Highest thermal conductivity is of _____
Thermal Conductivity Comparison of Water States
Thermal conductivity is a measure of how effectively a material transfers heat. A higher value indicates better heat conduction.
Heat Transfer Properties: Ice, Water, and Steam
The thermal conductivity of water differs significantly across its common states:
- Solid ice: Possesses a more ordered molecular structure and generally higher density than liquid water.
- Liquid water: Molecules are less ordered than in ice.
- Steam (gaseous water): Molecules are widely spaced, leading to low density and poor heat conduction.
Identifying Highest Thermal Conductivity
The trend for thermal conductivity is generally:
Solid > Liquid > Gas
Applying this to water:
Solid ice > Liquid water > Steam
Typical thermal conductivity values (units: Watts per meter Kelvin, W/m·K) illustrate this:
Solid ice: Approximately 2.2 W/m·K
Liquid water: Approximately 0.6 W/m·K
Steam: Approximately 0.025 W/m·K
Consequently, solid ice has the highest thermal conductivity among the options provided.
