Heat is an energy that can be transferred just like sound, light, and electrical currents. We use heat in our everyday lives to cook food or warm our houses. Heat travels from warm objects to cold objects. This happens because the molecules hit each other, and the faster-moving molecules in the hot object spread that energy into the cooler object.

Heat is a form of energy that we can feel. Heat is the transfer of thermal energy through vibrations between molecules. As the temperature of an object of substance increases, its molecules will begin to vibrate more quickly. Thermal energy is the movement of molecules that make up an object or substance.

Thermal energy is another term for heat energy. Thermal or heat energy is generated when molecules rub against one another, causing friction. The faster the molecules move, the more heat energy is created. To measure how much thermal energy something has, we take its temperature with a thermometer.

Three of the items listed are insulators: wood, styrofoam, and plastic, but only one of them will not melt with the heat of the fire. Wood is the best option to keep their hands from burning and the device from melting. Metal is a conductor, so this device would get very hot and transfer heat to the boy's hands.

The three ways heat can be moved or transferred are through conduction, radiation, and convection. Conduction is heat transfer between two objects that are touching. Radiation is the heat transfer through air or space by electromagnetic waves. Convection is heat transfer by a current of water or air.

Metal is the best conductor of heat because its atoms are arranged in a way that allows electrons to travel freely, meaning they can pass energy more quickly.

Temperature is the mode by which we express hot and cold. We most commonly do so using measurements in either Fahrenheit or Celsius. Temperature is a manifestation of thermal energy and can be measured using a thermometer.

Insulators are materials that do not allow heat to escape or be conducted away. Examples of insulators are down clothing, fiberglass, or plastic.

Insulators are materials that do not allow heat to escape or be conducted away. Because the arctic fox lives in a harsh, cold environment, its fur is there to help keep it warm. Most animals that live in frigid environments have a layer of fur to act as an insulator.

Metal is a good conductor of heat because energy passes through it quickly. When a pan is put on a hot stove, the particles closest to the burner begin to move more rapidly. They bump into the slower-moving particles, which causes the heat to spread. In this photo, the metal pan is acting as a conductor to spread the heat coming from the burner.
