The graph below compares the motion of particles in two substances. One substance is a gas and the other is a solid. (5 points) A bar graph is shown with the title Particle Motion. The y axis title is Particle Speed. The x axis title is Substance. There are two markings on the x axis. One is marked A and the other is marked B. The bar above A is lower than the bar above B. Which statement best describes the two substances? Particles are closer together in solids so Substance B is a solid.
Particles are farther apart in solids so Substance A is a solid.
Particles are farther apart in gases so Substance B is a gas.
Particles are closer together in gases so Substance A is a gas

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.

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.

b.false that your answer
