1.1. What was added to the solid to cause it What was added to the solid to cause it to melt? What would you take away from to melt? What would you take away from the system to make it re-solidify?the system to make it re-solidify?

2.2. How is a liquid transformed into a gas?How is a liquid transformed into a gas?3.3. How is a gas transformed into a liquid?How is a gas transformed into a liquid?4.4. In the popcorn and margarine model, In the popcorn and margarine model,

what does the margarine represent? what does the margarine represent? What do the popcorn kernels represent?What do the popcorn kernels represent?

Key TakeawaysKey Takeaways

Popcorn = atomsPopcorn = atoms Butter = bonds between atomsButter = bonds between atoms Exploding popcorn kernel = atoms going to gas Exploding popcorn kernel = atoms going to gas

phasephase the atoms are always movingthe atoms are always moving the more energy they have the faster they movethe more energy they have the faster they move When they get enough energy, the substance When they get enough energy, the substance
