Only the free valence electrons forming the electron "gas" move and as many move in as move out. Only metals form this electron "gas".

What is thermal stability?
The decay rates of organic materials increase with temperature. Materials with a greater thermal stability will remain unchanged for a longer time.
What would happen to the voltage when the resistors are ten time larger than have be given?
If all the resistors in a circuit are changed by the same amount, including internal resistances of voltage and current sources, the voltages throughout the circuit remain unchanged. The currents will change though.If the internal resistances of voltage and current sources remain unchanged it is more complicated and will have to be computed on a case by case basis.
What happems when frequency is changed and voltage and current remain unchanged?
In magnetic circuits, such as occur in transformers and motors, the flux density is inversely proportional to the frequency, so a drop in frequency could cause overheating through excessive flux density.
Where garbage is disposed of by being buried under a shallow layer of soil?
This is called landfill. The organic garbage decomposes and methane escapes into the atmosphere. Glass, plastic and metals remain there for hundreds of years.
In a thermodynamic system if you reduce the model by half what variables would also be reduced by half?
All quantitative variables will be reduced including: Internal energy Enthalpy Gibbs energy Volume Mass Moles All intensive properties will remain unchanged including: Specific internal energy Specific enthalpy Specific Gibbs energy Specific volume (and its reciprocal density) Temperature Pressure Heat capacity Elasticity Conductivity etc.
How do ionic compounds conduct?
Do_ionic_compounds_conduct_electricitycompounds conduct electricity when they are either dissolved in water of they are molten. If they remain a solid then they will not conduct electricity
Do metal objects get charged by conduction?
When metal objects conduct electricity the electricity just passes through them, it does not remain to impart an electrical charge.
When a gas or liquid is heated then its mass is?
The mass remain unchanged.
How did the south remain unchanged after the civil war?
the south can be racist.
What will happen if there is no physical and chemical change?
The system remain unchanged.
When water evaporates does its mass decrease?
The mass remain unchanged.
Does temperature remain unchanged during vaporisation of a liquid?
yes
What colour do NaCl impart on heating?
The color remain unchanged.
When water evaporates does its mass increase?
The mass remain unchanged.
Explain why one allotrope can conduct electricity?
In one allotrope electrons remain free as charge conductors. In another they may be involved in bonding atoms.
Why low pressure gas is used in thermionic valve?
If gas particles remain, they will get ionized and conduct electricity between elements resulting in a purple glow.
Can a species remain unchanged for hundreds of thousands of years according to evolution?
In theory, they can remain unchanged for their entire existence. However, in practise, nature isn't so nice and evolution happens eventually.
