What i learned

Today i learned conduction occurs when two object at different temperatures are in contact with each other.Heat flows from the warmer to the cooler object until they are both at the same temperature. Conduction is the movement of heat through a substance by the collision of molecules. In liquids and gases, convection is usually the most efficient way to transfer heat. Convection occurs when warmer areas of a liquid or gas rise to cooler areas in the liquid or gas. Both conduction and convection require matter to transfer heat.Radiation is a method of heat transfer that does not rely upon any contact between the heat source and the heated object.
