Answer:
Final temperature of the gas is 576
.
Explanation:
As the amount of gas and pressure of the gas remains constant therefore in accordance with Charles's law:

where
and
are volume of gas at
and
temperature (in kelvin scale) respectively.
Here
,
and 
So
849 K = (849-273)
= 576 
So final temperature of the gas is 576
.

Answer:
A bonding that occurs between high electronegative atoms such are N, F, O and H atoms, is called a hydrogen bond. Hydrogen bond is a very strong bond. (C)
If hydrogen bonds are not formed between H atoms and N, F, O atom, then the atoms interact through dispersion forces (also known as london dispersion forces). Dispersion forces are weak and they are temporary forces formed by overlapping of orbitals. (B)
