Question

What is mean by comuction? Explain with the help of an example why is it that conve cation cannot take place in solide?​

Answer 1

Answer:

please support me and follow me

Explanation:

Convection occurs when particles with a lot of heat energy in a liquid or gas move and take the place of particles with less heat energy. Liquids and gases expand when they are heated. ... Convection cannot happen in a solid because, like the bricks in a wall, the atoms in a solid cannot move far from where they are.mark it as a brainliest answer

Answer 2

Answer:

THERE IS NOTHING LIKE COMUCTION, IT'S CONDUCTION AND CONVECTION.

Explanation:

CONDUCTION , CONVECTION AND RADIATION ARE THE THREE (3) MODES OF HEAT TRANSFER:-

CONDUCTION-

• CONDITION IS THE TRANSFER OF HEAT IN WHICH THE HOTTER PART OF MATERIAL TO IT'S COLDER PART ( OR FROM HOT MATERIAL FROM COLD MATERIAL IN CONTACT WITH IT) WITHOUT THE MOVEMENT OF MATERIAL AS A WHOLE.
• IN SOLIDS, CONDUCTION TAKES PLACE. THIS CAN BE EXPLAINED AS FOLLOWS:-

1. SOLIDS ARE PACKED VERY CLOSELY.
2. DURING CONDUCTION, HEAT IS TRANSFERRED FROM HOTTER TO COOLER END.
3. IT MEANS FROM BACK TO FORTH, VIBRATION OF PARTICLES TAKES PLACE.

CONVENTION-

• CONVENTION IS THE PROCESS IN WHICH, THE TRANSFER OF HEAT FROM HOTTER PARTS OF A LIQUID OR GASES (FLUIDS).

NOW, LET'S ANSWER WHY CONVECTION CAN NOT TAKE PLACE IN SOLIDS:-

• THE TRANSFER OF HEAT BY CONVECTION CANNOT TAKES PLACE IN SOLIDS BECAUSE THE PARTICLES IN LIQUIDS AND GASES CAN MOVE FREELY.
• THE CONVECTION CANNOT TAKE PLACE IN SOLIDS BECAUSE THE PARTICLES IN THE SOLIDS ARE FIXED AT A PLACE AND CANNOT MOVE FREELY.
