Math

After an atom or molecule absorbs a certain amount of energy, the electron is excited to a higher energy level but not yet ionized. Excited states generally refer to electronic excited states. The translational energy of molecules increases when gases are heated, and the vibrational energy of molecules increases when liquids and solids are heated, but no electrons are excited. These states are not excited states. When an atom or molecule is in an excited state, the distribution of the electron cloud will undergo certain changes, the equilibrium distance between the nuclei of the molecule increases slightly, and the chemical reaction activity increases.

I am aware of the international online media about the covid-19 circus, and there is a new expression called hespress, I would like to find out what does that mean exactly. All this coronavirus misery upsets me 'cause before the worldwide pandamic I could find interesting and informative articles about international economy, banking, politics etc. Now all you can read about is covid and how many have died, how many have been in hospitals. It is sad that all the news sites and media providers only - or mainly - talk about the virus and it's aftermath. Life isn't just about drama and sickness, please! Wow.. so please tell me somebody what's there to know about this so called hespress. Thank you
