Answer 1

without an external agent doing wrok heat will always flow from a hotter to a color object . two objects of different temperature always interact . There are three different ways for heart to flow from one object to another . they are conduction convection and radiation. ...

Answer 2

Flow of heat:

The condition that is necessary for heat transfer to occur between two objects  is that two objects 'must have different temperature'.

Heat always flow or move from the hotter object to the cooler one until their temperatures are equal or temperature difference is equal to zero.

The three modes of heat transfer are:

• Conduction
• Convection
• Radiation
