Question : calculate the ratio of change in the mass of the molecules ...

Correct answer is 13:3 or 13/3

Explanation

Kinetic theory of gases

it is stated that,

Kinetic theory of gases also known as kinetic molecular theory.

It basically explains hypothetical behavior of ideal gas.

according to the kinetic molecular theory,

pV≅mv�/2

p'VpV=m'V'�/mV�

m'/m=p'/p(v/v')�=4/3(1/1/2)�=16/3

ratio of Δm to m is given by,

Δm/m=m'-m/m=m'/m-1=13/3

therefore,

Δm is change in mass of gas molecules,

and m is initial value of mass.

therefore 13/3 is the correct answer

Attempt All sub parts from each question.Molecular Perspective In water, there are two types of molecules. Some molecules are at the surface, called exterior molecules, and some molecules are inside, called interior molecules. The interior molecules are attracted to all the molecules around them. The exterior molecules are attracted to only the other surface molecules and to those below the surface. So that the energy state of the molecules on the interior is much lower than that of the molecules on the exterior. The molecules always try to maintain a lower energy state and hence the exterior molecules experience a downward force. This force is known as cohesive force. As a result they try to maintain a minimum surface area, thus allowing more molecules to have a lower energy state. Thus surface tension is created. The water molecules attract one another due to the water molecule’s polar property. The hydrogen ends, which are positive in comparison to the negative ends of the oxygen, cause water to "stick " together. This is why there is surface tension. Water has very high surface tension. It is 72.8 milli newton per meter at 20°C.Q. Surface tension of water is
