Which of the following are acceptable units for pressure? Choose all that apply.
atm
lb
N
N/m2
kg
kg/L
psi
tons
Pa
Four of them I see immediately. The only tricky one is Pa which is "Pascals"

Thank you!
The acceptable units for pressure include:
- atm (atmosphere)
- N/m2 (Newtons per square meter)
- Pa (Pascals)
- psi (pounds per square inch)
So the acceptable units for pressure are: atm, N/m2, Pa, and psi.
To determine which of the following are acceptable units for pressure, let's review each option:
1. atm (atmosphere): Atmospheric pressure is commonly used as a unit of pressure. It represents the average pressure exerted by the Earth's atmosphere at sea level.
2. lb (pound): Although pounds (lb) are a unit of force, they are not generally used to express pressure. Therefore, lb is not an acceptable unit.
3. N (newton): Newton is a unit of force, not pressure. So N is not an acceptable unit for pressure.
4. N/m2 (newton per square meter): This unit represents the SI unit of pressure known as pascal (Pa). It is widely used in scientific and engineering applications.
5. kg (kilogram): Kilogram is a unit of mass, and it is not used for measuring pressure. So kg is not an acceptable unit for pressure.
6. kg/L (kilogram per liter): Kilograms per liter are a unit of density, not pressure. Therefore, kg/L is not an acceptable unit for pressure.
7. psi (pounds per square inch): PSI is a commonly used unit of pressure in the United States and some other countries. It represents the pressure exerted by a force of one pound on an area of one square inch.
8. tons: Tons are a measure of weight, not pressure. Therefore, tons are not an acceptable unit for pressure.
9. Pa (pascal): Pascal is the SI unit of pressure. It is commonly used in scientific and engineering applications. One pascal is equal to one newton per square meter (Pa = N/m2).
Based on this analysis, the acceptable units for pressure are: atm, N/m2, psi, and Pa.
