What is the state change of a gas to a liquid is called?
Answers
Answer:The process in which a gas changes to a liquid is called condensation. Other examples of condensation are shown in Figure below. A gas condenses when it is cooled below its boiling point.
Explanation:
There are 4 phases for h20 solid liquid vapour and gas.
In the vacuum of space there are only 2 phases solid and gaseous, both liquid and vapour cannot exist in the absolute freezing temperature of the vacuum of space and crystalise instantly.
Watch a space shuttle dump water in space and it instantly freezes, and when in direct sunlight instantly turn to its gaseous phase and becomes invisible to the naked eye by the process of sublimation.
When h20 freezes in the shadow of the shuttle to ice crystals they instantly sublimate to the a gaseous state when they come into contact with direct sunlight.
You can see all 4 phases if you place ice cubes [ solid phase ] in a pan on a stove, the Solid beComes liquid [ liquid phase ]and the liquid becomes a gas in the bottom of the pan when the water boils, [ gaseous phase ] the bubbles coming up from the bottom are the instant phase change from liquid to gas, when the gas bubbles break the surface of the water and the gas comes into contact with the cooler air the gas instantly starts to condense to water droplets i.e. the vapour phase
You can see through the bubbles because h20 in its gaseous phase is invisible to the naked eye.
Gaseous h20 is hot dry and invisible
Vaporous h20 is warm wet and visible
Gaseous h20 is known as a condensing gas in physics because it condenses obviously, condensing gases are also known as optically active gases or radiatively active gases.
Hope this helps all the 3 phase numpties who think vapour i.e. water droplets is actually gas, it isnt or it wouldn’t be called vapour it would be called gas.
Liquid water has to reach its boiling point before it will phase change to its gaseous phase.
Vapor has to boil before the water droplets will phase change to a gaseous state, steam is not gas it is condensing gas i.e. vapour at a lower temperature than boiling point.
hope this helps have a nice day

A 12.0 L balloon at 84 °C is cooled until it
becomes 5.0 L. To what temperature was
the balloon cooled?
Answers
Here, V1 = 12.0 L, T1 = 357.15 K, and V2 = 5.0 L. To solve for T2, we rearrange the equation and compute:
T2 = V2T1/V1 = (5.0 L)(357.15 K)/(12.0 L)
T2 = 148.8125 K - 273.15 = -124.34 °C
To two significant figures, the answer would be -120 °C.
The ideal gas relates the volume, pressure, and temperature to each other. The balloon was cooled to -120 degrees celsius.
What is Charle's law?Charle's law states the direct relationship between the volume and the temperature of the hypothetical gas. The law is given as,
[tex]\rm \dfrac{V_{1}}{T_{1}} = \rm \dfrac{V_{2}}{T_{2}}[/tex]
As it can be seen from the question the volume of the gas in the balloon is decreasing so the temperature will also decrease.
Given,
Initial volume = 12.0 L
Final volume = 5.0 L
Initial temperature = 357.15 K
The final temperature is calculated as:
[tex]\begin{aligned} \rm T_{2} &= \rm \dfrac{V_{2}T_{1}}{V_{1}}\\\\&= \dfrac{5\times 357.15}{12}\\\\&= 148.81\;\rm K\end{aligned}[/tex]
Therefore, -120 degrees celsius is the final temperature of the balloon.

The kinetic energy is then transformed into electrical energy. i What is the source of the energy that turns the turbine in the power plant? Chemical energy of water molecules as they fall Gravitational potential energy of water behind the dam Elastic potential energy of the water molecules as they bounce over the dam Electrical energy from power lines that connect the hydroelectric plant to a grid
Answers
Answer:
Gravitational potential energy of water behind the dam
Explanation:
Energy can be defined as the ability (capacity) to do work. The two (2) main types of energy are;
a. Gravitational potential energy (GPE): it is an energy possessed by an object or body due to its position above the earth.
b. Kinetic energy (KE): it is an energy possessed by an object or body due to its motion.
Hydroelectric power plant refers to a renewable source of energy used for the generation of electricity, through the use of powerful hydraulic steam turbines operating at high voltage and are being driven by the energy acquired by water falling from a height and flowing through a penstock (pipe) i.e the mechanical energy (gravitational potential energy + kinetic energy).
At a hydroelectric power plant, potential energy is changed into kinetic energy. The kinetic energy is then transformed into electrical energy.
The source of the energy that turns the turbine in the power plant is Gravitational potential energy of water behind the dam, usually from streams or rivers.

