Hello,
The process of heat transfer in solids is primarily called conduction. It's a fascinating phenomenon where thermal energy moves through a material without the material itself moving.
Here's how it works:
Imagine a solid material, like a metal rod. When you heat one end of the metal rod, the atoms at that end gain more energy and vibrate more vigorously. These energetic atoms collide with their neighboring atoms, transferring some of their kinetic energy. This process is similar to chain reaction, where the energetic atoms pass their energy to the next atoms. As this happens, the increased vibrations spread throughout the solid, and the thermal energy gradually transferred from hotter region to the cooler region. This is called Conduction process.
The efficiency of conduction depends on material's ability to conduct heat.
Materials with high thermal conductivity are called excellent conductors of heat .
example: Copper, Silver, Gold etc.
Materials with low thermal conductivity are called poor conductors are often used as insulators.
example: wood, plastic air etc.
I hope this answer helps you!
The process of heat transfer in solids is primarily called conduction.
Conduction is the transfer of thermal energy from one part of a substance to another part of the same substance, or from one substance to another in physical contact, without any visible movement of the material itself.
Dear student,
Hear is a form of energy which can travel, it might need a medium or it might not.
When it does not require a medium, that is travel through vacuum, the transfer is called - RADIATION.
However, When it does require a medium to travel through then it can happen in two ways-
1. The medium could be a FLUID: The process of heat transfer here is called convection, where there is a cyclic flow of heat, imagine a vessel of water heating.
2. The medium could be a SOLID: The process of heat transfer here is called CONDUCTION, where there is a vibration among the molecules carrying the energy to newer molecules and ultimately transferring the heat away from source.
Question : Which of the following options correctly explains the term heat budget?
Option 1: It is a mode of transfer of heat through matter by molecular activity
Option 2: It is the balance between incoming and outgoing radiation
Option 3: It is the radiation from the earth in the from of long waves
Option 4: It is the amount of heat which the surface of eatrh receives from the sun
Question : Heat stored in water vapour is:
Option 1: Specific heat
Option 2: Latent heat
Option 3: Absolute heat
Option 4: Relative heat
Question : When quick lime is added to water
Option 1: Heat is liberated
Option 2: Heat is absorbed
Option 3: Temperature decreases
Option 4: No heat change takes place
