PlZ HeLP M The diagrams show the movement of particles for two substances.

The left image labeled X shows spaced out green balls with long movement lines behind them. The right image shows tightly cluster green balls with short movement lines behind them.

Which best compares the temperatures of the substances?

Substance X has the highest temperature because its particles have more kinetic energy.
Substance X has the highest temperature because it has fewer particles.
Substance Y has the highest temperature because its particles have more kinetic energy.
Substance Y has the highest temperature because it has more particles. PlZ HeLP Me

43.452

step-by-step explanation:

284 times .153 = 43.452

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.  

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.
