Phase TransitionWater from the ocean gets into the atmosphere by evaporation.The water vapors in the atmosphere condense together by various processes to form different clouds.Clouds cool to a freezing temperature and become snows.Glaciers melt and the resulting water turns into nearby rivers.Cloud causes precipitation and the water goes into soils.More on cloud formation can be found here: https://brainly.com/question/1242352?referrer=searchResults
A 4.0g Glass was heated from 5°C to 45°C after absorbing 32 J of heat. What is the specific heat of the glass? 
Answer:
[tex]c=0.2\ J/g^{\circ} C[/tex]
Explanation:
Given that,
Mass of a glass, m = 4 g
Initial temperature, [tex]T_i=5^{\circ} C[/tex]
Final temperature, [tex]T_f=45^{\circ} C[/tex]
Heat absorbed, Q = 32 J
We need to find the specific heat of the glass. The formula for the heat absorbed is given by :
[tex]Q=mc\Delta T\\\\c=\dfrac{Q}{m\Delta T}\\\\c=\dfrac{32\ J}{4\ g\times (45-5)^{\circ} C}\\\\=0.2\ J/g^{\circ} C[/tex]
So, the required specific heat of the glass is [tex]0.2\ J/g^{\circ} C[/tex].

A 2.26 M solution of KOH is prepared. Calculate the moles and mass of solute present in a 15.2-mL sample of this solution. The molar mass of KOH is 56.11 g/mol.
Answer:
0.0344 moles and 1.93g.
Explanation:
Molarity is defined as the ratio between moles of a solute (In this case, KOH), and the volume. With molarity and volume we can solve the moles of solute. With moles of solute we can find mass of the solute as follows:
Moles KOH:
15.2mL = 0.0152L * (2.26mol / L) = 0.0344moles
Mass KOH:
0.0344 moles * (56.11g/mol) = 1.93g of KOH
Why must the red blood cells and the solution in the beaker be isotonic?
If a cell is placed in an isotonic solution, there will be no net flow of water into or out of the cell, and the cell's volume will remain stable. If the solute concentration outside the cell is the same as inside the cell, and the solutes cannot cross the membrane, then that solution is isotonic to the cell.

The compound cobalt(II) bromide is a strong electrolyte. Write the transformation that occurs when solid cobalt(II) bromide dissolved in water. Be sure to specify states such as (aq) or (s).
Answer and Explanation:
The chemical formula for cobalt(II) bromide is CoBr₂. As it is a strong electrolyte, it dissociates into ions when dissolved in water, according to the following chemical equation:
CoBr₂(s) → Co²⁺(aq) + 2 Br⁻(aq)
Thus, the compound CoBr₂ dissociates in water producing 1 mole of cobalt(II) ions (Co²⁺) and 2 moles of bromide ions (Br⁻) per mole of CoBr₂. The ions are dissolved in water, so they are in the aqueous state (aq).

What is the definition of climate?
1) An area's long term weather pattern
2)When large air masses of different density, moisture, and temperature mee
3)The state of the atmosphere at a given place and time
4)Large volume of air that has similar characteristics of temperature and water
vapor content
Answer:
1) An area's long term weather pattern
Explanation:
Climate is defined as the weather pattern in an area for the long term. Climate means the usual condition of the humidity, temperature, wind, rainfall, and atmospheric pressure in the surface area of Earth for the long term. Usually the time period for a climate in a region is taken over 30-years.
Weather is the state of the atmosphere and climate the long-term weather pattern of the area. For example: degree to which it is hot or cold is weather and expect snow in the Northeast in every January is climate.
Hence, the correct answer is "1) An area's long term weather pattern".
A mass m of water is at a temperature of 290K. The specific heat capacity of water is c. Ice, at its melting point, is added to the water to reduce the water temperature to the freezing point. The specific latent heat of fusion for ice is L. What is the minimum mass of ice that is required
Answer:
17 mc/L
Explanation:
We habe heat that is taken by the ice for it to melt to be equal to the heat given by water.
ML = mc(290K - 273K)
ML = mc 17
Then we divide through by L
M = 17 mc/L
Please note that 273k as we have used in thIs solution is the temperature at which we can have water to freeze
Therefore the minimum mass of required ice = 17 mc/L

