What is the secret behind the sound when NaCl is on fire?
I have a question about the sound when NaCl is on fire. What is the secret behind that sound?
The sound that is produced when NaCl is set on fire is due to the release of energy in the form of heat and light. When the NaCl is heated, the atoms are excited and move around at a faster rate. As the NaCl burns, the heat energy is released, which causes the air around it to vibrate and produce sound waves.
