Acylinder at left with balls evenly spaced throughout the cylinder has an arrow leading to a cylinder at right cylinder with balls stacked near its bottom.
how is energy related to the change of state represented by the model?

atoms gain energy as a gas changes to a solid.
atoms gain energy as a gas changes to a liquid.
atoms lose energy as a gas changes to a solid.
atoms lose energy as a gas changes to a liquid.

answer:

the answer is c

explanation:

as a certain gas is changing its state into that of a solid material, its atoms are going to lose some energy.

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.
