What pressure must be applied to a given sample of a gas in order to compress it to a 2/5 of its original volume at same temperature?

Posted by Gori Jain 4 weeks ago

CBSE > Class 11 > Chemistry

1 answers

Adithya Dev A 3 weeks, 1 day ago

As per Boyle's law of chemical behaviour, at a constant T, P ~ 1/V. Therefore, to compress it to 2/5 th the volume, pressure required would be [ 1/(2/5) = 5/2 ] times the original pressure.

bond = Formed by lateral or side wise overlapping of atomic orbitals such that direction of overlap lies perpendicular to the axis σ bond = Formed by axial overlapping or end to end overlapping of atomic orbitals, along internuclear axis. It is more of stronger.

Adithya Dev A 1 month, 1 week ago

σ bond = Formed by axial overlapping or end to end overlapping of atomic orbitals, along internuclear axis. It is more of stronger. There is proper distribution of electron density across the internuclear axis. Present mostly as SINGLE bonds between atoms. π bond = Formed by lateral or side wise overlapping of atomic orbitals such that direction of overlap lies perpendicular to the axis. It is more weaker than σ bonds. They are usually present as multiple bonds alongside single bonds. Electron density is distributed in an unorganized manner.
