Answer:
Mass
Explanation:
Physical properties of substance are classified as Intensive property and Extensive property.
Intensive Property:
A physical property whose value is independent of the mass of a substance for which it is measured.
Examples:
i) Melting / Boiling Points
ii) Temperature
iii) Color
iv) Density
v) Pressure
Extensive Property:
A physical property whose value is dependent on the mass of a substance for which it is measured.
Examples:
i) Amount of Substance
ii) Mass
iii) Volume
iv) Enthalpy
v) Entropy
Answer:
In chemistry and physics, a valence electron is an outer shell electron that is associated with an atom, and that can participate in the formation of a chemical bond if the outer shell is not closed; in a single covalent bond, both atoms in the bond contribute one valence electron in order to form a shared pair.
Heat can be transferred from one material to another by direct touch (conduction), by differences in density of a fluid (temperature difference), and by RADIATION
