Why is diamond a good of heat like metals but a bad conductor of electricity unlike metals?
this is due to the fact that diamond has perfect lattice structure which helps it to conduct heat but due to the absence of free electrons it cannot conduct electricity.
there are two modes to conduct heat :1) thraugh free electron transfer 2) thraugh lattice vibration .in diamond lattice vibration is dominant.

What are the methods of producing emf?
Presently, there are six known methods for producing a voltage or electromotive force (emf). Some of these methods are more widely used than others, and some are used mostly for specific applications. Following is a list of the six known methods of producing a voltage. 1. FRICTION - Voltage produced by rubbing certain materials together. 2. PRESSURE (piezoelectricity) - Voltage produced by squeezing crystals of certain substances. 3. HEAT (thermoelectricity) - Voltage produced by heating the joint (junction) where two unlike metals are joined. 4. LIGHT (photoelectricity) - Voltage produced by light striking photosensitive (light sensitive) substances. 5. CHEMICAL ACTION - Voltage produced by chemical reaction in a battery cell. 6. MAGNETISM - Voltage produced in a conductor when the conductor moves through a magnetic field, or a magnetic field moves through the conductor in such a manner as to cut the magnetic lines of force of the field.
What is a form of electricity that attracts things?
It really depends on whether it is negative or positive but the simple answer is STATIC
What is resistance activities?
Active resistance is a violent way of protesting the government, unlike passive resistance, which is nonviolent.
What is the wavelength of DC current?
Unlike AC, which HAS waves, DC current is waveless- either on or off. No waves= no wave length.
The voltmeter has greater accuracy when measuring what kind of current?
A voltmeter has greater accuracy when measuring direct current. This kind of current is constant unlike alternating current which has constant fluctuations.
Is diamond the best conductor?
Diamond is not a good conductor of electricity. It is actually an insulator, meaning it does not conduct electricity well. Diamond's structure lacks free electrons needed for conducting electricity, unlike metals which are excellent conductors.
Is wood good conductor of electricity?
No, wood is not a good conductor of electricity. Unlike metals, wood is an insulator and does not allow electricity to flow easily through it. This is why wood is commonly used in electrical applications to help insulate and protect against electric shocks.
Is a wooden stick a good conductor?
No, wooden sticks are not good conductors of electricity because wood is an insulator. This means that electricity does not flow easily through it, unlike conductors such as metals.
Why is glass a bad conductor of electricity?
Glass is a bad conductor of electricity because its atomic structure lacks free-moving electrons, which are necessary for the flow of electrical current. Unlike metals, where electrons move easily through a conductive lattice, the electrons in glass are tightly bound to their atoms, making it an insulator rather than a conductor.
Why does metal conduct electricity?
metal conducts electricity because it allows electrons to move freely as well as it has free electrons, unlike insulators(non-metals) which do not have free electrons. When the electrons are allowed to move freely in a substance, it is a good conductor and allows electric charge to flow.
Why is selenium a non metal?
Selenium is a nonmetal because it lacks the physical and chemical properties of metals. It tends to gain electrons in reactions rather than losing them like metals, and it is brittle in solid form rather than malleable and ductile like metals. Additionally, selenium is a poor conductor of heat and electricity, unlike metals.
Why Papaya is bad conductor of electricity?
Papaya is a bad conductor of electricity primarily because it is composed mostly of organic materials, such as water, sugars, and fibers, which do not facilitate the flow of electric current. Unlike metals, which have free electrons that allow for easy electrical conduction, papaya lacks these conductive properties. Additionally, the high water content in papaya is not sufficient to make it a good conductor, as the dissolved ions that aid conductivity are minimal compared to that in electrolytic solutions. Thus, the overall structure and composition of papaya make it an ineffective conductor of electricity.
Why is wood not good a conductor of heat?
Unlike metals, wood and other non-conductors do not contain free electrons in their valence electron ring. These valence electrons pass on heat and electricity. Because wood doesn't have this sea of electrons, it's not as good of a conductor as metals.
Why is silicon a good heat conductor but a poor electrical conductor?
Silicon has a high thermal conductivity due to its crystalline structure which allows the movement of heat energy through the material. However, it is a poor electrical conductor because its electrons are tightly bound in the covalent bonds of the crystal lattice, making it difficult for them to move and carry an electrical current.
What is a property of a non-metal?
what is the physical property of a non-metal
What is an opposite of an insulater?
An opposite of an insulator would be a conductor, which is a material that easily allows the flow of electricity or heat. Conductors have low resistance, unlike insulators, which have high resistance.
Why are pans placed over a flame and not on the side of a flame?
Pans are placed over a flame and not on the side of the flame, because it is an energy transfer by direct contact called conduction. And as you can see, pans are usually made of metals, wherein metals are a good conductor of heat unlike wood, which is a poor conductor of heat.
