Metals are good conductors heat and electricity true or false?
True. Metals are good conductors of heat and electricity due to the presence of free-moving electrons that can transfer energy efficiently. This property makes metals essential in various applications, such as electrical wiring and heat exchangers.
Metals react with water violently Is this a physical or a chemical property?
it is a chemical property
Which property is associated with metals dull shiny brittle or poor conductor of electricity?
Metals are associated with being shiny and good conductors of electricity. They are typically not dull, brittle, or poor conductors of electricity.
What property in metals makes them good conductors of thermal energy?
Metals are good conductors of thermal energy primarily due to the presence of free electrons, which are loosely bound to their atoms. These delocalized electrons can move freely throughout the metal lattice, allowing them to transfer kinetic energy quickly from hot regions to cooler ones. Additionally, the closely packed arrangement of metal atoms facilitates efficient energy transfer through vibrations. This combination of free electron movement and atomic interactions enables metals to conduct heat effectively.
Is poor heat conductivity a property of metal or non metal?
Poor heat conductivity is a property typically associated with non-metals. Metals are generally good conductors of heat due to the presence of free electrons that facilitate energy transfer. In contrast, non-metals, which lack these free electrons, tend to have lower thermal conductivity and are often used as insulators.
What chemical conducts heat?
there are alot of chemical mixtures that create exothermic REACTIONS, but no chemical in particular. my favorite chemical reaction is thermite. (alluminum powder, iron(ii) oxide) temperatures reach 9000 degrees!
Metals are good conductors heat and electricity true or false?
True. Metals are good conductors of heat and electricity due to the presence of free-moving electrons that can transfer energy efficiently. This property makes metals essential in various applications, such as electrical wiring and heat exchangers.
The ability for metals to rust is a physical property of metals?
Actually, rusting is a chemical reaction that occurs on the surface of metals when they come into contact with oxygen and moisture. It is not a physical property of metals, but rather a chemical property related to their reactivity with oxygen.
What property of metals make them good conductors of heat?
their mobile electrons
Corrosion is a physical property of metals?
No, corrosion is a chemical change of the metal involved.
What material in which thermal energy moves quickly?
These are good conductors-most metals are good conductors.
Metals react with water violently Is this a physical or a chemical property?
it is a chemical property
Which property of metals make them good conductors of heat?
Their mobile electrons
What is a good conduction?
Metals are good conductors of both heat and energy.
What is good conductions?
Metals are good conductors of both heat and energy.
Are metals good or bad conductors?
using the energy band model, i would rank metals as good conductors. The energy gap in metals is negligible, that is the valence band and the conduction band overlap. Thus it is very easy for electrons in the valence band to move to the conduction band thereby conducting currents. Hence metals are good conductors.
What is a property of a good conductor of electricity?
metals like copper and aluminium are good conductors of electricity.
