explain conduction in soil substance
Answers
Answer: mark me brainlist if it helps
During conduction, heat is transferred through the vibration of molecules in a substance. As something gets warmer, it begins to increase the vibration and movement of the molecules that it consists of. In solids, particles are closely packed together and are in direct contact.
Explanation:
Since they are close to each other, particles that vibrate near the point of contact will pass on the vibrations to other particles nearby. The vibrations then spread throughout the object. Conduction works similarly with liquids and gases, but since the density of the particles is less, there will be less efficient energy transfer between the molecules. Conduction occurs when two things at different temperatures touch each other and energy directly transfers from the material in the hotter object to the material in the colder object at the point of contact.
Answer:
The thermal properties of soil are a component of soil physics that has found important uses in engineering, climatology and agriculture. These properties influence how energy is partitioned in the soil profile. While related to soil temperature, it is more accurately associated with the transfer of energy (mostly in the form of heat) throughout the soil, by radiation, conduction and convection.
The main soil thermal properties are:
Volumetric heat capacity, SI Units: J∙m−3∙K−1
Thermal conductivity, SI Units: W∙m−1∙K−1
Thermal diffusivity, SI Units: m2∙s−1
