Lesson 25

Lesson 25 mostly covered conductivity. Vocab word! Dissolve means to disperse evenly into another substance. For example, a solid can dissolve in a liquid. (common sense). Conductivity is a property that describes how well a substance transmits electricity. Something important to know is that substances that do not light up are compounds made up of C, H and O do not conduct! Also nonmetals do not conduct and metals do. Vocab time! Soluable means it is capable of being dissolved in another substance and insoluble means it doesn't! Homework below might help with any confusion!
