Arrangement of silver, air, aluminium and lead in order of increasing ...
According to their thermal conductivity for Air, k = 0.022 W/mK
for Aluminium, k = 205 W/mK
for Silver, k = 407 W/mK
Hence correct sequence is
Air, Lead, Aluminium, Silve
for Aluminium, k = 205 W/mK
for Silver, k = 407 W/mK
Hence correct sequence is
Air, Lead, Aluminium, Silve

Arrangement of silver, air, aluminium and lead in order of increasing thermal conductivity at room temperature:
The correct arrangement of silver, air, aluminium, and lead in order of increasing thermal conductivity at room temperature is:
d) Air, Lead, Aluminium, Silver
Explanation:
Thermal conductivity:
Thermal conductivity is the property of a material that determines how well it conducts heat. It is a measure of how quickly heat can pass through a material.
Factors affecting thermal conductivity:
The thermal conductivity of a material depends on various factors, including the molecular structure, density, and specific heat capacity. Generally, materials with higher thermal conductivity allow heat to transfer more easily.
Arrangement:
To determine the arrangement of silver, air, aluminium, and lead in order of increasing thermal conductivity at room temperature, we need to compare the thermal conductivities of these materials.
Air:
Air is a poor conductor of heat compared to solids. It has a very low thermal conductivity.
Lead:
Lead is a metal with relatively low thermal conductivity. It conducts heat less efficiently compared to other metals like silver and aluminium.
Aluminium:
Aluminium is a metal with higher thermal conductivity than lead. It conducts heat relatively well.
Silver:
Silver is an excellent conductor of heat. It has one of the highest thermal conductivities among common metals.
Conclusion:
Based on the information above, we can conclude that the correct arrangement of silver, air, aluminium, and lead in order of increasing thermal conductivity at room temperature is:
Air, Lead, Aluminium, Silver
This means that air has the lowest thermal conductivity, followed by lead, aluminium, and silver being the highest.
The correct arrangement of silver, air, aluminium, and lead in order of increasing thermal conductivity at room temperature is:
