1What is the Phlogiston Theory and when was it created?
- ASimilar to previous theory, but states that it doesn't have mass. It cannot be created nor destroyed. lt flows from warm to cold substances; late 1700s
- BHeat is a fluid known as phlogiston, flows between different objects as "heat". This was disproved because it would mean heat has mass, which it doesn't.; 1700s
- CHeat is a form of energy and can be converted to different forms (kinetic, chemical, etc.). Specific heat capacity was created at this time; 1800s
- DThe more particles move, the more thermal energy is created. Energy cannot be created nor destroyed and it comes in many forms; modern day
