Heat transfer takes place whenever there is a temperature difference between two objects or systems. This can occur through conduction (direct contact), convection (through a fluid or gas), or radiation (through electromagnetic waves). Heat transfer is a fundamental process in nature that aims to equalize temperature differences.
Conduction, which is the transfer of heat through direct contact between particles, cannot take place in a vacuum because there are no particles present to transfer the heat.
Conduction takes place in the process of heat transfer through direct contact between objects or substances.
Heat transfer can take place in any container that can conduct heat, such as metal pots and pans, glass containers, and ceramic dishes. The material of the container will influence how quickly heat is transferred to or from the contents inside.
Conduction cannot take place in liquids because the particles are free to move around, disrupting the transfer of heat. In solids, particles are closely packed and transfer heat through vibrating in place, allowing conduction to occur easily.
The type of energy transfer that can take place with little or no matter present is radiation.
Wrong, transfer of heat by conduction does take place in fluids.
Conduction, which is the transfer of heat through direct contact between particles, cannot take place in a vacuum because there are no particles present to transfer the heat.
In all circumstances where a material is hotter than its surroundings, heat transfer takes place.
Wrong, transfer of heat does take place in fluids. In fact it can take place more efficiently in fluids than in solids because convection is possible in fluids.
Conduction takes place in the process of heat transfer through direct contact between objects or substances.
convection
It is the process of transfer of heat from one place to other with actual movement of heated particles. Convention of heat take place in fluids and gases .
Convection
Heat transfer can take place in any container that can conduct heat, such as metal pots and pans, glass containers, and ceramic dishes. The material of the container will influence how quickly heat is transferred to or from the contents inside.

The type of energy transfer that can take place with little or no matter present is radiation.
This is known as convection heat transfer. As particles in a heated substance rise, they carry heat energy with them, causing cooler particles to move in to take their place. This circulation creates a transfer of heat throughout the substance.
