write a paragraph to explain how the transformation of water from one state of matter to another is important for the water cycle
Answers
In order for us to have water to drink, it first needs to go through a process called the water cycle. And in that water cycle there’s a process called evaporation. Evaporation is the process by which water changes from a liquid to a gas. In order for it to rain we need clouds and clouds are made of water. The water is heated causing water molecules to convert into gas, that gas then goes through a process called condensation creating clouds. At some point those clouds will be full of water, and all that water will then cause the cloud to release the water molecules causing rain.
The water cycle shows the continuous movement of water within the Earth and atmosphere. It is a complex system that includes many different processes.
Liquid water evaporates into water vapor, condenses to form clouds, and precipitates back to earth in the form of rain and snow.There are four main parts to the water cycle:
Evaporation, Convection, Precipitation and Collection.
Evaporation is when the sun heats up water in rivers or lakes or the ocean and turns it into vapor or steam.
The water vapor or steam leaves the river, lake or ocean and goes into the air.

If 10.5 g of iron, at 25°C, absorbs 128 J of heat, what will be the final temperature of metal? (The specific heat of iron is 0.449 J g-1 °C-1)
Answers
Answer:
27.5°C = Final Temperature of the metal
Explanation:
The change in temperature using the specific heat of a material could be obtained using the formula:
Q = m*S*ΔT
Where Q is heat absorbed in Joules = 128J in the problem
m is the mass of the substance = 10.5g
S is Specific Heat of the substance = 0.449J/g°C for Iron
ΔT is change in temperature = Final T - Initial T
Replacing:
128J = 10.5g*0.449J/g°C*ΔT
2.5°C = ΔT
2.5°C = Final T - 25°C
27.5°C = Final Temperature of the metal
How does the atmospheric pressure at altitudes above sea level compare with atmospheric pressure at sea level?
A. The atmospheric pressure above sea level is higher.
B. The atmospheric pressure at sea level is higher.
c. The pressures are the same.
D. Differences in pressures cannot be determined.
Answers
Answer:
Option B
The atmospheric pressure at sea level is higher.
Explanation:
Atmospheric pressure can simply be understood as the weight of the air molecules in the atmosphere. The higher we go up into the atmosphere, the thinner the air becomes. This means that the air present at higher heights is not so much, and hence, the air is lighter. This is why most fighter jets and mountain climbers need oxygen tanks to breathe properly.
Due to the fact that the air is less dense (lighter) at higher altitudes, it also means that the atmospheric pressure at higher altitudes is less.
Therefore, the atmospheric pressure at the sea level is higher than the atmospheric pressure at altitudes above sea level
Answer:
B. The atmospheric pressure at sea level is higher.

A substance has a boiling point of 78 °C. Which of the following is true about the substance? (5 points) a It will also change from a gas to a solid at 78 °C while the gas loses energy. b It will also change from a gas to a solid at 78 °C while the gas gains energy. c It will also change from a gas to a liquid at 78 °C while the gas loses energy. d It will also change from a gas to a liquid at 78 °C while the gas gains energy.
Answers
Answer: If a substance has a boiling point of [tex]78^{o}C[/tex] then it is true that it will also change from a gas to a liquid at 78 °C while the gas loses energy.
Explanation:
The temperature at which vapor pressure of a liquid substance becomes equal to the atmospheric pressure is called boiling point of substance.
At the boiling point, liquid phase and vapor phase remains in equilibrium.
This means that as liquid phase changes into vapor phase and also vapor phase changes into liquid phase at the boiling point.
Thus, we can conclude that if a substance has a boiling point of [tex]78^{o}C[/tex] then it is true that it will also change from a gas to a liquid at 78 °C while the gas loses energy.

