A gas with a volume of 2 L at 25°C is placed into a container that is 4 L. What is the new temperature of the gas?

Given :

A gas with a volume of 2 L at 25°C is placed into a container that is 4 L.

To Find :

The new temperature of the gas.

Solution :

Since, their is no information regarding pressure. We will assume that pressure is constant.

Now, we know when at constant pressure, volume is directly proportional to volume.

Therefore, the new temperature of the gas is 596 - 273 K = 323  K.

"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."
