Zero, cause the positive and negative work cancel out :)
Answer:
fossil fuels are natural and limited, nuclear is man made and more toxic
Explanation:
<h2>Answer:</h2>
Low melting points and electrical conductivity in solids are not common properties of ionic solids.
<h3>Explanation:</h3>
In ionic compounds the electrons involved in the bonding are tightly packed under the influence of electrostatic force of attraction. So the movement of these electrons is very difficult.
In the melting point the bond breaking between the atoms is involved. Hence in case of ionic compound there is a high amount of energy needed to break the ionic bonds.
Electrical conductivity involves the free movement of electrons which is impossible in ionic solids.
So low melting points and electrical conductivity in solids are not common properties of ionic solids.
Answer:
The Kelvin temperature scale is used by scientists because they wanted a temperature scale where zero reflects the complete absence of thermal energy. ... Many quantum mechanical properties are washed out by the thermal agitation that occurs in materials.
