When water rises up a thin straw or moves up a tree from the roots to the leaves, it is called _____________.
Capillary Action
Surface Tension

The Earth is surrounded by a atmosphere made of water vapor. Which property allows us to consider Earth a "Goldilocks" planet based on this information.
High Specific Heat Capacity
Adhesion
Cohesion
Heat of Fusion
Why does ice float?
As water freezes, the molecules move farther apart (expands) and the density decreases.
As water freezes, the hydrogen bonds mix with air and create buoyancy.
As water freezes, the bonds break, making it float.
As water freezes, the molecules move closer together, causing the density to increase.
What makes water a universal solvent?
It is a polar molecule that can form hydrogen bonds, allowing it to dissolve many substances.
It is a nonpolar molecule that can form hydrogen bonds, allowing it to dissolve many substances.
It is a polar molecule with a low specific heat, allowing it to dissolve many substances.
It is a nonpolar molecule with a low specific heat, allowing it to dissolve many substances.
