A very flexible helium-filled balloon is released from the ground into the air at 20. ∘c. The initial volume of the balloon is 5

. 00 l , and the pressure is 760. Mmhg. The balloon ascends to an altitude of 20 km , where the pressure is 76. 0 mmhg and the temperature is − 50. ∘c. What is the new volume, v2 , of the balloon in liters, assuming it doesn't break or leak?

The new volume, v2, of the balloon in liters, assuming it doesn't break or leak, is 38.0546 L. To perform the calculation we will use the Boyle-Gay-Lussac law gas equation.

<h3 /><h3>What is the Boyle-Gay-Lussac law?</h3>

It is shown that the volume of the gas is inversely proportional to its pressure, while its volume is directly proportional to its temperature and constant pressure.

  • P1 x V1/T1 = P2 x V2/T2

P1= Initial gas pressure

V1= Initial gas volume

P2= Final gas pressure

V2= Final volume of gas

T1= Initial gas temperature (Kelvin)

T2= Final gas temperature

Substituting the values ​​in the formula, we have:

  • 760 x 5 / 293 = 76 x v2 / 223
  • v2 = 38.0546 L

Answer:  These apply as goals of the United Nations:

<em>(▢ establishing human rights )</em>

<em>▢ preventing war </em>

<em>(▢ promoting social progress )</em>

<em>▢ encouraging international cooperation </em>

The UN does not seek to take over aggressive nations in a military way, nor does it set up an international military tribunal.   It will provide peacekeeping forces to regions of conflict.  

The UN Charter, signed in 1945, lists the purposes of the organization in Chapter I, Article 1.  Here's the official wording as found in the Charter:

The Purposes of the United Nations are:

To maintain international peace and security, and to that end: to take effective collective measures for the prevention and removal of threats to the peace, and for the suppression of acts of aggression or other breaches of the peace, and to bring about by peaceful means, and in conformity with the principles of justice and international law, adjustment or settlement of international disputes or situations which might lead to a breach of the peace;

To develop friendly relations among nations based on respect for the principle of equal rights and self-determination of peoples, and to take other appropriate measures to strengthen universal peace;

To achieve international co-operation in solving international problems of an economic, social, cultural, or humanitarian character, and in promoting and encouraging respect for human rights and for fundamental freedoms for all without distinction as to race, sex, language, or religion; and

To be a centre for harmonizing the actions of nations in the attainment of these common ends.
