Q: What are kpa, atm, and mmhg measurement units for?


Read this paragraph and choose the correct option from the provided answers:

The value of , the ideal gas constant, depends on the units chosen for pressure, temperature, and volume in the ideal gas equation. It is necessary to use Kelvin for the temperature and it is conventional to use the SI unit of liters for the volume. However, pressure is commonly measured in one of three units: kPa, atm, or mmHg. Therefore, can have three different values.

 Choices:

- temperature

- weight

- velocity

- pressure


A:
pressure
