When the student crushes sugar there there occurs an increase in the number of molecules or particles of sugar. This means that now more number of sugar particles (solute) are able to interact with water (solvent).
Therefore, there will be more number of collisions taking place between the solute and solvent molecules.
As a result, sugar will dissolve readily into water as there is an increase in interaction between solute and solvent particles.
Thus, we can conclude that when he crushes the sugar and then stirs it into the water then it will work as this leads to more interaction or collisions between the solute and solvent particles.
Answer:
It has 4 significant figures
Explanation:
Notice the use of scientific notation to indicate that there are two zeros which should be significant. If this number were to be written without scientific notation (3,200,000,000) the significance of those two zeros would be lost and you would - wrongly - say that there were only two significant figures.
The sublevel designation=6f
The allowed values of the magnetic quantum number are: ml=−3,−2,−1,0,+1,+2,+3
The number of orbitals=7
How are these calculated?
- We are given values for the principal and orbital angular momentum quantum numbers: n=6 ,l=3
- The value of n tells us the shell number. The value of l tells us the type of atomic orbital, which here is an "f" orbital. Therefore, the subshell (sublevel) designation is:6f
- For this subshell the allowed values of the magnetic quantum number are: ml=−3,−2,−1,0,+1,+2,+3
- Each value of ml represents one orbital that holds two electrons. Therefore, we can conclude that there are seven orbitals present at the "6f" subshell, so it has a degeneracy of seven.
What are quantum numbers?
- Quantum numbers are used to describe where around a nucleus a particular electron can be found.
- In any given atom, each electron can be described by four quantum numbers.
- These are n,l,m1,ms
- The values that each number can be are based on a set of rules.

To melt a solid, energy must be input into the solid to give the molecules high energy to disrupt the lattice bonds and change phase. To return the liquid to solid, the same amount of energy used in melting is required to be removed from the liquid, ideally. This is assuming there is no loss of energy in the process.
