What is thermal conduct?
The rate at which heat flows through a material between points at different tempatures
conclusion and recommendation of lab heat transfer of first law termodynamics?
Conclusion The lab experiment on heat transfer of first law thermodynamics has demonstrated that heat energy can be transferred from one body to another through conduction, convection, and radiation. The data collected in this experiment shows that the rate of heat transfer is determined by the thermal conductivity of the material, the surface area of the material, and the temperature difference between the materials. The results of the experiment suggest that the higher the thermal conductivity of the material, the greater the rate of heat transfer. In addition, the higher the temperature difference between the two materials, the more heat will be transferred. Furthermore, the larger the surface area of the material, the greater the rate of heat transfer. Recommendation This lab experiment has shown that heat transfer is a complex process and can be further explored by performing more experiments with different materials and different temperature differences. In addition, this experiment has shown that the factors which affect heat transfer, such as thermal conductivity and surface area, can be manipulated to increase or decrease the rate of heat transfer. Therefore, it is recommended that further experiments should be conducted in order to further understand how these factors interact to affect the rate of heat transfer. Additionally, it is recommended that experiments should be conducted to explore how different materials and different temperature differences affect the rate of heat transfer. Finally, it is recommended that experiments should be conducted to explore how different materials and different surface areas affect the rate of heat transfer.
How is the average rate of heat transfer calculated?
when is heat transferred?
Why do different materials heat up at different rate?
usually metals or conductors get the heat energy from the heat. the heat transfer the particles in the conductors which causes it to heat up in a faster rate to get it hot.
How the rate of heat transfer is reduced?
rate of heat transfer between two bodies can be reduced by providing insulation between the two. e.g. As in thermos flask. where the insulation prevents heat flow from liquid/tea stored inside the flask to outside atmosphere
How does temperature affect the rate of heat transfer?
For conductive and convective heat transfer, the rate of heat transfer is proportional to the the temperature difference; if you double the difference you will double the rate of heat transfer. For radiative heat transfer, the rate of heat transfer is proportional to the difference of the 4th powers of the absolute temperatures.
What is thermal conduct?
The rate at which heat flows through a material between points at different tempatures
What does an insulator do to the rate of heat transfer?
It reduces the rate of transfer.
How heat transfer rate increases in shell and tube heat exchanger?
In simple words, by increasing retention time of fluids. Other parameters which affect rate of heat transfer are: 1) Fins 2) Baffles 3) no. of passes. 4) Material of construction of tubes.

What is the heat which travel molecule to molecule?
if you mean the transfer rate of heat ?; the heat transfer rate depends on the atom or molecule type .
How is the average rate of heat transfer calculated?
when is heat transferred?
How is the rate of a cooling of a building affected by the thickness and the thermal conductivity of its walls?
Generally thicker walls slow down the transfer of heat, and if the material is a good thermal conductor that will increase the rate of transfer.
Which slavic country has the slowest rate of urbanization?
Moldova has the slowest rate of urbanization.
Does temperature difference does not affect heat transfer rate?
yes
What is thermal risistance?
It is the rate of resistance of a material to heat.
Why do different materials heat up at different rate?
usually metals or conductors get the heat energy from the heat. the heat transfer the particles in the conductors which causes it to heat up in a faster rate to get it hot.
