When a liquid is cooled, the kinetic energy if the particles A. Decrease B. Increases C. Remains the same. The force of attraction between the particles A. Decrease B. Increases C. Remains the same , the space between the particles A. Decrease B. Increases C. Remains the same
Answers
Answer:
- (A.) Kinetic energy decreases
- (B.) Force of attraction increases
- (C.) Space between particles remains the same
Explanation:
Kinetic energy is the energy in motion. Cooling if liquid would cause decreased temperature and hence slow down the oscillation of the particles.
Likewise, increased heat reduces the force of attraction between said particles, which allowed for their free movement. So the cooling would have opposite effect.
Finally, the space between the particles would remain the same as it was originally, as their force of attraction is increased in the cooling process, they would take the form they are held in.

Answer:
The First-order phase transitions will occur.
Explanation:
The First-order phase transitions are those that involve a latent heat. During such a transition, a system either absorbs or releases a fixed (and typically large) amount of energy per volume while Second order phase transitions occur when a new state of reduced symmetry develops continuously from the disordered (high temperature) phase. The ordered phase has a lower symmetry than the Hamiltonian—the phenomenon of spontaneously broken symmetry.
There are six changes of phase that substances go through:
- Freezing: liquid to solid.
- Melting: solid to liquid.
- Condensation: gas to liquid.
- Vaporization: liquid to gas.
- Sublimation: solid to gas.
- Deposition: gas to solid.

535 g
Proportion:
110.98 : 535 = (35,45 * 2) : x
x = 535 * 35.45 * 2 / 110.98 = 37,931.5/110.98 = 341.79 g
Answer: m(Cl)=341.79 g

Answer: (3) molecules have different molecular structures.
Explanation:
1) Oxygen (O₂) and ozone (O₃) are allotropes of each other.
2) Allotropes are different structural forms of a same element with different structures and properties, when they are in the same state: solid, liquid, gas.
3) The bonds is what define the structure and properties of the substances, so since O₂ has only two bonds and O₃ has three bonds, the properties and behaviors of the element are different.
4) Other example of allotropes are graphite and diamond: two different forms of carbon. Both, graphite and diamond are formed only by carbon atoms, but they are bonded differently so, as you know, diamond and graphite have different properties: graphite is very soft while diamond is one of the hardest known substances.

Answer:
A carbon-14 atom has 6 protons, 8 neutrons and 6 electrons. The number 12 or 14 in the name of carbon-12 and carbon-14 refers to their atomic mass.
Explanation:
Those atoms that have the same "atomic number" but differente "atomic mass" (or atomic weight) are called isotopes.
Atomic number indicates the amount of electrons that an atom has, which matchs with the number of protons it has.
Atomic mass indicates the sum of protons and neutrons that an atom has.
Example with carbon-12:
carbon atomic number = 6 (find this information in a periodic table)
electrons= 6
protons= 6
carbon atomic mass = 12 (find this information in a periodic table)
neutrons= atomic mass - number of protons= 12-6 = 6 neutrons
Using the same analysis for carbon-14:
carbon atomic number = 6
electrons= 6
protons= 6
carbon atomic mass = 14
neutrons= atomic mass - number of protons = 14-6 = 8 neutrons
In this way, carbon-14 is an isotope of carbon-12 because carbon-14 has the same atomic number than carbono-12 but different atomic mass.

The type of change that has occurred on mixing ice cubes, water ,sugar, koolaid mix is a physical change.
What is a physical change?
Physical changes are defined as those changes which affect only the form of a substance but not it's chemical composition. They are used to separate mixtures in to chemical components but cannot be used to separate compounds to further simpler compounds.
Physical changes are always reversible by using physical means and involve a change in the physical properties.Examples of physical changes include melting,boiling , change in texture, size,color,volume and density.Magnetism, crystallization, formation of alloys are all reversible changes and hence physical changes.
They involve only rearrangement of atoms and are often characterized to be changes which are reversible.
