help asap show work | a gas with a volume of 13L at a pressure of 197 kPA is allowed to expand to a volume of 23L. what is the pressure of the container if the temperature remains constant
Answer:
111 kPaExplanation:
The new pressure can be found by using the formula for Boyle's law which is
[tex]P_1V_1 = P_2V_2[/tex]
where
P1 is the initial pressure
P2 is the final pressure
V1 is the initial volume
V2 is the final volume
Since we're finding the new pressure
[tex]P_2 = \frac{P_1V_1}{V_2} \\[/tex]
We have
[tex]P_2 = \frac{13 \times 197000}{23} = \frac{2561000}{23} \\ = 111347.826...[/tex]
We have the final answer as
111 kPaHope this helps you

You observe mothballs disappearing in cabinets. What do you think is the reason for this? Do all substances behave like mothballs at normal conditions? Explain by citing some examples Need lang po for science ;(
Answer: Mothballs have weak intermolecular forces.
No all substances do not behave like mothballs at normal conditions. Example: benzene , chloroform
Explanation:
Sublimation is a process of converting a substance from solid state to gaseous state without the formation of liquid at constant temperature.
A substance which undergoes sublimation is called as sublimating substance.
As mothballs is made of napthalene which has weak inter molecular forces of attraction between its molecules, it directly sublimes into gaseous state without leaving any residue and is called as a sublimating substance.
Not all substances behave like mothballs at normal conditions. Example: benzene , chloroform
Due to weak intermolecular attraction force mothballs will disappear and not every compound show this type of behavior like benzene and chloroform.
What are mothballs?Mothballs are also known as Naphthalene balls, they are the aromatic organic compounds and they are the members of the sublimating substance family as they directly convert into gaseous state from the solid state.
In the mothballs or naphthalene balls, there is a weak attraction of force London dispersion force is present between their constitute particles, and in normal condition they show sublimation and gets disappear. Not all aromatic compounds behave like these balls as not in all compounds these types of force present, for example in benzene and chloroform strong covalent bond is present.
Hence, not all compounds behave like mothballs and they show that property due to weak attraction force.

Answer:
Entropy is a measure of the degree of spreading and sharing of thermal energy within a system. For an ideal gas that expands at a constant temperature (meaning that it absorbs heat from the surroundings to compensate for the work it does during the expansion), the increase in entropy is given by ΔS= R1n (V2/V1)

Electrolysis is defined as a process of decomposing ionic compounds into their elements by passing a direct electric current through the compound in a molten form.
Characteristics of negative electrode -:
The negative electrode in an electrolytic cell, is the one toward which positively charged particles are attracted.
The cathode has a negative charge because it is connected to the negatively charged .
When an electrolyte is dissolved in water and an electric current is passed through it, the Cations move towards the cathode and Anions move towards anode .
Cu will be produced at the negative electrode for the following reaction:
2CuSO4 (a q) + 2H20 (1) -> 2Cu(s) + 2H2SO4(l) + O2(g) ,hence option (b) is correct.

When the pressure is in a certain gas cylinder with a volume of 4.50 L reaches 500atm, the cylinder is likely to explode. If this cylinder contains 40.0 moles of argon at 25.0°C, is it on the verge of exploding? Calculate the pressure
Answer:
The cylinder is nit on the verge of exploding.
Explanation:
Temperature= 25.0°C
The conversion of T(°C) to T(K) is shown below:
T(K) = T(°C)+ 273.15
So,
T=(25.0 + 273.15) K = 298.15 K
Volume= 4.50 L
Moles= 40.0 mol
Using ideal gas equation as:
PV = nRT
where,
P is the pressure
V is the volume
n is the number of moles
T is the temperature
R is gas constant having value = 0.0821 Latm/ K. mol x 298.15 K
⇔ P= 217.58 atm
Pressure limit = 500 atm .

What is a gluon?
A. A particle that binds quarks to one another
B. A radioactive particle
C. An electrostatic force
D. A weak nuclear force
Answer:
A
Explanation:
it binds quarks together
In quantum chromodynamics the theory of the strong force, the interactions of the quarks are described in terms of eight types of massless gluon. A gluon is a particle that binds quarks to one another. The correct option is A.
What is gluon?The gluon, so called the messenger particles is defined as the strong nuclear force which binds the subatomic particles known as quarks within the protons and neutrons of stable matter as well as within heavier short-lived particles at high energies.
It has been found that the quarks interact by emitting and absorbing gluons just as electrically charged particles interact through the emission and absorption of photons. Like quarks the gluons carry a strong charge known as colour. This means that gluons can interact between themselves through the strong force.
The gluons have no electric charge.
Thus the correct option is A.

plssss show your work will mark the brainliest
Answer:
135.16 mL
Explanation:
From the question,
Applying,
PV/T = P'V'/T'.................... Equation 1
Where P = Initial pressure of the gas, V = Initial volume of the gas, T = Initial Temperature of the gas in Kelvin, P' = Final pressure of the gas, V' = Final Volume of the gas, T' = Final temperature of the gas in Kelvin.
Make V' the subject of the equation
V' = PVT'/TP'................... Equation 2
Given: P = 600 torr, V = 115 mL, T = 50 °C = (50+273) K = 323 K, T' = 75 °C = (75+273) K = 348 K, P' = 550 torr
Substitute these values into equation 2
V' = (600×115×348)/(323×550)
V' = 24012000/117650
V' = 135.16 mL

m = ?
c = 4.19
Δt = 63 - 18 = 45
Solution
28242 = m * 4.19 * 45
28242 = m * 188.55
