Question

what is pressur? write its si unit?​

Answer 1

Answer:

Pressure—the effect of a force applied to a surface—is a derived unit, obtained from combining base units. The unit of pressure in the SI system is the pascal (Pa), defined as a force of one Newton per square meter. The conversion between atm, Pa, and torr is as follows: 1 atm = 101325 Pa = 760 torr.
