Is evaporation a physical change?

Melting, evaporation and condensation are examples of physical change, or change of state, and are distinct from changes that cause new materials to form through a chemical reaction. Some curricula talk of physical changes as being reversible, and chemical change being irreversible.

Why does grass grow thicker in the Sun?

It also allows greater surface area to be exposed to the sun, which in turn allows for greater photosynthesis. This results in stronger, thicker grass with improved disease resistance. Slow-release fertilizers take time to break down.
