When a piston is pushed down on a cylinder, the pressure on the gas in the cylinder increases from 125 kPa to 375 kPa. The initi
Elden [556K]

Answer:

The final volume is 1.1 L.

Explanation:

Given data:

Initial pressure of gas = 125 KPa

Final pressure of gas = 375 KPa

Initial volume = 3.3 L

Final volume = ?

Solution:

The given problem will be solved through the Boly's law,

"The volume of given amount of gas is inversely proportional to its pressure by keeping the temperature and number of moles constant"

Mathematical expression:

P₁V₁ = P₂V₂

P₁ = Initial pressure

V₁ = initial volume

P₂ = final pressure

V₂ = final volume  

Now we will put the values in formula,

P₁V₁ = P₂V₂

125 Kpa × 3.3 L = 375 Kpa × V₂

V₂ = 412.5 KPa. L/375 Kpa

V₂ = 1.1 L

The volume of gas is reduced to the 1.1 L because of increasing pressure.

Which statement applies to electronegativity?
densk [106]

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

<u>Explanation:</u>

Electronegativity is defined as the tendency of an atom to attract the shared pair of electrons towards itself whenever a bond is formed.

This property increases as we move from left to right across a period because the number of charge on the nucleus gets increased and electrons are attracted more towards the nucleus.

This property decreases as we move from top to bottom in a group because the electrons get add up in the new shells which make them further away from the nucleus.

Thus, the correct answer is Option A.
