Heat measures the movement of molecules in an object, while temperature measures the average energy or heat generated by the molecules in an object. The faster the molecules move, the more heat they produce and the higher their temperatures become.Know More
Molecules are clusters of atoms, which are always in motion. As they bump and slide into each other, they vibrate back and forth and this motion produces heat. Many types of energy are converted into heat, including electrical, mechanical and chemical energy. Electrical energy occurs when you use a heating pad, a toaster or a light bulb. Mechanical heat, for example, is produced when a ball is bounced on the floor. The ball slows with each bounce because some of the motion of the ball's bouncing heats up its surface. Chemical heating occurs when your body uses food as fuel to warm you up.
Temperature determination depends on the size and density of the object being heated. A large object has a lower temperature than a small one, because the kinetic energy or movement within the smaller object is more concentrated and there is less room for it to disperse. Therefore, these molecules just vibrate, which causes more friction and raises the temperature of the object.Learn more about Thermodynamics
The addition of heat raises the temperature of a material by a certain amount. The amount of heat needed to raise the temperature of a unit mass or volume of material by one degree is called the specific heat of the material.Full Answer >
The thermocouple works by converting the heat generated from the pilot light on a furnace into an electrical signal that tells the gas valve whether to open or close. The thermocouple is technically known as a thermocouple junction. It is an electronic device.Full Answer >
In order for a substance to melt, it must absorb enough energy to overcome the intermolecular bonds holding its molecules together. These bonds may be ionic, molecular, covalent or metallic, depending on the material involved. Ionic bonds require the most energy to overcome, while molecular bonds are easier to break.Full Answer >
According to Elmhurst College, the molecules in a liquid are packed closely together and make random movements, as the molecules slip past each other. As the liquid is heated, the kinetic energy increases, which causes the motion of the molecules to increase. Eventually, the motion becomes so intense that the forces of attraction between the molecules are disrupted, and the molecules break free of the liquid, becoming a gas.Full Answer >
