# Water - Thermal Conductivity

## Figures and tables showing thermal conductivity of water (liquid and gas phase) with varying temperature and pressure, SI and Imperial units

Thermal conductivity is a material property that describes ability to conduct heat. Thermal conductivity can be defined as

"the quantity of heat transmitted through a unit thickness of a material - in a direction normal to a surface of unit area - due to a unit temperature gradient under steady state conditions"
