Some examples of conduction are a pot on a hot burner, a spoon in hot tea and touching a hot cup of coffee. In each of these examples, there is a transfer of heat from the hotter object to the colder one. Heat transfer occurs when there is molecular agitation and energy flow from an object at a higher temperature.
Some other examples of conduction are using a heating blanket to keep warm, a finger getting burned after touching a hot stove and placing a hot poker iron into water. Different materials are better heat conductors than others. For example, most metals are good conductors of heat.
However, the three types of heat transfer are conduction, convection and radiation. While convection is the heat transfer that occurs by the movement of a heated medium, such as air or water, radiation is the transfer of energy by electromagnetic waves through space. Some examples of convection are a greenhouse, the rising air in the atmosphere and an electric heater that warms up a cold room. Examples of radiation are the sun's rays, heat from light bulb filaments and using a solar oven to cook food.
Radiation differs from conduction and convection because its heat transfer involves electromagnetic waves. In conduction and convection, the transfer of heat occurs through the movement of particles.Learn More
A bistable gate is an example of a sequential logic circuit. These circuits depend on current input signals as well as a stored history of input signals that have been used in the past in order to determine output.Full Answer >
Sugar dissolves more quickly in hot tea than in iced tea because the solubility of solutes in solvents generally increases with an increase in temperature, according to Rutgers University. The heat provides energy to break the molecular bonds in the solid, causing it to dissolve faster.Full Answer >
Conduction is heat transfer through solid objects, while convection is heat transfer through liquid or gasses. Conduction and convection are both forms of radiation, which is heat transfer.Full Answer >
Heat conduction is the transfer of internal energy (microscopic kinetic and potential energy) from a region of higher temperature to one of lower temperature by the interaction of particles like atoms, molecules, ions or electrons in the intervening space. Conduction can only take place within an object or material or between two objects that are in direct or indirect contact with each other.Full Answer >
