Question

Select the correct statement to describe when a sample of liquid water vaporizes into water vapor. A) Temperature increases and molecular motion increases while shape becomes less defined B) Temperature increases and molecular motion decreases while shape becomes more defined C) Temperature decreases and molecular motion increases while shape becomes less defined D) Temperature decreases and molecular motion decreases while shape becomes more defined

Answer 1

option (a) [Temperature increases and molecular motion increases while shape becomes less defined], is correct

it is so because during vaporization the temperature increases and this excites the molecules of the water. due to this the vapour molecules have less definable shape then water.

Answer 2

option A.When temperature increases,the molecular motion increases and the shape becomes less defined.
