Which statements demonstrate the law of conservation of matter? (Select all that apply.)
water evaporating in the water cycle which is an open system
water freezing
cookie dough is baked into a cookie
sugar dissolving into water
Water evaporating in an open system, water freezing, cookie dough baked into a cookie, and sugar dissolving into water are all examples of statements that demonstrate the law of conservation of matter.
What is law of conservation?A conservation law in physics asserts that a specific observable property of an isolated physical system doesn't change over time.A physical property, or measurable amount, does not change over time in an isolated physical system, according to the conservation law, often known as the law of conservation, which is a principle in physics.According to the principle of mass conservation, neither chemical processes nor physical changes can create or destroy mass in an isolated system. The mass of the products and reactants of a chemical reaction must be equal, in accordance with the law of conservation of mass.To learn more about law of conservation refer to:

Describe how a chemical change follows the law of conservation of matter.
give examples pls
Answer: In any chemical change, one or more initial substances change into a different substance or substances. ... According to the law of conservation of matter, matter is neither created nor destroyed, so we must have the same number and kind of atoms after the chemical change as were present before the chemical change.
Explanation:
identify the for of energy
(A)mechanical energy
(B)chemical energy
(C)radiant energy
(D)electrical energy
Answer:
Mechanical energy is the energy that is possessed by an object due to its motion or due to its position
Chemical energy is energy stored in the bonds of chemical compounds, like atoms and molecules
Radiant energy, energy that is transferred by electromagnetic radiation, such as light, X-rays, gamma rays, and thermal radiation
The flow of electric charge (usually electrons) is electric current.

(HELP I DONT KNOW HOW TO DESCRIBE IT BUT I SEE THE SIMILARITIES) Look at the green lines you created by connecting the three boiling point data points and the three melting point data points. For each of these lines, describe any trends you see.
Answer: There will be an increase in the boiling point with an increase in the molecular mass.
Explanation:
The melting point is the temperature at which the substance changes from a liquid state to a vapor state at a constant pressure. The pressure required to effect this change is known as the vapor pressure. The higher the vapor pressure, the higher the boiling point and the lesser time it takes for the substance to escape from the liquid state. In this case, a higher molecular mass means more energy is needed to make sure that there is a gaseous change. In addition, the higher melting point requires the lower temperature as well.

The electromagnetic spectrum is the portion of energy that reaches the Earth from the Sun. However, the human eye can still only detect a portion of that spectrum because of the _____________ of the visible light waves.
amplitude
wavelengths
crests
troughs
Answer: I’m stuck between amplitude and wavelengths but I do think it’s wavelengths.
Correct me if I’m wrong! ^^
The human eye can only detect a portion of that spectrum because of the wavelength of the visible light waves. Therefore, option (B) is correct.
What are frequency and wavelength?The wavelength of the light can be defined as the distance between the two adjacent points of a wave w.r.t. each other. Two crests on a wave are separated by a distance known as wavelength.
The frequency of the wave can be defined as the number of oscillations of a wave in 1 sec. The frequency has S.I. units per second or hertz.
The relationship between wavelength, frequency (ν), and speed of light (c) is as follows:
c = νλ
The part of the electromagnetic spectrum that is visible to the human eye is known as the visible spectrum. The electromagnetic radiation of the visible spectrum is known as visible light.
Human eyes can detect the wavelength of range from 380nm to 740nm. This wavelength range of visible light corresponds to a band of frequency between 405 THz to 790 THz.

Which is the Milky Way?(1 point)
A) A galaxy that does not include our solar system
B) A dwarf galaxy
C) Galaxy containing earth(i think this one is right)
D) Galaxy destroyed in collision
Answer:
C
Explanation:
The Milky Way is the galaxy that includes the Solar System, with the name describing the galaxy's appearance from Earth: a hazy band of light seen in the night sky formed from stars that cannot be individually distinguished by the naked eye.
Milky Way can be referred to as the galaxy which contains Earth . The milky way also comprises of other solar systems such as the Sun and billions of stars.
The name 'milky way' came about as a result of how the sky looks when viewing it at night. It contain several bands of color in a milky manner which are usually difficult to differentiate.
The milky way comprises of different processes such as force of gravity acting on it and also the channeling of energy needed to produce stars which aids vision in the night.

1. Why did the naked egg swell when it is placed in water?
2. Why did the swollen naked egg shrink when it is placed in corn syrup??
Answer:
1.porque la cáscara del huevo es semipermeable, es decir, hay sustancias que pueden pasar al interior del huevo o salir de él. En esta ocasión parte del líquido ha entrado dentro del huevo
2.Los huevos se encogen en el jarabe de maíz debido a la ósmosis. La ósmosis es el proceso por el cual el agua entra y sale de las células a través de una membrana semipermeable.
El agua entra y sale de los tejidos a través de la ósmosis. Durante la ósmosis, el agua entra o sale de la célula a través de la membrana semipermeable de la célula. Esta membrana es esencial para permitir que los materiales vitales entren en las células sin permitir el paso de materiales no deseados o peligrosos. Durante la ósmosis
