La diástole es aquella durante la cual el músculo cardíaco se relaja y se llena de sangre, mientras que la sístole es un período de contracción y bombeo de sangre. La diástole ventricular es el momento en el que las dos cámaras inferiores del corazón conocidas como ventrículos se relajan para permitir que la sangre fluya hacia adentro.

A friend asks you how to determine the strongest intermolecular force present in a pure sample. Write down for them the steps yo
LenaWriter [7]

The best method used to determine the strongest intermolecular forces is to check it's it boiling or melting point.

Explanation:

So, when the molecules are polarized, the charges on the atom becomes greater which would lead to a greater intermolecular force. hence, those components will have a high boiling point. Here is the ascending of atomic bonds which would help us to determine what bonding so we could say whether it is the strongest or not.

Ionic bonds>Hydrogen bonding>Van der Waals dipole interaction>Van der Waals dispersion forces

So, you have to heat or melt the pure sample to determine the strongest intermolecular force depends on the components in the sample.
