Explain why metals are good conductor of heat?
Metals are especially good at conducting heat because they have electrons in. These are called delocalised electrons which are free moving electrons. Therefore when they gain kinetic energy (heat) they vibrate quicker and can then move around. This means that they can pass on the kinetic energy (heat) more quickly.
What processes of heat transfer are affected with thermos flasks?
Conduction, convection and heat radiation.
An increased distance of the electrons from the nucleus causes th be affected?
less, decreases
What is a group of elements with few valence electrons that conduct heat amd electricity?
halogen NOTE added by Dr.J.): A halogen doesn't have a few valence electrons. They have 7 valence electrons.
Are plastic freezer drawers better than metal?
No. Plastic is a bad conductor of heat as it does not have free electrons and metal are good conductor of heat as they have one or two free electrons in outer orbit.
Why are metals conductors of heat?
Because of their many valence electrons. The free-moving electrons transmit heat quickly.
What do heat particles do?
there is no such thing as heat particles. Electrons carry heat to and from molecules.
How are electrons involved in conducting heat or electricity?
I dont think anybody knows 2nd Answer: The movement of free electrons is the definition of electricity. Molecules (including atoms) that move about is the definition of heat. The faster they move about (Brownian Motion) the more heat can be measured. Electrons are not "conductors" of heat.
How are conduction and heat different?
Conduction is the transfer of electrons in an element while Heat is the effect caused due to the transfer of electrons .
Why metal's are good conductor of heat?
metals are densely packed molecules that transfer heat easily while less dense matter do not transfer heat easily.
Radioactive decay can be affected by what?
Most types of radioactive decay cannot be affected by anything. However, radioactive decay involving electron capture will be affected by the removal of electrons from around the nucleus. In the absence of orbital electrons, it cannot occur at all.

Therefore when they gain kinetic energy (heat) they vibrate quicker and can then move around. This means that they can pass on the kinetic energy (heat) more quickly.
Why do metals conduct heat and electricity?
Electrons in metals are mobile and carry (conduct) electricity and heat energy. Plato: Free moving electrons carry both heat and electric current throughout the system
Why are electrons affected by the addition of heat light or electricity?
Each of those has energy; so each of them MAY, under certain circumstances, knock an electron out of its orbit around the atom, or make it move around.
What happens if you heat copper?
If you heat copper it will oxidise and therefore lose electrons.
Is pewter affected by attic heat?
Probably not but in extreme heat it would. I think.
Which subatomic particle is affected by heat?
electron.
