1) pretty much any material can change state - if the conditions are right.
2) On Earth, with our temperature range and air pressure, water can exist in all 3 states ... although its mainly ice and liquid. The vapor pressure is low.

Is water evaporating from a pond a chemical or a physical change?
Evaporation from a pond is not a chemical change. It is a physical change. The water that leaves the pond and goes into the air is not changed from water into some other chemical compound. It's still water, but in the form of a vapor or gas. As the water doesn't chemically change, evaporation is a physical change and not a chemical one.
When a cloud forms in the sky is that a physical or chemical change?
A physical change; more water vapour has joined the cloud, making it thicker and less able to allow light through.
How would life be different without chlorine?
we wouldnt be able to purify water
What change would increase the amount of gas able to be dissolved in a given amount of liquid water?
Increasing pressure.
If water were a nonpolar molecule how would its properties be different?
water would not be able to form hydrogen bonds (wrong)Apex - Water would not rise inside plants :P
Does a change in state mean that a new substance has formed?
In a "physical change" a new substance is not created. In a "chemical change" a new substance is created. This applies to changes in states of matter. For example, ice, water, and steam are all the same substance, even though they exist in three different states. The elements of which they are comprised do not change. Sometimes you may be able to precipitate elements out of a substance through a phase change. In a mixture of alcohol and water you can fairly quickly boil out the alcohol.
Why water should be called liquid?
water can have different states. you can read a phase diagram of water to see that only within a certain temperature and pressure for water to be in liquid state ~Also: You are able to get wet by it and it has no definite shape.

What is the different between water lettuce and water hyacinth able to stay afloat in water?
they float
Can a physical change be reversed?
yes they can because if you freeze water that doesn't prevent you from being able to change the water back into its original state
Are bacteria able to change to a different type of bacteria?
No! because bacteria is its type of bacteria and no matter what it will not change!
Where in Tennessee are you able to see 5 different states?
On the U.S. map, of course!
