Allow Quote by William Henry Bragg
“Whenever we warm our hands by the fire, we allow the energy radiated by the fire to quicken up the movements of the atoms of which the hands are composed. When we cool any substance, we check those movements.”
About This Quote
Source Lecture: Physics of Heat, 1912
He explains that warming hands transfers energy to atoms, increasing their motion, while cooling reduces this motion.
In simple terms: Heat speeds up atomic motion; cooling slows it.
