Cuando el pistón tiene un volumen de 2x10^-4 m^3, el gas en el pistón está a una presión de 150 kPa. El área del pistón es 0.00133 m^2. Calcular la fuerza que el gas ejerce sobre el embolo del pistón.

Answer:

F = 1.128 10⁸ Pa

Step-by-step explanation:

Pressure is defined by

P = F / A

If the gas is ideal for equal force eds on all the walls, so on the piston area we have

F = P A

We reduce the pressure to the SI system

P = 150 kpa (1000 Pa / 1kPa = 150 103 Pa

we calculate

F = 150 10³ / 0.00133

F = 1.128 10⁸ Pa
