Question

The table compares the characteristics of a substance in three different states of matter.


Comparison of Characteristics
Characteristic State X State Y State Z
Average Kinetic Energy of the Molecules Low Greatest Least
Particle Attraction/Forces Weak Negligible Strong


Which of these best describes the state of the substance represented by State X?
It is a solid because particle attraction is weak causing the least particle movement.
It is a liquid because particle attraction is weak allowing some particle movement.
It is a gas because the particles of the substance are unable to move.
It is a liquid because the particles of the substance are unable to move.

Answer 1

Answer:

The option which is true to the knowledge is second option.

Explanation:

The second option tells us that the attraction between the molecules is weak and movement of particles is less. Hence it makes the state x to be liquid because in case of liquid above the given fact is true to the knowledge.

While the other options are contradicting in nature for example if it is a solid that reaction will be strong and the movement will be very weak. And in case of gas that reaction will be very weak and movement will be very strong.

Answer 2

Answer:

B). It is a solid because particle attraction is weak causing the least particle movement.
