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.Know More
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 about Electricity
One example of electric force in everyday life is the static electricity observed when clothes stick together after being run through the dryer. Another example is the lightning visible during a thunderstorm.Full Answer >
There are a number of natural ways to ease trapped intestinal gas, including allowing the gas to pass naturally, moving the bowels and sipping hot tea, according to About.com. Other natural remedies include exercising, using a heating pad or chewing fennel seeds.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 >
Electric trains use electricity to power electric motors, driving their wheels and providing locomotion. The electricity comes from one of three sources. It is either delivered via an electrified third rail beneath the train, via electrified cables above the train, or stored in batteries on board the train.Full Answer >
