This experiment demonstrates that iron can combust in air when heated. However, iron is a common material for cooking equipment such as cast-iron frying pans. Conduct research to find out why these pans are safe to use and do not combust, even if cooking over an open flame such as a campfire.

Imagine if during the cathode ray experiment, the size of the particles of the ray was the same as the size of the atom forming the cathode. which other model or scientific observation would have also been supported? 1. this would support dalton's postulates that proposed the atoms are indivisible because no small particles are involved. 2. this would support bohr's prediction about electrons moving in orbits having specific energy. 3. this would support bohr's prediction about electrons being randomly scattered around the nucleus in the atom. 4. this would support dalton's postulates that proposed that atoms combine in fixed whole number ratios to form compounds.