A 20 ml of 0.27M of solution of the salt NaA has a pH of 8.70. Calculate the pKa value of the acid HA.
Answers
Answer:
pKa = 3.97
Explanation:
Let's state the equations:
NaA → A⁻ + Na⁺
A⁻ + H₂O ⇄ OH⁻ + HA Kb
We don't have the concentration of [OH⁻] but we do know pH, so we can determine, pOH and after that, [OH⁻].
14 - pH = pOH → 14 - 8.70 = 5.30
10^-pOH = [OH⁻] → 10⁻⁵'³⁰ = 5.01×10⁻⁶ M
Initially we can know, the moles of base, we had.
20 mL . 0.27M = 5.4 mmoles. So now, let's make the expression for Kb.
Kb = [OH⁻] . HA / [A⁻]
As the [OH⁻] is so low, we can assume, there where no loses and the salt is well concentrated. So:
Kb = (5.01×10⁻⁶)² / 0.27 → 9.29×10⁻¹¹
Kw = Ka . Kb, then Ka = Kw/ Kb
Ka = 1×10⁻¹⁴ /9.29×10⁻¹¹ = 1.08×10⁻⁴
pKa = - log Ka → - log 1.08×10⁻⁴ = 3.97

The equilibrium constant, Kc, for the reaction below is 0.10 at 25oC. Find the equilibrium concentration of chlorine gas, Cl2(g), if the equilibrium concentrations of ICl(g) and I2(g) are known to be 0.50 M and 0.40 M respectively.
2 ICl(g) → Cl2(g) + I2(g)
Answers
Answer:
The equilibrium concentration of chlorine gas, Cl₂(g), is 0.0625 M
Explanation:
Chemical equilibrium is established when there are two opposite reactions that take place simultaneously at the same speed, so that no changes are observed as time passes, despite the fact that the substances present continue to react with each other.
The mathematical expression that represents Chemical Equilibrium is known as the Law of Mass Action and is stated as: The ratio of the product of high concentrations to the stoichiometric coefficients in the reaction of products and reactants remains constant at equilibrium. For any reaction:
aA + bB ⇄ cC + dD
the equilibrium constant Kc is calculated as:
[tex]Kc=\frac{[C]^{c} *[D]^{d} }{[A]^{a} *[B]^{b}}[/tex]
In this case, you have:
2 ICl(g) → Cl₂(g) + I₂(g)
So, the equilibrium constant Kc is:
[tex]Kc=\frac{[Cl_{2} ]*[I_{2} ]}{[ICl]^{2} }[/tex]
Being:
Kc= 0.10[Cl₂]= ?[ICl]= 0.50 M[I₂]= 0.40 MReplacing:
[tex]0.1=\frac{[Cl_{2} ]*0.40 M}{(0.50 M)^{2} }[/tex]
Solving:
[tex]0.1=\frac{[Cl_{2} ]*0.40 M}{0.25 M^{2} }[/tex]
0.1= 1.6 [tex]\frac{1}{M}[/tex]* [Cl₂]
[Cl₂]= 0.1 ÷ 1.6 [tex]\frac{1}{M}[/tex]
[Cl₂]= 0.0625 M
The equilibrium concentration of chlorine gas, Cl₂(g), is 0.0625 M
The equilibrium concentration of chlorine gas, if the equilibrium concentrations of ICl(g) and I₂(g) are known to be 0.50 M and 0.40 M respectively is 0.0625M.
How we calculate the equilibrium constant?Equilibrium constant for any reaction will be define as the ratio of the concentration of products to the concentration of reactants with raise to their respective coefficients.
Given chemical reaction is:
2ICl(g) → Cl₂(g) + I₂(g)
Equilibrium constant for this reaction will be calculated as:
Kc = [Cl₂][I₂] / [ICl]², where
Kc = equilibrium constant = 0.10
[I₂] = concentration of iodine gas = 0.40 M
[ICl]² = concentration of ICl = 0.50 M = (0.50M)² = 0.25M²
[Cl₂] = concentration of chlorine gas = to find?
On putting all these values on the above equation and calculate for the value of [Cl₂] as follow:
[Cl₂] = Kc × [ICl]² / [I₂]
[Cl₂] = (0.10)(0.25) / (0.40)
[Cl₂] = 0.0625M
Hence, equilibrium concentration of chlorine gas is 0.0625M.
