What is matter
The definition of this word is "the capacity of one substance to dissolve in another substance."
What is solubility?

What are the characteristics of a solid?
Characteristics of a solid include having a definite shape and volume, and particles that are closely packed together and move in place.
What do we call two or more atoms joined together?

In lab, we had two test tubes containing substances in which being boiled in water. What was observed when heating butter and soap?
Hint: temperature..
Butter melts at a lower temperature (around 47-48°C) compared to soap, which remains solid until above 100°C, indicating they are different substances
