Answer:
1.The difference in temperature of the bodies determines the direction of flow of heat. Heat flows from a body at higher temperature to one at a lower temperature.
2.conduction
4.Solids conduct heat better than liquids, which are in turn better conductors than gases. ... Thus liquids are usually poor conductors of heat. In a gas, the particles are far apart, making energy transfer by collision very inefficient.
