What will molecules do at -272 degrees celsius

Molecules will be very calm at - 272 °C.

According to the temperature scale, the least temperature that we can ever achieve in our practical life is - 273°C. This is the temperature from where our kelvin scale of temperature or absolute temperature starts.

The temperature of a substance is the practical manifestation of the internal energy of the substance. And this internal energy is actually reserved in form of molecular vibrations of the substance. With increasing heat, the temperature of the substance increase because of the increase in molecular vibrations of the substance. With decrease in temperature, the vibrations lessen untill - 273°C or 0K where they become completely still. So cooling beyond that point isn't possible. So at - 272°C or 1K, the molecules will be very lightly vibrating and they will have the least possible internal energy.

vanderwaal's forces of attraction are the electrostatic intermolecular forces that exist in a molecule due to the temporary or permanent dipoles that are developed in a molecule. in , the major intermolecular forces are dipole-dipole interactions as the molecule is polar (bent structure). so the vanderwaal's forces of interaction in between molecules are the permanent dipole-dipole interactions that develop due to the dipole that exists in between the polar h - s bond. the positively charged hydrogen atom is attracted towards the negative end of the dipole that is sulfur of the adjacent molecule. therefore, these forces of attraction are relatively stronger than that of london dispersion forces that exist in non polar molecules.

i believe that it is a exoplanet
