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.
What is an example of a state of matter beside ice?
An example of a state of matter besides ice is liquid water. Water is able to exist in three different states - solid (ice), liquid (water), and gas (water vapor) - depending on the temperature and pressure conditions.
When antacid and water are mixed what kind of change occurs physical or chemical?
Students will be able to distinguish between physical and chemical changes. ...Prepare the bread dough in the mixing bowl as directed on the box. ...kinds of liquids, or bubbling the gas through the solution and allowing it to dissolve). ...The change thatoccurs when an Alka-Seltzer tablet is added to wateris chemical.
What cycles depends on the fact that water is able to exist as a solid a liquid and a gas on Earth The nitrogen cycle the water cycle the carbon cycle or the phosphorus cycle?
The cycle that depends on water existing as a solid, liquid, and gas on Earth is the water cycle. This cycle involves processes like evaporation, condensation, and precipitation, which are facilitated by water's ability to exist in these different states.
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.
How will you justify that ice and water and steam are different states of water?
Ice, water, and steam are different states of water because they have different molecular arrangements and levels of energy. In ice, water molecules are in a rigid and ordered structure. In water, molecules are more loosely packed and able to flow. In steam, molecules have high energy and are moving freely as a gas.
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
Where in Tennessee are you able to see 5 different states?
On the U.S. map, of course!
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!

If water was a non-polar molecule how would the properties of water be different?
Water would not be able to for hydrogen bonds
