Answer:
condensation - thermal energy removed
freezing -thermal energy removed
deposition - thermal energy removed
sublimation - thermal energy added
evaporation - thermal energy added
melting - thermal energy added
Explanation:
Thermal energy is heat energy. Processes in which heat is added involve the addition of thermal energy while processes in which heat energy is removed involves removal of thermal energy.
Condensation involves a change from gas to liquid, freezing involves a change from liquid to solid while deposition involves the settling of mobile particles at a place. All these processes involve a decrease in energy of particles.
On the other hand, sublimation is a direct change from solid to gas, melting involves a change from solid to liquid while evaporation involves a change from liquid to gas. All these processes occur when energy is added to the particles in a system.
A 1 or 2 electrons because it is the brainless answer
Answer:
Metal - smallest band gap energy
insulators - large band gap energies
semiconductor - Band gap of intermediate energies
superconductor cooper pair theory is applied for calculating gap energies.
Explanation:
Metal - smallest band gap energy
it is due to the fact that valence and conduction bond in metal are in overlapped conditioned. Therefore showing zero gap energies
insulators - large band gap energies
insulator has high band gap
semiconductor - Band gap of intermediate energies
semi conductor has gap of intermediate range
while for superconductor cooper pair theory is applied for calculating gap energies.
