Question

does transfer of heat takes place in all situations?

Answer 1

Heat transfers from one place to another in all physical conditions and in some  chemical  conditions

Heat Transfers through three process---
                      Conduction -- Convection -- Radiation

Answer 2

We need to answer whether the transfer of heat takes place in all situations            

•  Transfer of heat can take place in all situations
• In solids heat transfers through conduction
• In liquids and gases heat transfers through convection
• In a situation where there are no particles to move and transfer heat, the transfer takes place through radiation
• Although radiation can take place in all situations conduction and convection cannot take place in a vacuum
