Something that transfers thermal energy efficiently is called a conductor.
A good thermal conductor is something that transfers thermal energy efficiently. Materials like metals, such as copper and aluminum, are known for their ability to conduct heat effectively.
A material that transfers thermal energy efficiently is called a conductor. Conductors have high thermal conductivity, allowing heat to pass through them easily. This property is why materials like metal are often used in cooking pots and electrical wires.
You're probably fishing for "conductor".
An insulator
The term for something that does not transfer thermal energy efficiently is "insulator." Insulators have low thermal conductivity and prevent the flow of heat from one area to another. Materials like wood, plastic, and rubber are commonly used as insulators.
An insulator is a material that does not transfer thermal energy efficiently. It prevents heat from flowing easily through it, helping to maintain a consistent temperature on either side. Some common examples include foam, wool, and fiberglass.

Thermal energy poorly and slowly transfers in liquids
Argon gas has low electrical conductivity, as it is classified as a non-metal gas. However, it has good thermal conductivity, which means it efficiently transfers heat.
Glass is a better insulator of heat compared to clay. Clay transfers heat more efficiently due to its higher thermal conductivity.
Materials that transfer thermal energy easily are called "good conductors." These materials have a high thermal conductivity and allow heat to flow through them quickly and efficiently. Metals such as copper and aluminum are examples of good conductors of heat.
