Answer:
When a gas is heated, the molecules move faster, bump into each other, and spread apart. Because the molecules are spread apart, they take up more space. They are less dense.
The polarity of a bond between two elements can be best determined by difference in the values of electronegativity.
<h3>Determination of polarity of bond</h3>
The polarity of a covalent bond can be determined by determining the difference in electronegativity between the two bonded atoms. Electronegativity is defined as the tendency of an atom to attract electrons to itself.
So we can conclude that the polarity of a bond between two elements can be best determined by difference in the values of electronegativity.

Answer:
Air temperature is measure by how hot or cold is air
Explanation:
Molar mass of Cu = 63.5g/mol
Moles of Cu
= 5.8g / (63.5g/mol) = 0.091mol (B)
