in which of the following conditions,the sistance between the molecules of hydrogen gas would increase?(i) increasing pressure on hydrogen contained in a close container
(ii) some hydrogen gas lekingout of the container
(iii) increasing the volume of the container of hydrogen gas
(iv) adding more hydrogen gas to the container without increasing the volume of the container
Answers
Answer:
As per ideal gas law, PV=nRT, i.e. pressure is directly proportional to temperature and indirectly proportional to the volume of a closed container, and intermolecular forces are forces of attraction or repulsion which act between neighbouring particles (atoms, molecules or ions).
(i) Increasing pressure on hydrogen contained in a closed container would decrease the distance between the molecules of hydrogen gas, Thus this option is not possible.
(ii) Some hydrogen gas leaking out of the container would accommodate more space so the distance between the molecules of hydrogen gas would increase, thus it is the correct answer.
(iii) Increasing the volume of the container of hydrogen gas would also accommodate more space so the distance between the molecules of hydrogen gas would increase, thus it is also the correct answer.
(iv) Adding more hydrogen gas to the container without increasing the volume of the container would take the space of existing molecules so the distance between the molecules of hydrogen gas would decrease. Thus it is also incorrect answe
Hence, the correct option is Ccommon size income statement is an income statement in which each line item is expressed as a percentage of the value of revenue or sales. It is used for vertical analysis, in which each line item in a financial statement is represented as a percentage of a base figure within the statement.
Common size financial statements help to analyze and compare a company's performance over several periods with varying sales figures. The common size percentages can be subsequently compared to those of competitors to determine how the company is performing relative to the industry.
Hence, the correct option is C
