requiere es de 2.4x10 6 N/m 2 . El volumen inicial es de 300 cm 3 y al reventar su volumen es de 500 cm 3

The answer would be a) -80of

W= fd
where f is an applied force and d is the distance over which it is applied. when a parachuting skydiver is at constant velocity, he is experiencing "terminal velocity", the point at which his acceleration down is canceled out by air resistance. that means that the resisting force of the air is equal to his weight, but in the opposite direction. with this, we can solve for the work done by the force.
w = fd
w = (92.0)(9.81 m/s^2) (325)
w= 2.93 x 10^5 j
the value for work in this case is positive because it is pushing up on the skydiver, who has a downward force of gravity.
therefore the answer is 2.93 x 10^5 j

The actual answer is c force stays the same while direction changes
