Can a cold spoon transfer heat?
No. Heat can only be transferred to a cold spoon, not the other way round (as there is no heat in a cold spoon to transfer). A simple example is when a cold teaspoon is used to stir a hot cup of tea. When the spoon is withdrawn, it is hot.
What is the directinality of heat transfer?
From "hot" to "cold".
What method of heat transfer prevents cold draughts?
Insulation
Does heat transfer mean the same as heat transformation?
heat transfer is when heat from one object transfers to another. Heat transformation is when you have enough heat or cold to change the state of an object (ice to water).
What will happen when a cold material interacts with a hot material?
The heat will transfer from the hot material to the cold material. Heat tends to go where it is not.
When you dip your hand in cold water you feel it cold. Can you name the mode of heat transfer and its direction?
This type of heat transfer is called conduction. The transfer is from the warm hand to cool water.
What is hot to cold?
hot to cold is heat transfer

Why carnot cycle is called a two adiabatic and two isothermal process?
Adiabatic means there's no heat transference during the process; Isothermal means the process occurs at constant temperature. The compression and expansion processes are adiabatic, whereas the heat transfer from the hot reservoir and to the cold reservoir are isothermal. Those are the two adiabatic and isothermal processes.

How does energy from heat transfer from a hot source to a cold source?
Convection
Which two methods of heat transfer are possible with liquids which of the two has greater effect?
The two methods of heat transfer that are possible with liquids are convection and conduction. Convection has a greater effect because it helps heat spread faster.
Which way does heat transfer?
Heat always flows from a hotter object to a colder one. So: Heat 'transfers' from 'hot' to 'cold' (cold being a relative term and considered an absence of heat).
