# Some facts

**Pressure**determines**the force**that works**perpendicular to the surface**. Mathematically, we can write it down in the following way:

$p = \dfrac{F_p}{S}$where:

**$p$**- pressure,

**$F_p$**- component of force acting perpendicular to the surface,

**$S$**- the area on which force is acting.

- Pressure is
**scalar**. - The pressure is usually marked with the letter
**p**or**P**. - The pressure prevailing in the gas-filled vessel is the
**average force acting on the walls of this vessel**. In this sense, the pressure is thus the**statistical property**. - The basic pressure unit in the SI system is
**pascal**, which is equal to the pressure corresponding to the force of**one newton**acting on the surface of**one square meter**:

$1 Pa = \dfrac{1 N}{1 m^2}$ - The relationship between pressure, temperature, and volume of
**perfect gas**(i.e. one where the particles do not interact with each other) is described by the**Clapeyron's equation**:

$pV = nRT$where:

**p**- pressure,

**V**- volume,

**n**- the number of moles of gas in the system,

**R**- gas constant,

**T**- temperature.
