Thermodynamic Temperature and Pressure

Reference states:

• Absolute zero: molecules have no motion
• Absolute vacuum: no pressure is exerted

Absolute scale for temperature:

$$T_{\text{abs}}(K)=T(C)+273.15$$

Pressure is typically done with Pascales:

$$P_{\text{abs}}(\text{Pa})=P_{\text{gage}}+P_{\text{atm}}$$

where $P_{\text{atm}}=101.325\text{ kPa}$.
