Ateacher did an experiment to show the movement of particles in solids, liquids, and gases. the experimental set-up is shown below: the dryer speed can be adjusted at low, medium, and high to represent each state of matter. which combination of the state of matter and the corresponding dryer speed is correct? a) liquid = low; solid = medium; gas = high. b) solid = low; liquid = medium; gas = high. c) liquid = low; gas = medium; solid = high. d) gas = low; liquid = medium; solid = high.

Option (B) is the correct answer.

Explanation:

In a solid, molecules are held together by strong intermolecular forces of attraction. As a result, they are unable to move from their initial place but they can vibrate at their mean position.

Hence, in solid substances the molecules have low kinetic energy.

Whereas in liquids, the molecules are held by less strong intermolecular forces of attraction as compared to solids. Due to which they are able to slide past each other. Hence, they have medium kinetic energy.

In gases, the molecules are held by weak Vander waal forces. Hence, they have high kinetic energy due to which they move rapidly from one place to another leading to more number of collisions.

Hence, gases are able to expand more rapidly as compared to liquids.

Thus, we can conclude that out of the given options solid = low; liquid = medium; gas = high, combination of the state of matter and the corresponding dryer speed is correct.

the higher the current the higher the mag field around it the higher the influence on the compass
