FAQs on Thermal conductivity HMT Tutorial- 5, Heat and Mass Transfer, Mechanical Engineering, GATE Video Lecture - Topper Handwritten Notes & Videos for GATE ME
| 1. What is thermal conductivity? |  |
Ans. Thermal conductivity is the property of a material to conduct heat. It is a measure of how quickly heat can pass through a material. Materials with high thermal conductivity allow heat to flow easily, while materials with low thermal conductivity do not allow heat to pass through quickly.
| 2. How is thermal conductivity measured? | |
Ans. Thermal conductivity is typically measured using a device called a thermal conductivity meter or a heat flow meter. These devices measure the heat transfer through a material and calculate the thermal conductivity based on the temperature difference, the thickness of the material, and the area of heat transfer.
| 3. What factors affect the thermal conductivity of a material? | |
Ans. The thermal conductivity of a material is influenced by several factors, including the material's composition, structure, and temperature. Generally, materials with higher densities, greater atomic or molecular bonding, and lower porosity tend to have higher thermal conductivity. Additionally, an increase in temperature usually leads to an increase in thermal conductivity.
| 4. How does thermal conductivity impact heat transfer in engineering applications? | |
Ans. Thermal conductivity plays a crucial role in heat transfer in various engineering applications. It determines how efficiently heat can be transferred between different components or surfaces. For example, in heat exchangers, materials with high thermal conductivity are used to facilitate efficient heat transfer between a hot fluid and a cold fluid. In insulation, materials with low thermal conductivity are utilized to minimize heat transfer and maintain temperature control.
| 5. What are some common materials with high thermal conductivity? | |
Ans. Some common materials with high thermal conductivity include metals such as copper, aluminum, and silver. These metals are frequently used in heat sinks, electrical cables, and cooking utensils due to their excellent heat transfer properties. Other materials like diamond, graphite, and some ceramics also exhibit high thermal conductivity.

item idea this is a very short video in
this video I'll share with you about
thermal conductivity thermal
conductivity right as you know thermal
conductivity Here I am going to do like
this here point wise that's why you can
understand about it okay now what is
thermal conductivity basically thermal
conductivity is something which is
having ability ability of the material
of the material material to material to
allow to allow heat transfer heat energy
or heater transfer mass heater the
transfer to get conducted to it right so
thermal conductivity is something which
is which allowed to transfer for
together of a solid or liquid Malia's
because they are three process when
conduction process every their thing
come in in all of the Metra the three
types of matter solid liquid and gas in
all of the matter conduction process can
takes place I have already shared and I
will also explain all those things in my
next video
but today thermal conductivity what is
I've already shared with you know what
is the unit of thermal how we can denote
thermal conductivity that is we can
denote thermal conductivity by three now
third what is the unit of thermal
conductivity that is what per meter
Kelvin all these 3 things are most
important in case of thermal
conductivity when one more thing one
more thing right if there are two two
particles or two substance I must say
one is tio and another one is alloy then
thermal conductivity of pure is always
greater than thermal conductivity of
alloys if you wanted to know example
then thermal conductivity of copper is
always greater than thermal conductivity
of brass or bronze or bronze because
brass is also known as bonds so this is
all about thermal
with the I hope you understand some
basic concept about the thermal
conductivity so in my next lecture I
will share with you couple of more
videos needed to connection hope you are
enjoying heat and mass transfer thanks
