What is a hydrogen bond?
Air, helium in balloons, and water vapor are examples of which state of matter?
Gas
describes water’s ability to “climb” up objects
What is capillary action?
water held underground in the soil or in pores and in between rocks.
What is groundwater?
Which subatomic particle has a neutral charge?
A. Neutron
B. Electron

when a molecule has a negative side and a positive side because electrons are not shared evenly
What is polarity?
What are the 3 states of matter?
Solid, liquid, and gas.

What is volume?
water sticks to other water molecules at the surface or top
What is surface tension?
Rain, snow, hail, and sleet are examples of which part of the water cycle?
Precipitation
