Shiny elements are good conductors of thermal energy and electric current because their surface is smooth, allowing for efficient transfer of energy and current. The shiny surface helps reduce heat and energy resistance, making them ideal for applications where heat transfer and conductivity are important.

Silver is a shiny element that is a good conductor of both thermal energy and electric current. It has the highest electrical conductivity of any metal, making it highly effective for conducting electricity. Additionally, silver also has a high thermal conductivity, allowing it to efficiently transfer heat.
Yes, this is mostly true. It starts to become untrue near silicon.
False. Nonmetals are poor conductors of heat and electricity compared to metals. This is because nonmetals have fewer free electrons available to carry an electric current or transfer thermal energy.
Thermal conductivity is a measure of an element's ability to conduct heat. Elements with high thermal conductivity, such as metals like copper and aluminum, are good conductors of heat and can transfer heat efficiently. Conversely, elements with low thermal conductivity, such as gases like air, are poor conductors of heat and transfer heat less efficiently.
Electrical energy is converted into thermal energy through the process of resistance heating. This occurs when an electric current flows through a material with resistance, such as a heating element in a toaster or an electric stove. The resistance causes the material to heat up and emit thermal energy in the form of heat.

The shiny element most likely refers to metal, such as copper, silver, or aluminum. These metals are excellent conductors of both thermal energy and electric current due to their free electrons that can move easily through the material, carrying energy and charge with them. This property makes them widely used in various applications, including wiring, electrical components, and heat sinks.
The opposite of thermal insulators are thermal conductors. Thermal conductors are materials that allow heat to transfer easily through them, while thermal insulators are materials that block the transfer of heat.
Thermal conductors and electrical conductors both involve the flow of energy, but they are not necessarily the same materials. Some materials, like metals, are both good thermal and electrical conductors due to their free electrons that allow them to transfer energy efficiently. However, there are also materials that are good thermal conductors but poor electrical conductors, such as ceramics.
