Explanation:
Vapor pressure is defined as the pressure exerted by the vapors which are present on the surface of a liquid. Less is the intermoecular forces present within the molecules of a substance more will be its vapor pressure.
For example, is a gas and there exists Vander waal forces between its molecules. Hence, it has more vapor pressure than and .
In , there exists hydrogen bonding which is stronger than bonding present in . So, has low vapor pressure.
In , there exists dipole-dipole interaction which is stronger than Vander waal forces but weaker than hydrogen bonding.
Therefore, given compounds are arranged in decreasing order of their vapor pressure as follows.
The spring constant determines how far the spring will stretch for a given applied force: <span>F=kx→k=<span>Fx</span></span><span>. If we place the same mass on the two springs, which means we have placed the same force on them, the one that stretches </span>least<span> has the largest spring constant. Hope this helps!
