What is the main source of energy for the water cycle.
Answer:
The main source of energy is the sun. The sun has a big part in the water cycle because it turns the water into water vapor. This cause the water cycle to start over again once it rains. Therefore, making the sun ne of the biggest parts in the water cycle.
What causes water droplets to form on the outside of a glass?
Answer:
under me :)
Explanation:
There is water vapour present around us. When you put cold glass on a table, the water vapour comes in contact with the glass, and condenses, forming water droplets which are seen around the glass. Hope this helps

A weather map of Chicago with a high pressure system and warm front. Based on the weather map, what might the upcoming weather be like in Chicago? Warm, dry, clear skies Warm, humid, possible thunderstorms Cold, dry, clear skies Cool, humid, possible thunderstorms.
A weather map of Chicago with a high pressure system and warm front, so the upcoming weather be Warm, dry, clear skies in Chicago.
What is high pressure of air?High pressure of air tries to compress the gas from upper atmosphere to lower atmosphere.
When any gas has high pressure then it sinks towards the land from the upper atmosphere, and at the upper part air gets cool and form water vapor. When air comes towards the land then, it becomes warm and dry as it doesn't participate in the formation of precipitate. Due to which we are able to see clear sky at the dry days.
Hence, option (1) is correct i.e. Warm, dry, clear skies are the upcoming weather.

3. If a sample of gas occupies 6.80 L at 325oC, what will its volume be at 25oC if the pressure doesn't change
Answer:
V2 = 3.39
Explanation:
V1/T1 = V2/T2
V1 = 6.80L
T1 = 325C (must be convert to K by + 273.15) = 598.15 K
T2 = 25C = 298.15 K
V2 =?
T2xV1/T1 = V2
298.15 x 6.80/ 598.15 = V2
3.39 = V2
So 3.39 is the answer!

Crustal deformation builds landforms when two tectonic plates start to push into each other they can rise up and build mountains, or when they sink under, they create valleys.
How crustal deformation builds landforms?Tectonic pressure in a crust can cause folding. Folding can end up with the formation of valleys and mountains so we can conclude that when two tectonic plates start to push into each other they can rise up and build mountains, or when they sink under, they create deep valleys.

What is the difference between a nuclear and thermonuclear bomb.
Explanation:
the difference between a nuclear bomb and a thermonuclear bomb is that :
A nuclear bomb derives it's destructive force from nuclear reaction. That is,fission reaction, fusion reaction or both.
While thermonuclear bomb derives it's own force from a chain reaction in which isotopes of hydrogen combines under extremely high temperature to form helium under a process known as nuclear fusion.

Is boiling a chemical reaction?
Answer:
yes, because water is reacting with air and heat and creating a boiling effect.
Explanation: kracken doge
Answer: Freezing and boiling are considered to be examples of chemical reactions. This depends on their conception of substance. If students regard ice as a different substance from liquid water they are likely to classify the melting of ice as a chemical change.
Explanation:
Boiling water, boiling water is an example of a physical change and not a chemical change because the water vapor still has the same molecular structure as liquid water (H2O). No, boiling water is NOT a chemical reaction, but it is a physical change.
