What form of heat transfer is the most common to strike the Earth from space?

Radiation is the transfer of heat energy through space by electromagnetic radiation. Most of the electromagnetic radiation that comes to the earth from the sun is invisible.

What is needed for heat to transfer from one object to another the two object should?

What is needed for heat transfer to take place is a difference in temperature between two objects. Without this difference, no heat transfer can take place. Heat can be transferred in three ways: by conduction, by convection, and by radiation.

Which action can transfer the greatest amount of heat?

Conduction is the most significant form of heat transfer within a solid object or between solids in thermal contact. Conduction is most significant in solids, and less though in liquids and gases, due to the space between molecules.

What is the needed for heat to transfer from one object to another?

This then continues and passes the energy from the hot end down to the colder end of the substance. Thermal energy is transferred from hot places to cold places by convection. Convection occurs when warmer areas of a liquid or gas rise to cooler areas in the liquid or gas.

What happens when heat is absorbed by an object?

When absorbed by a substance, heat causes inter-particle bonds to weaken and break which leads to a change of state (solid to liquid for example). There is no increase in the particle motion and hence no rise in temperature. THERMAL ENERGY is one type of INTERNAL ENERGY possessed by an object.

What type of heat transfer is warming your hands by a fire?

Thermal radiation
Thermal energy radiates from a fire and warms a persons hands. Thermal radiation is one of three ways that thermal energy can be transferred. The other two ways are conduction and convection, both of which need matter to transfer energy.
