That depends A LOT on the type of energy. For example, light energy will pass through transparent substances, such as glass; electrical energy (in the form of a current) will pass through conductors, especially metals, etc.
That really depends on the type of energy. For example, an electrical conductor allows electrical currents to pass, while an optic fiber (or more generally, any transparent substance) allows light to pass. Some substances let heat through better than others, some let sound through better than others, etc.
Medium
transparent
Water
No. A light switch merely allows energy to pass, or not to pass.
conductor of heat and electricity
Heat conductors allow heat energy to pass through; heat insulators do not.
allows a cell to control what substances pass into and out of it?
transparent
Water
An electrolite
No. A light switch merely allows energy to pass, or not to pass.
conductor of heat and electricity
Heat conductors allow heat energy to pass through; heat insulators do not.
a substance which has a low resistivity and allows a large amount of current to pass through
Insulator is a substance that does not allow heat to pass through it example air. conductor is a substance that allows heat to pass through it example metal.
electron
capillaries
Conduction is where heat energy pass though the molecules by direct contact
