reply to her in 25 ish words:In Module 14, Chapter 17: Change of Phase. This chapter covers the conversion of matter from one state to another. Matter exists as a solid, liquid, or gas; phase change is when it switches from one to another. Matter is made up of tiny particles that are in constant movement. Adding energy makes said particles move faster, removing energy slows particles down. Chapter 18: Thermodynamics. This chapter goes over the study of how heat and energy behave and interact with matter. There are 3 laws to thermodynamics. First law states that energy is conserved, can be transformed but it cannot be created or destroyed. Second law says the total entropy of an isolated system can only increase over time. Third law, as temperature approaches absolute zero, the system's entropy approaches minimum value
