Answer:
they just add heat, then it turns to water vapor
Explanation:
The first h20 is water the arrow represents adding heat, and the second h20 represent water vapor (water as a gas)
Answer:
Boiling is not a chemical reaction. It is a physical reaction because after being heated up to a boil turning into steam, it eventually cools back down to water. Like evaporation and then rain.

The diagram shows a ball that is dropped and allowed to bounce.
During which two sections of the diagram does the ball's velocity increase?
A.D
B. B
C. A
D. C
Answer:
B and D
Explanation:
The diagram shows a ball that is dropped and allowed to bounce. In section B and section C does the ball's velocity increases. Therefore, option B and D are correct.
What is velocity ?The directional speed of an item in motion, as measured by a specific unit of time and observed from a certain point of reference, is what is referred to as velocity.
When an item is moving, its velocity is the rate at which it is changing position as seen from a certain point of view and as measured by a specific unit of time.
The normal velocity (vn) adds an inward component that is predicated to oscillate harmonically: Alternately, mention the boundary's v0 acceleration. The boundary condition is defined using the portion in the normal direction: An external source term is represented by this feature.
Thus, option B and D are correct.

Have you ever seen ash fly upward from a campfire? Use at least 2 sentences to explain what you think is happening to the ash to make it rise and which type of heat transfer is sending this ash into the sky.
Answer:
Convection
Explanation:
there are two types of heat transfer happening in this example. The first one is convection. As air is heated, it expands. As it expands, it becomes lighter than the surrounding air and it rises. It becomes ash. The second type of heat transfer happening is radiation. It is the type of heat one feels when sitting in front of a fireplace or around a campfire, As it is in this example.

1. What are electron energy levels? Where are they located?
Answer: Energy levels (also called electron shells) are fixed distances from the nucleus of an atom where electrons may be found. Electrons are tiny, negatively charged particles in an atom that move around the positive nucleus at the center. Energy levels are a little like the steps of a staircase.
Explanation:
Answer:
electrons are on the outside of the atom and are the smallest of the protons and neutrons. in something called an electron cloud with three levels in first level 2 electrons in the second 8 and in the third 10

Dry ice is a form of carbon dioxide that sublimates at room temperature. At a Halloween party, some students noticed that the dry ice underwent a phase change. Which statement below best describes the change in the energy and physical characteristics of the molecules of carbon dioxide during this process?
a: The molecules experienced a physical change from a gaseous state to a liquid state, releasing energy into the environment and reducing the molecular movement.
b: The molecules experienced a chemical change as the carbon dioxide reacted with oxygen, which released oxygen gas into the environment and increased the molecular movement.
c: The molecules experienced a physical change from a solid state to a gaseous state, which increased the molecular movement and the energy of the carbon dioxide molecules.
d: The molecules experienced a chemical change from a liquid state to a solid state, which reduced the amount of energy between the carbon dioxide molecules and decreased the molecular movement.

How do pumice and basalt form?
Answer:
Basalt forms when lava cools quickly at the surface. This quick cooling rate results in very small mineral grains. Pumice is formed when volcanoes erupt explosively. It comes from the same kind of magma which would form granite or rhyolite, that is, a magma that contains lots of silica (quartz). Magma with lots of silica is usually thick and sticky
Explanation:
Answer:
"If magma with the same composition reaches the surface, it forms extrusive rocks such as rhyolite and pumice. Basalt is an extrusive igneous rock that forms the ocean floor. ... Also, water and wind break apart and carry away surface rocks. Then deeper rocks are uncovered at the surface."

What is the difference in the number of neutrons between an atom of fluorine and an atom of argon?
I need an answer fast PLEASE!
The difference between the number of neutrons between an atom of fluorine and an atom of argon is 12
The number of neutrons is obtained by subtracting the number of protons from the mass number of the atom. We can calculate the number of neutrons in each element given this information
Mass number of fluorine = 19
Atomic number of fluorine = 9
Mass number of Argon = 40
Atomic number of argon = 18
Hence;
Number of neutrons in fluorine = 19 - 9 = 10
Number of neutrons in argon = 40 - 18 = 22
Difference between number of neutrons in argon and number of neutrons in fluorine = 22 - 10 = 12