Find the volume, in Liters, of 2.5 x 1024 molecules of chlorine gas at STP.
Answer:
V = 93.0 L
Explanation:
Hello!
In this case, when computing the PVT properties for an ideal gas, we need to use the following equation:
[tex]PV=nRT[/tex]
In such a way, for 2.5 x 10²⁴ molecules of chlorine at STP (273.15 K and 1.00 atm) we first need the moles based on the Avogadro's number:
[tex]n = 2.5x10^{24}molec*\frac{1mol}{6.022x10^{23}molec} = 4.15mol[/tex]
Now, we solve for volume on the ideal gas equation to obtain:
[tex]V=\frac{nRT}{P}[/tex]
So we plug in and get:
[tex]V=\frac{4.15mol**0.08206\frac{atm*L}{mol*K}*273.15K}{1.00atm}\\\\V=93.0L[/tex]

g Determine the oxidation state for each of the elements below. ... The oxidation state of ... phosphorus ... in ... phosphorous tribromide PBr3 ... is ... . The oxidation state of nitrogen in nitrogen gas N2 is . The oxidation state of arsenic in arsenic acid H3AsO4 is .
Answer:
- P in PBr3 is +3.
- N in N2 is 0.
- As in H3AsO4 is +5.
Explanation:
Hello!
In this case, since the determination of the oxidation states is performed by using the well-known charge balances, we can proceed as shown below:
- P in PBr3: Here, bromide ions have an oxidation state of -1, so we follow:
[tex]P^xBr_3^-\\\\x-3=0\\\\x=+3[/tex]
Thus, the oxidation state is +3.
- N in N2: Here, since nitrogen is bonding with nitrogen and it is neutral, we infer its oxidation state is 0.
- As in H3AsO4: Here, oxygen is -2 and hydrogen +1, so we follow:
[tex]H_3^+As^xO_4^{-2}\\\\3+x-8=0\\\\x=8-3\\\\x=5[/tex]
Thus, the oxidation state is +5.

Decide which element probably forms a compound with hydrogen that has a chemical formula most and least similar to the chemical formula of the compound formed by hydrogen and sulfur.
Answer:
Most similar- oxygen
Least similar- sodium
Explanation:
The complete question is shown in the image attached.
Now let us consider all the options in the questions carefully. We do know that hydrogen forms covalent bonds with sulphur. Two hydrogen atoms form form two polar covalent bonds with one sulphur atom. The molecule is bent owing to the presence of two lone pairs of electrons on the sulphur central atom.
Oxygen is in the same group as sulphur in the periodic table. The compound between hydrogen and sulphur is strikingly similar to the compound formed between sulphur and hydrogen due to chemical similarity of compounds of elements in the same group of the periodic table. Hence H2O bears the greatest similarity to H2S.
The bond between hydrogen and halogens is also polar covalent but less similar to the bond between sulphur and hydrogen.
Lastly, the bond between hydrogen and sodium is ionic and least similar to the bond between hydrogen and sulpur. We actually have in that compound, Na^+ H^-. Sodium transfers one electron to hydrogen as is implied in the ionic formula shown.
Hence the answer above.
If one force on an object is 5 N upward and the other is 10 N downward what is the objects motion?
To solve this we must be knowing each and every concept related to force. Therefore, the objects motion will be towards downward with a force of 5 N.
What is force?A force is an outside entity that has the power to alter a body's state of rest or motion. It has a direction and a magnitude. The point where forces are applied is determined by the the force's direction as well as the application of the force.
Newton and dyne units are used to measure the force exerted on an item. When using the centimeter kilogram second system of units, force is measured in dynes (CGS unit). In the common international system of units, it is denoted by the letter Newton (N) (SI unit).
upward force=5 N
downward force= 10 N
total force acting on body=downward force-upward force
= 10 N - 5 N
=5 N downward force
The objects motion will be towards downward with a force of 5 N.
Therefore, the objects motion will be towards downward with a force of 5 N.
