Arrange the thermal conductivity of the following materials in ascendi...
thermal conductivity of a material can be defined as the rate of heat transfer through a unit thickness of the material per unit area per unit temperature difference. The thermal conductivity of a material is a measure of the ability of the material to conduct heat. A high value for thermal conductivity indicates that the material is a good heat conductor, and a low value indicates that the material is a poor heat conductor or insulator. The thermal conductivities of some common materials at room temperature are given as
Kwater < Kmercury < Kcopper < KSilver

Thermal conductivity is a property that measures how well a material can conduct heat. It is defined as the amount of heat transfer per unit time through a unit area of material, for a unit temperature gradient.
In this case, we need to arrange the materials in ascending order of their thermal conductivity.
Thermal Conductivity of Copper:
Copper is known for its excellent thermal conductivity. It has a thermal conductivity value of about 401 W/m·K at room temperature. This means that copper can efficiently conduct heat.
Thermal Conductivity of Mercury:
Mercury is a liquid metal with a relatively low thermal conductivity. It has a thermal conductivity value of about 8.3 W/m·K at room temperature. Although it is a metal, its thermal conductivity is much lower than that of copper.
Thermal Conductivity of Silver:
Silver is another metal known for its high thermal conductivity. It has a thermal conductivity value of about 429 W/m·K at room temperature. This makes it even more conductive than copper.
Thermal Conductivity of Water:
Water is a liquid with a relatively low thermal conductivity compared to metals. It has a thermal conductivity value of about 0.6 W/m·K at room temperature. This means that water is a poor conductor of heat compared to metals like copper and silver.
Arranging the Materials in Ascending Order:
Based on the thermal conductivity values mentioned above, we can arrange the materials in ascending order as follows:
Water, Mercury, Copper, Silver
Explanation:
- Water has the lowest thermal conductivity value among the given materials.
- Mercury has a higher thermal conductivity than water but lower than copper and silver.
- Copper has a higher thermal conductivity than mercury and water, but lower than silver.
- Silver has the highest thermal conductivity among the given materials.
So, the correct answer is option 'C': water, mercury, copper, silver.
In this case, we need to arrange the materials in ascending order of their thermal conductivity.
Thermal Conductivity of Copper:
Copper is known for its excellent thermal conductivity. It has a thermal conductivity value of about 401 W/m·K at room temperature. This means that copper can efficiently conduct heat.
Thermal Conductivity of Mercury:
Mercury is a liquid metal with a relatively low thermal conductivity. It has a thermal conductivity value of about 8.3 W/m·K at room temperature. Although it is a metal, its thermal conductivity is much lower than that of copper.
Thermal Conductivity of Silver:
Silver is another metal known for its high thermal conductivity. It has a thermal conductivity value of about 429 W/m·K at room temperature. This makes it even more conductive than copper.
Thermal Conductivity of Water:
Water is a liquid with a relatively low thermal conductivity compared to metals. It has a thermal conductivity value of about 0.6 W/m·K at room temperature. This means that water is a poor conductor of heat compared to metals like copper and silver.
Arranging the Materials in Ascending Order:
Based on the thermal conductivity values mentioned above, we can arrange the materials in ascending order as follows:
Water, Mercury, Copper, Silver
Explanation:
- Water has the lowest thermal conductivity value among the given materials.
- Mercury has a higher thermal conductivity than water but lower than copper and silver.
- Copper has a higher thermal conductivity than mercury and water, but lower than silver.
- Silver has the highest thermal conductivity among the given materials.
So, the correct answer is option 'C': water, mercury, copper, silver.
