Question 1
Question
What is the Phlogiston Theory and when was it created?
Answer
-
Similar 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
-
Heat 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
-
Heat is a form of energy and can be converted to different forms (kinetic, chemical, etc.). Specific heat capacity was created at this time; 1800s
-
The more particles move, the more thermal energy is created. Energy cannot be created nor destroyed and it comes in many forms; modern day

Question 17
Question
Kinetic energy is the energy of [blank_start]MOVEMENT[blank_end]
Potential energy is [blank_start]STORED[blank_end] energy:
- [blank_start]Elastic[blank_end] potential energy is when an object is bend/compressed and has stored energy to return to its original shape
- [blank_start]Chemical[blank_end] potential energy is the stored energy in the bonds of chemicals
- [blank_start]Gravitational[blank_end] potential energy is the stored energy from the attraction between two objects
Mass is measured in [blank_start]kg[blank_end] and is the [blank_start]amount of space something takes up[blank_end]. Weight is the [blank_start]mass + gravity[blank_end].
