Which of the following is a correct definition of Pascal's principle?A change in pressure applied to an enclosed fluid is transmitted undiminished to all portions of the fluid and to the walls of its container.A change in pressure applied to an enclosed fluid is transmitted to all portions of the fluid, but may change in magnitude.A change in pressure applied to an unenclosed fluid is transmitted undiminished to all portions of the fluid and to the walls of its container. A change in pressure applied to an enclosed fluid is never transmitted to all portions of a fluid; some of the pressure is always lost.Pressure equals force divided by area.
Question
Which of the following is a correct definition of Pascal's principle?A change in pressure applied to an enclosed fluid is transmitted undiminished to all portions of the fluid and to the walls of its container.A change in pressure applied to an enclosed fluid is transmitted to all portions of the fluid, but may change in magnitude.A change in pressure applied to an unenclosed fluid is transmitted undiminished to all portions of the fluid and to the walls of its container. A change in pressure applied to an enclosed fluid is never transmitted to all portions of a fluid; some of the pressure is always lost.Pressure equals force divided by area.
Solution
Para responder a la pregunta, primero debemos entender qué es el principio de Pascal. El principio de Pascal establece que cuando se aplica un cambio de presión a un fluido encerrado, este cambio de presión se transmite sin disminución a todas las partes del fluido y a las paredes de su contenedor.
Ahora, revisemos cada una de las opciones proporcionadas:
-
"A change in pressure applied to an enclosed fluid is transmitted undiminished to all portions of the fluid and to the walls of its container."
- Esta opción coincide con la definición del principio de Pascal.
-
"A change in pressure applied to an enclosed fluid is transmitted to all portions of the fluid, but may change in magnitude."
- Esta opción es incorrecta porque el principio de Pascal establece que el cambio de presión se transmite sin disminución.
-
"A change in pressure applied to an unenclosed fluid is transmitted undiminished to all portions of the fluid and to the walls of its container."
- Esta opción es incorrecta porque el principio de Pascal se aplica a fluidos encerrados, no a fluidos no encerrados.
-
"A change in pressure applied to an enclosed fluid is never transmitted to all portions of a fluid; some of the pressure is always lost."
- Esta opción es incorrecta porque contradice el principio de Pascal.
-
"Pressure equals force divided by area."
- Esta opción es una definición de presión, no del principio de Pascal.
Por lo tanto, la opción correcta es la primera: "A change in pressure applied to an enclosed fluid is transmitted undiminished to all portions of the fluid and to the walls of its container."
