Conduction occurs in solids and liquids but not gases.
Convection occurs in gases and liquids.
i want this answer as early as possible sum 1 please help me i m in need of this answer
Energy transfers to the air through processes such as conduction, convection, and radiation. Conduction occurs when there is direct contact between a warmer object and the air, transferring heat. Convection involves the movement of hot air rising and cool air sinking, creating a transfer of energy. Radiation is the transfer of heat through electromagnetic waves.
i do not no the answer tell me please
please tell me the difference between thickness
Please answer this question
please anyone
The difference between Saudi Arabia and Australia
Heat can transfer from object to object through conduction, where heat energy is transferred through direct contact between objects. It can also occur through convection, where heat is transferred through the movement of fluids or gases between objects. Additionally, heat transfer can happen through radiation, which involves the emission of electromagnetic waves from a warmer object to a cooler one.
unable to differentiate the difference between Business Consulting and counselling please assist
6.0 :) Rate my answer please
Do you mean "transmitted" or "exchanged" instead of "conducted"? Conduction is one of three methods of heat exchange. The other two are convection and radiation. Conduction is heat exchanged when a material directly touches a cooler material. The atoms in the hotter material vibrate against the atoms in the cooler material, causing the cooler atoms to vibrate faster and become warmer. Convection is heat exchanged when a material moves from one place to another. In a home heating system, hot air from the furnace or radiator is blown around the house, and the house is thus heated by convection. Radiation is heat exchanged by electromagnetic radiation. The Earth is heated by light (electromagnetic waves) from the Sun.
The transfer of energy from one object to another varies as the type of energy being transferred. If we consider billiards, we see the kinetic (mechanical) energy of one ball transferred to another by contact. The transfer of thermal energy can be accomplished via conduction, convection or radiation. There is more, but specific answers require specific questions. Additionally, conservation laws apply in all cases.
