Karen and Mary are camping in the woods. Karen used a match to light a camp fire. As she watched the the flame dance, Mary marveled at how such a little amount of energy (the match flame) could create such a large amount of energy (the fire). How should Karen correct Mary's statement?
Answers
Answer:the match didnt have all the energy its all the kindling or fuel in the fire
Explanation:
When Karen lit the match, it provided the initial heat energy required to start the combustion process in the campfire. However, the sustained and significant release of energy comes from the chemical reactions that occur as the wood and other materials burn. During combustion, the chemical bonds in the wood molecules break, releasing energy in the form of heat and light. This process continues as long as there is sufficient fuel and oxygen to sustain the fire.
In summary, while the match flame initiates the fire, it is the combustion of the campfire's fuel (wood and other materials) that generates the large amount of energy observed in the form of heat and light.

Which of the following is the best model to help explain how light behaves as it passes from air and then through a piece of transparent glass? Use evidence and scientific reasoning to support your answer. (It's very important)
Answers
The second one since when light is aimed towards transparent glass it does not reflect back to you, and you cannot see it through the glass.
The correct image that shows how the light behaves as it passes from air and then through a piece of transparent glass is second one, because, the light ray will refract or bend when passing to other medium with a different density.
What is refraction ?Refraction is the bending of light as it passes from one medium to another with a different density. The change in the speed of light as it moves from one medium to another causes the bending of the light, resulting in a change in its direction.
The amount of bending depends on the angle at which the light enters the new medium, as well as the difference in the refractive indices of the two media.
Refraction occurs when light passes through materials such as air, water, or glass, and it is responsible for a variety of optical phenomena, such as the way that lenses focus light to create images, the formation of rainbows, and the apparent bending of objects viewed through a glass of water.
Hence, the second image is correctly representing refraction.

Which property do we observe when we watch kids blowing bubbles? a density b color c solubility d flammability
Answers
Answer:
its a
Explanation:
We observe when we watch kids blowing bubbles it is a property of density. Therefore, option A is correct.
What is density ?The mass of a material per unit of volume is its density. Density is most frequently represented by the symbol, however Latin letter D may also be used. Mass divided by volume.
A liquid's density is a gauge of how heavy it is relative to the amount being measured. The liquid that weighs heavier is more dense if you weigh two liquids with similar volumes or quantities. A liquid that is less dense than water will float if it is gradually introduced to the water's surface.
By dividing a material's mass by its volume, the density of a substance may be estimated. The most common units for density are grams per milliliter, or g/mL, which is equivalent to grams per cubic centimeter.
Thus, option A is correct.

B. B
C. Sr
D. Kr
Answers
Answer:
The answer to this question is......C
Two or more than two atoms with different physical or chemical properties can not combine together to form an element. Therefore, Sr is the element which is most reactive. The correct option is option C.
What is element?Element generally consist of atoms or we can atoms combine to form element. Atoms of an element is always same, means all the properties of all atoms of one type of element is same.
On going down the group of periodic table, size increases due to increase in number of shells, easiness to eject one electron increases. Group 2 elements are the most reactive as it has only 2 electrons to loose. Sr is the element which is most reactive among all the given options.

What's the difference between evaporation and distillation with an example.?
Answers
Answer:
The main difference between evaporation and distillation is that evaporation is a process that involves a change in the state of matter while distillation is a process of separation. While the vaporization in evaporation occurs below the boiling point, the vaporization in distillation occurs at the boiling point.
Explanation:
Evaporation might occur when the sun heats up a puddle, and the water gets evaporated into the air. Distillation is a process used to purify water, and requires water to be boiled by a stove or fire.
