Even though the process is endothermic, snow can sublime. which tendency in nature accounts for this phase change?
(1) a tendency toward greater entropy(2) a tendency toward greater energy(3) a tendency toward less entropy(4) a tendency toward less energy

The correct answer is Option 1.

Explanation:

It is given that the process is endothermic which means that

The snow is subliming which means that it is changing its state from solid state to gaseous state directly and for this phase change to take place, must be negative.

As, for sublimation process, is always increasing and for spontaneous reaction, temperature must also be high.

At higher temperature, will always be negative and it will be spontaneous reaction and phase change will occur.

Hence, the correct answer is Option 1.

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 answer would be a
