Which of the Following is a Poor Conductor of Heat?
A poor conductor of heat is a material that does not allow heat to flow easily through it. This means that the material will not absorb or release heat easily, and will therefore stay at a relatively constant temperature. Some examples of poor conductors of heat are glass, plastic, and wood.
There are a few materials that make poor conductors of heat. These include rubber, plastic, wood, air, and water. Each of these materials has different properties that make them bad at conducting heat.
For example, rubber is an insulator, meaning it does not allow heat to pass through it easily. This makes it good for things like tires and gloves, but not so great for cooking pots and pans. Plastic is also an insulator, but it is also a poor conductor because it is a very light material.
Wood is also a poor conductor because it is full of tiny air pockets that prevent heat from moving through it easily. Finally, water is a poor conductor because it takes a lot of energy to change its temperature.
So which one of these materials would be the best choice for keeping your food hot?
Probably not water! And definitely not rubber or plastic. Wood might seem like a good choice since it’s such a dense material, but remember that those tiny air pockets will actually work against you here.
That leaves us with air as the best choice for keeping food hot. But what if you’re trying to keep your food cold? In that case, water would be the best choice since it takes so much energy to change its temperature.

Which are Poor Conductors of Heat?
There are a variety of materials that make poor conductors of heat. These include plastics, glass, air and wood. Metals are generally good conductors of heat, but there are some exceptions including mercury and lead.
Water is also a good conductor of heat.
Which of the Following is a Poor Conductor?
There are a few materials that are considered to be poor conductors. These include things like air, glass, and rubber. While they may not be the best at conducting electricity, they can still serve as insulators to protect against electrical shocks.
What are 5 Bad Heat Conductors?
There are five bad heat conductors: water, air, glass, wood and metal. Each of these materials has a low thermal conductivity, meaning that they do not transfer heat well. This makes them poor choices for applications where heat needs to be transferred quickly, such as in cooking or heating.
Which is the Poor Conductor of Heat Class 7?
There are many materials that make poor conductors of heat, meaning they don’t transfer heat well. Some examples include air, Styrofoam, and wood. These materials are often used in insulation because they help to keep things cool.
Metals are generally good conductors of heat, which is why metal pans are often used for cooking.
2.7 Good and poor conductors of heat
Which of the Following is a Poor Conductor of Heat Quizlet
One of the most important properties of a material is its thermal conductivity, which is a measure of how well it conducts heat. The thermal conductivity of a material depends on many factors, including its composition, structure, and impurities. Some materials are goodconductors of heat, while others are poorconductors.
In this quiz, we’ll test your knowledge of which materials are good or poorconductors of heat.
Conclusion
There are a variety of materials that can be used as thermal conductors, but not all materials are equally effective. Some materials, like aluminum and copper, are excellent thermal conductors while others, like rubber and glass, are poor thermal conductors. The ability of a material to conduct heat is determined by its thermal conductivity, which is a measure of how quickly heat flows through the material.
In general, materials with high thermal conductivity are better able to transfer heat than those with low thermalconductivity. This property is important in many applications where heat needs to be transferred quickly and efficiently, such as in cooling systems and electronic devices.
