thermal expansion
cold objects do have heat energy.
its temperature is increased and if temperature supplied continously phase change can be changed
heat dosent travel from cold objects to hot objects ,it only travels fron hot to cold objects
When objects touch, heat is transferred by the process of conduction. Conduction is when heat transfers when molecules collide!

No. Heat is not affected by gravity. Heat flows from hotter objects to colder objects.

Heat always flows from warmer objects to cooler objects.

white objects reflect heat while black objects absorb it
Heat always flows from warmer objects to cooler objects, unless you have a device (like a heat pump) to prevent this. The natural tendency is for two or more objects at different temperatures to eventually all have the same temperature and this is accomplished by heat flowing from the warmer objects to the cooler objects.
When objects touch, heat is transferred by the process of conduction. Conduction is when heat transfers when molecules collide!
In this case, no heat will flow between the objects. At least, there will be no "net" heat flow. The objects are said to be in thermal equilibrium, so that any heat exchanged by their molecules is balanced and there is no net change in temperature.
Heat moves from warmer objects to cooler objects.
silver absorbs heat just like black objects.
