What are two examples of good insulators?
Conductors are materials that will allow electricity to flow through them. Materials that contain 1, 2, or 3 valence electrons are good conductors. Some examples of good conductors are gold, silver, aluminum, and copper. Insulators are materials, or combinations of materials, with a high number of valence electrons (5, 6, 7, and 8). Examples of good insulators are porcelain, glass, air, and rubber.

What are the characteristics of ceramics?
Physical properties means the behavior of materials in response to physical forces other than mechanical, such as; Volumetric, thermal, electric and electrochemical properties. Most Ceramics are lighter than metals but heavier than polymers. Most ceramics have a higher melting point than most metals as it is that some ceramics such as China can with stand high temperatures to about 1200 degrees centigrade. Ceramics also has lower Electrical and Thermal Conductivity than most metals but the range of value is greater in ceramics permitting some ceramics to be used as insulators, for example Porcelain insulators and others as conductors like Lithium-ion conducting glass-ceramics and oxide ceramics. Thermal expansion is another physical property of ceramics, Ceramic thermal expansion coefficients are less than those of metals but effects are more damaging in ceramics bringing about cracks and other failures(Thermal shock and thermal cracking) as for ceramic materials with relatively high thermal expansion and low thermal conductivity however there is glass ceramics that has low thermal expansion thus resisting thermal shock and thermal cracking, for example Pyrex glass ceramics. Thus the physical properties being but not limited to permeability, elasticity, considerable strength, hardness, brittleness, resistance to chemical attack and thermal shock.
What makes good thermal insulators and conductors?
Good thermal insulators have high thermal resistance and low thermal conductivity, which helps to slow down heat transfer. Materials like foam, fiberglass, and wool are good insulators. Good thermal conductors, on the other hand, have high thermal conductivity and allow heat to transfer quickly. Copper, aluminum, and silver are examples of good thermal conductors.
What is the term fornmaterials that have very low thermal energy and resistance?
The term for materials that have very low thermal energy and resistance is insulators. Insulators prevent the transfer of heat and electricity due to their high electrical resistance and low thermal conductivity. Examples of insulators include rubber, glass, and plastic.
What things are thermal insulators?
some examples are coffe cups, coffe mugs styrofoam cups and coolers.
What do thermal insulators have?
Thermal insulators have insulating capabilities. This means that they do not have any aspect that allows them to conduct thermal energy.
What is the opposite of thermal insulators?
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.
What is energy that doesn't transfer thermal energy easily?
Insulators are materials that don't transfer thermal energy easily. They have low thermal conductivity, which means they resist the flow of heat, helping to keep objects warm or cool by preventing the loss or gain of thermal energy. Examples of insulators include wood, plastic, and rubber.
What is the term for materials that have very low themal energy and resistance?
The term for materials that have very low thermal energy and resistance is "thermal insulators." These materials are poor conductors of heat, making them effective at reducing the transfer of heat energy. Examples of thermal insulators include fiberglass, foam, and wool.
What kinds of materials make good insulators?
There are a number of materials that make good thermal insulators. Blankets and pockets of air make good thermal insulators for example.
What materials are thermal insulators?
A thermal insulator is a material which does not allow the passage of heat; therefore the particles which make up the material are not free to move. Plastics, wood, and air can be thermal insulators providing that NO thermal currents can develop. Air in trapped clothing, air between the panes of glass in double glazing are examples, as are a lid to cover the coffee mug.
What are 5 examples of insulators?
