Answer from: jailynleffel8

b. Their atoms are already packed closely together

Explanation:

Solid state : It is a state in which the particles are closely packed and they can not be compressed.The particles do not have any space between them. They have least kinetic energy due to restricted movement. This state has a definite shape and volume.

Liquid state: It is a state in which the particles are present in random and irregular pattern. The particles are closely arranged and thus can not be compressed but they can move from one place to another and thus have higher kinetic energy as compared to solids. This state has a definite volume but does not have a fixed shape.

Gaseous state : It is a state in which the particles are loosely arranged and have a lot of space between them. They can be easily compressed. They have highest kinetic energy. This state has indefinite volume as well as shape.

Answer from: AmityHeart

Liquids usually difficult to compress because their atoms are already packed closely together. The answer is letter B. The particles can move or slide past each other due to the small space available for movement. It cannot be compressed further due to the repulsive forces that acts between them. The kinetic energy is medium.

Answer from: Quest

Answer : option c) heat is released during the process.explanation :

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
