Which of the following will result from increasing the temperature of a gas?
O
A. The number of gas molecules will increase.
O
B. The molecules will be forced into a smaller space together.
O
C. The molecules will slow down.
O
D. The volume of the gas will increase.

The correct answer is D) The volume of the gas will increase.

Explanation:

According to Charles's Law, at constant pressure, as the temperature (T) of a gas increases, the volume (V) increases and vice versa. This is observed according to the formula:

V1 / T1 = V2 / T2

"among the transition metal elements, manganese and zinc have a slight lowering of electronegativities. the reason behind this is that the nuclear charges of these elements are slightly weaker than the other transition metal elements due to the way their valence electrons are filled up. both manganese and zinc have their valence electrons filled up to the 4th shell with 1 pair of electrons (4s2) completely occupying it. although the electrons in the 3rd shell (3d) are yet to be paired since the outer most shell is filled up, the ability of the nucleus to attract electrons is lessened. hence,   the electronegativity (or the ability to attract electrons) is lessened."