If a gas takes up 250 ml at 800. torrand 50.°C, how much space will it take up at 400 torr and 25°?
A 125 ml
B 500 ml
0.46 L
D 0.542 L
Answers
Answer: The space occupied by the gas at 400 torr and [tex]25^{o}C[/tex] is 250 mL.
Explanation:
Given: [tex]V_{1}[/tex] = 250 mL, [tex]P_{1}[/tex] = 800 torr, [tex]T_{1} = 50^{o}C[/tex]
[tex]V_{2} = ?[/tex], [tex]P_{2}[/tex] = 400 torr, [tex]T_{2} = 25^{o}C[/tex]
Formula used is as follows.
[tex]\frac{P_{1}V_{1}}{T_{1}} = \frac{P_{2}V_{2}}{T_{2}}[/tex]
Substitute the values into above formula as follows.
[tex]\frac{P_{1}V_{1}}{T_{1}} = \frac{P_{2}V_{2}}{T_{2}}\\\frac{800 torr \times 250 mL}{50^{o}C} = \frac{400 torr \times V_{2}}{25^{o}C}\\V_{2} = 250 mL[/tex]
Thus, we can conclude that space occupied by the gas at 400 torr and [tex]25^{o}C[/tex] is 250 mL.

2.3g of lithium chloride in 500cm3 of solution
Answers
Answer:
0.109M
Explanation:
Find molarity of the solution:
Molarity is defined as the ratio between the moles of the solute (Lithium Chloride in this case) per liter of solution. To solve this question we have to find the moles of LiCl and its volume as follows:
Moles LiCl -Molar mass: 42.394g/mol-
2.3g * (1mol / 42.394g) = 0.0543 moles
Volume in liters:
500cm³ * (1L / 1000cm³) = 0.500L
Molarity:
0.0543 moles / 0.500L =
0.109M

5. A sample of an unknown metal has a mass of 120.4 g. As the sample cools from 90.5°C to 25.7°C, it releases 7020. J of energy. What is the specific heat of the sample? Identify the metal among those in the data table below. Finally, is this endothermic or exothermic?
Answers
Answer: The specific heat capacity of the sample is [tex]0.899 J/g^{o}C[/tex] and as heat is released in this reaction so it is exothermic in nature.
Explanation:
Given: Mass = 120.4 g
Heat energy released = -7020 J
Initial temperature = [tex]90.5^{o}C[/tex]
Final temperature = [tex]25.7^{o}C[/tex]
Formula used is as follows.
[tex]q = m \times C \times (T_{2} - T_{1})[/tex]
where,
q = heat energy
m = mass of substance
C = specific heat capacity
[tex]T_{1}[/tex] = initial temperature
[tex]T_{2}[/tex] = final temperature
Substitute the values into above formula as follows.
[tex]q = m \times C \times (T_{2} - T_{1})\\-7020 J = 120.4 g \times C \times (90.5 - 25.7)^{o}C\\C = \frac{-7020 J}{120.4 \times (-64.8^{o}C)}\\= \frac{7020 J}{7801.92} J/g^{o}C\\= 0.899 J/g^{o}C[/tex]
When heat is released in a process or reaction then it means it is exothermic in nature.
Thus, we can conclude that the specific heat capacity of the sample is [tex]0.899 J/g^{o}C[/tex] and as heat is released in this reaction so it is exothermic in nature.
What are the 3 most valuable metals in the United States? A. Lead b. Gold c. Iron d.Copper e.Coal f.Silver g.Titanium
Answers
Answer:
Gold, Silver and Titanium
Explanation:
The most valuable metals in the list are:
Gold:
Its value makes it a good investment option. Gold can be used in many different ways, like in jewelry, electronics, medicine, etc.
Silver:
Similar to the case of gold, besides the common value of silver in jewelry, it can be also used in other ways, because it has a large thermal and electrical conductivity.
Finally, the titanium: It's price is actually close to the copper one, but for the cost of work with titanium (Titanium has a really large melting point, then melting it into ingots needs a lot of energy), the price of titanium is increased.

Name the following alkene:
CH3CH2CH2CH2CH = CH2
Answers
Answer:
1-hexene. is your answer.
The name of the given alkene is Hex-1-ene
In order to name the given alkene, we will follow some of the IUPAC rules for naming alkenes. The rules are:
1. The longest chain chosen for the root name must include both carbon atoms of the double bond.
2.The root chain must be numbered from the end nearest a double bond carbon atom.
3. The smaller of the two numbers designating the carbon atoms of the double bond is used as the double bond locator.
The given alkene is
CH3CH2CH2CH2CH = CH2
The longest chain has 6 carbon atoms, which means it is a Hexene.
If numbered from the end nearest the double bond carbon atom, the double bond will be on carbon - 1
∴ Hex-1-ene
Hence, the name of the given alkene is Hex-1-ene
