Question

which of the following are acceptable units for pressure? choose all that apply. kg kg/l n atm lb n/m² psi tons pa

Explanation:

• \( \text{kg} \): Unit of mass, not pressure.
• \( \text{kg/L} \): Unit of density, not pressure.
• \( \text{N} \): Unit of force, not pressure (though pressure involves force over area).
• \( \text{atm} \): Standard unit for pressure (atmosphere).
• \( \text{lb} \): Unit of force/mass (imperial), not pressure alone.
• \( \text{N/m}^2 \): SI unit of pressure (equivalent to Pascal, \( \text{Pa} \)).
• \( \text{psi} \): Pound - force per square inch, unit of pressure.
• \( \text{tons} \): Unit of mass, not pressure.
• \( \text{Pa} \): SI unit of pressure (Pascal, equal to \( \text{N/m}^2 \)).

Answer:

atm, \( \text{N/m}^2 \), psi, Pa
