Answer:
300K.
Explanation:
The following data were obtained from the question:
Initial volume (V1) = 300L
Initial temperature (T1) = 200K
Final volume (V2) = 450L
Final temperature (T2) =..?
Since the pressure is constant, the gas is obeying Charles' law.
Using the Charles' law equation, we can obtain the new temperature of the gas as follow:
V1/T1 = V2/T2
300/200 = 450/T2
Cross multiply to express in linear form
300 x T2 = 200 x 450
Divide both side by 300
T2 = (200 x 450)/ 300
T2 = 300K
Therefore, the new temperature of the gas is 300K.
Its A because the number if every element on one side is equal to the number of elements on the other?
Electric current is the flow of electrons in a wire. In metals, the outer electrons of the atoms belong to a 'cloud' of delocalised electrons. They are no longer firmly held by a specific atom, but instead they can move freely through the lattice of positive metal ions. ... Metals are good conductors of heat.

Answer:
The correct answer to the following question will be Option E (1.0 x 10⁻³ M).
Explanation:
The given values are:
![A\lambda =140](https://tex.z-dn.net/?f=A%5Clambda%20%3D140)
![\varepsilon=1.36\times 10^5 \ M \ {cm^{-1}}](https://tex.z-dn.net/?f=%5Cvarepsilon%3D1.36%5Ctimes%2010%5E5%20%5C%20M%20%5C%20%7Bcm%5E%7B-1%7D%7D)
L = 1 \ cm
As we know,
⇒ ![A\lambda=\varepsilon CL](https://tex.z-dn.net/?f=A%5Clambda%3D%5Cvarepsilon%20CL)
On putting the given values in the above formula, we get
⇒ ![140=1.36\times 10^5\times C\times 1](https://tex.z-dn.net/?f=140%3D1.36%5Ctimes%2010%5E5%5Ctimes%20C%5Ctimes%201)
⇒ ![C=\frac{140}{1.36\times 10^5}](https://tex.z-dn.net/?f=C%3D%5Cfrac%7B140%7D%7B1.36%5Ctimes%2010%5E5%7D)
⇒ ![C=102.9\times 10^{-5} \ M](https://tex.z-dn.net/?f=C%3D102.9%5Ctimes%2010%5E%7B-5%7D%20%5C%20M)
So that option E is the right answer.
