The new volume is 800 L.

From <em>Charles’ Law</em>, we know that

<em>V</em>₁/<em>T</em>₁ = <em>V</em>₂/T₂

Then

<em>V</em>₂ = <em>V</em>₁ × <em>T</em>₂/<em>T</em>₁

<em>V</em>₁ = 200 L; <em>T</em>₁ = 100 K

<em>V</em>₂ = ?;        <em>T</em>₂ = 400 K

∴ <em>V</em>₂ = 200 L × (400 K/100 K) = 800 L

<h2>Answer</h2>

The volume will be<u> 50 L</u>

<h2>Explanation</h2>

From Kelvin Law of Temperature, we know that

V_{1} T_{1} =V_{2} T_{2}

We know that

V_{1} = 200 L

T_1 = 100 K

T_2= 400 K

So,

V_{2} = V_{1} T_{1}/T_{2}

V_{2} = 200*100/400

V_{2} = 50 L

The answer of the givern question is 50L

Explain how the following experimental errors affect the final calculation of the kilocalories per gram for a food item. Be spec
Ainat [17]

Answer:

a) the final kilocalories per gram for food will be less because the mass was reduced

b)the final kilocalories per gram for food will be less since

c) the final kilocalories per gram for food will be less since the reaction will eventually go to completion

d) the final kilocalories per gram for food will be more.

Explanation:

a) the final kilocalories per gram for food will be less because the mass was reduced from 110.3 to 101.3g

b)the final kilocalories per gram for food will be less since some marshmallow fell off before the reaction

c) the final kilocalories per gram for food will be less since the reaction will eventually go to completion

d) the final kilocalories per gram for food will be more since the thermometer that got stuck will add to the value of final kilocalories per gram

Identify the element whose highest energy electron would have the following four quantum numbers?
ad-work [718]

C. 6, 1, 0, -1/2

Explanation:

The four quantum numbers are:

  • Principal quantum number (n): this represents the energy level in which an orbital is located.
  • Azimuthal quantum number gives the shape of the orbitals in subshells accommodating the electrons.
  • Magnetic quantum number gives the number of spatial orientations or degeneracy of the orbitals in the subshells.
  • Spin quantum number describes the spinning of an electron in either clockwise or anticlockwise directions.

To know the electron with the highest energy, we use the principal quantum number values.

n values takes whole numbers i.e n = 1,2,3,4,5,6,7.............

The higher the value, the higher the energy level.

From the given quantum numbers, C has the highest energy levels.

Johanna makes the table below to organize her notes about centripetal forces. Which type of force should she place in the cell m
Valentin [98]

<u>Answer:</u> The correct answer is Option 2.

<u>Explanation:</u>

Centripetal force is defined as the force that acts on a body moving in a circular path and is directed towards the center around which the body is moving.

Mathematically,

F_c=\frac{mv^2}{r}

Where,

F_c = centripetal force

m = mass of the object

v = tangential velocity

r = radius of the path

From the above relation, X corresponds to the radius and Y corresponds to the tangential velocity.

Hence, the correct answer is option C.
