What happens to your energy when you move a heavy box?
Group of answer choices
It stays the same.
Some of it is transferred into the energy of the box.
None of it is transferred into the energy of the box.
It disappears.
Answer:
some of it sis transfered into the of the box
Explanation:
There is a kinetic energy upon moving the box thus will be force moving and the mass of the box converted to newtons
The energy when you move a heavy box - Some of it is transferred into the energy of the box.
Energy can not be generated or destroyed it can be transferred from one form to another, according to the thermodynamic law.
You put force on the box to move the box so you used some energy to do this work The system (box and Earth) gain gravitational potential energy equal to the amount of work that you have done on the box. The box and the Earth start from rest and finish at rest so there is no change in the kinetic energy of the system. the energy is transferred to the box in the form of potential energyThus, The energy when you move a heavy box - Some of it is transferred into the energy of the box.

The geometric shape of crystals indicate that:
A)the atoms which make the mineral can take any form
B)the inside of the crystal is liquid
C)the atoms have an orderly arrangement
D)it was formed from a mold
Answer: C) The atoms have an orderly arrangement
Explanation: Every crystal has an orderly, internal pattern of atoms, with a distinctive way of locking new atoms into that pattern to repeat it again and again. The shape of the resulting crystaL-such as a cube (like salt) or a six-sided form (like a snowflake)-mirrors the internal arrangement of the atoms.
The geometric shape of crystals indicates that the atoms have an ordered arrangement that is present in Option C, as the crystal structure and the properties differ as per the crystal's geometric pattern.
What is the significance of the crystals?Crystals have significance in various fields, such as science, technology, and spirituality, in science, they are studied for their structure and properties for applications in fields such as electronics, optics, etc. Other fields, such as astrology, have different uses for crystals, as they are used for healing purposes such as energy concentration and so on.
Hence, the geometric shape of crystals indicates that the atoms have an ordered arrangement that is present in Option C, as the crystal structure and the properties differ as per the crystal's geometric pattern.

Explanation:
Describe an example of an endothermic and exothermic reaction. For each of your reactions, identify whether it is a physical or chemical change and explain how the reaction supports the law of conservation of mass.
Answer:
he sum of the enthalpies of the reactants is greater than the products, the reaction will be exothermic.
Explanation:
The law of conservation of mass is obeyed by both endothermic and exothermic equations ,
What is endothermic reaction and exothermic reaction?An exothermic process releases heat, causing the temperature of the immediate surroundings to rise.
An endothermic process absorbs heat and cools the surroundings.
According to the question
An example of an endothermic reaction:
[tex]CaCO_{3}[/tex] + heat → CaO + [tex]CO_{2}[/tex]
An example of an exothermic reaction:
C(g) + [tex]O_{2}[/tex](g) → [tex]CO_{2}[/tex] (g) + Heat Energy
Chemical reaction:
Chemical reactions occur when chemical bonds between atoms are formed or broken. The substances that go into a chemical reaction are called the reactants, and the substances produced at the end of the reaction are known as the product
Physical reaction:
The physical reaction definition is a reaction in which molecules undergo molecular rearrangement but are not chemically altered. Physical reactions may include changes in texture, shape, temperature, and state, without a change in the composition.
Therefore,
both example of endothermic and exothermic example mentioned are chemical reaction as in both bonds are broken and formed
Now,
The law of conservation of mass states that in a chemical reaction mass is neither created nor destroyed and every balanced equation obeys the Law of Conservation of Mass.
In first endothermic :
[tex]CaCO_{3}[/tex] + heat → CaO + [tex]CO_{2}[/tex]
As the reaction is balanced , if we examine both the sides elements are in equal proportion
i.e mass is neither created nor destroyed
In second exothermic :
C(g) + [tex]O_{2}[/tex](g) → [tex]CO_{2}[/tex] (g) + Heat Energy
If 6 gm carbon combines with 16 gm of oxygen to form 22 gm of carbon dioxide.
I.e mass is neither created nor destroyed
Hence, The law of conservation of mass is obeyed by both endothermic and exothermic equations ,

Why is the sun orange and red at sunrise and sunset?
A) Gases absorb orange and red light
B) Blue wavelengths are absorbed by the atmosphere
C) The thick atmosphere scatters all but longer wavelengths.
D) Only short wavelengths are radiated from the Sun in the morning and evening.
Answer:
C
Explanation:
Because the sun is low on the horizon, sunlight passes through more air at sunset and sunrise than during the day, when the sun is higher in the sky. More atmosphere means more molecules to scatter the violet and blue light away from your eyes. ... This is why sunsets are often yellow, orange, and red.

Areas near oceans or large lakes tend to have more moderate climates than do areas far from large bodies of water. Which of these statements best explains this observation?
a. Hydrogen and oxygen atoms share electrons in a water molecule.
b. Water has a very high specific heat.
c. Lakes and oceans contain dissolved solids.
d. Water produces buoyant forces.
Answer:
B
Explanation: The specific heat of any particular substance is usually defined as the amount of heat energy that is required to raise a unit mass of the material by 1°C. The water has this high heat capacity as a result of which the water bodies such as oceans, seas, and lakes tend to become hot and cold at a much slower rate.
