Answer:
Increases
Explanation:
As ice melts into liquid water, the kinetic energy of the particles increases.
This is because to melt ices, heat energy is supplied.
- The sum total of all the average speed of the particles in a substance is the heat energy.
- Heat is a form of kinetic energy.
- As more heat is added, the particles moves rapidly and the kinetic energy increase.
Photochemical smong result from the interaction of pollution in the presence of sunlight. The photochemical smog is result of the <span> chemical reaction in the air between the sunlight, nitrogen oxides and volatile organic compounds.

In response to the question saying that mixing the ink
Answer:
They have all the same number of protons and electrons ( 6)
Explanation:
Carbon 12, Carbon 13 and Carbon 14 are all isotopes of Carbon.
The definition of an isotope is: They have the same number of protons (and electrons), but a different number of neutrons. Different isotopes of the same element have different masses.
Carbon 12 means an isotope with mass 12 u
it has 6 protons,(and 6 electrons) and 6 neutrons : 6 neutrons + 6 protons = 12
Carbon 13 is an isotope with mass 13 u
It has the same amount of protons ( and electrons) as Carbon 12, so 6 protons and 6 electrons
13 - 6 = 7 ⇒ Carbon 13 has 7 neutrons
Carbon 14 is an isotope with mass 14
it has the same of protons ( and electrons) as Carbon 12 and Carbon 13, so 6 protons and 6 electrons
14 - 6 = 8 ⇒ Carbon 14 has 8 neutrons
We can conclude that Carbon 12, Carbon 13 and Carbon 14 are 3 isotopes of Carbon. They all have the same number of protons (and electrons) = 6.
This means the isotopes will also have the same atomic number, because they are all isotopes of the same element.
