When a substance present in it's gaseous state is cooled to liquid state, the particles present slow down and come close to each other as energy decreases. So the intermolecular forces increase as the particles come closer. Upon further cooling, particles present in the liquid state come more closer and change their phase to solid. Therefore, solids have the highest intermolecular forces and gases the least.

Therefore, the correct answer will be D) H2O(s) -> H2O(I) as on moving from solid to liquid state, the particles absorb energy and move apart from each other decreasing the intermolecular forces of attraction.

Answer from: destineenikole17

The correct option is D.

Explanation: There are 3 states of matter: Solid, Liquid and Gas.

Solid state: In this state, the particles are closely held and hence, they have strong intermolecular forces of attraction.Liquid state: In this state, the particles are loosely held in comparison to the solid state and hence have weaker intermolecular forces of attraction as compared to the solid state.Gaseous state: In this state, the particles are very loosely held and they have the weakest forces of attraction amongst all the three states.

As we change the state from solid to liquid to gas, the particles are separated from each other and hence, the intermolecular forces of attraction will decrease.

Hence, from the given options, option D is the one in which the state changes from solid to liquid, so the particles are getting separated and therefore the intermolecular forces of attraction will decrease in this case.

Melting and boiling are endothermic processes. this means that these processes absorb energy from their surroundings in order to occur. use this information and the data you collected in the phase change gizmo to describe what happens to the temperature of water when you boil it, then explain why this result occurs.

Look at the spectrums of a star moving towards earth and a motionless star. which of these is a correct inference that can be draw from the observation of the two spectrums? (2 points) the spectrum of a motionless star is difficult to be viewed separately using oridinary telescopes. the spectrum of a motionless star is identical to the spectrum of a star which moves towards earth. the spectrum of a star shifts towards the red region when the star moves towards earth. the spectrum of a star shifts towards the blue region when the star moves towards earth.
