The two errors in the data resulting from an experiment where the temperature is raised too quickly are: First, the melting point temperature may not be recorded correctly since it cannot be monitored closely if the heat supplied is too high. <span />

use snells law for glass n=sini/sinr
the value of angle of refraction in glass becomes value of angle of incidence in the glass methanol interface
use snells law again to get the angle light makes with methanol.
Answer:
Explanation:
To convert the mass of Aluminum to atoms, we must first convert to moles by using the formula;
mole = mass/molar mass
Explanation:
1) 
Energy will be absorbed by the Cs(s) to get converted into Cs(g). In order to break the strong association of particles present in solid to convert it into gaseous state energy will be needed. So, energy will be absorbed by the Cs solid in this reaction.
2) 
Energy will be absorbed by 
gas in order to break bond between two Cl atoms to form isolated(alone) single chlorine atom.So, the energy will be absorbed by the chlorine gas molecule in this reaction.
3) 
Energy will be absorbed by the Cs(g) to get converted into 
cation. In order to remove an electron from the outer most shell of Cs atom energy will be required by Cs atom, So, energy will be absorbed in this reaction.
4) 
Energy will get release in formation of 
anion from Cl atom in gaseous state. Chlorine atom need one electron to attain noble gas configuration. So, when an electron is added to the outer most shell of chlorine it attains stability of fully filled outermost shell by which it releases energy on addition of an electron.
5) 
Energy will get release on formation of CsCl(s) from
cation and anion. since both are oppositely charged ion and due to strong electrostatic interaction will get converted into stable molecule of CsCl (s) with release in an energy.
