>>17791768temperature is a measures of the average kinetic energy of molecules vibrating and colliding in a substance
you could take the temperature of water, let's say at room temperature, but some molecules in the water are "hotter" than what the temp says and escapes, they slowly "evaporate" just like it would when boiling the water only in smaller amounts
no matter the instrument or method temperature is never actually accurate
so do you want a useful term like temperature or some lengthy explanation for everything in life? are you on average the same minute by minute?
