Answer:
The energy required to completely separate the molecules, moving from liquid to gas, is much greater that if you were just to reduce their separation, solid to liquid. Hence the reason why the latent heat of vaporization is greater that the latent heat of fusion.
Answer:
20 grams.
Explanation:
5 mols of a compound has a mass of 100 grams
1 mol of the same compound has a mass of 100/5 = 20 grams
This would support Dalton's postulates that says atoms are indivisible because there are no smaller particles than the atoms.
Explanation:
If during Thomson's cathode rays experiment, the size of the particles produced is the same as the size of the atom forming the cathode, it would perfect corroborate with Dalton's postulate.
- John Dalton believed the simplest substance of any matter is an atom.
- An atom is indivisible and cannot be broken down.
- From his atomic theory, matter does not any other smaller particles besides atom.
- If the size of the atoms of rays and that of the cathode were to be the same, this would have supported his claim.

Answer:
A fluid is a medium that has a defined mass and volume, but no fixed shape, at a constant temperature and pressure. This may include gases, liquids, plasmas, and to some extent plastic solids. A fluid can flow and deform, preventing it from carrying loads in a static equilibrium. A fluid is always compressible and internal frictional forces always occur due to the viscosity of the fluid.
Answer:
Concentration of solution B is 
Explanation:
Solution A: Total volume of solution A = (9.00+1.00) mL = 10.00 mL
According to law of dilution, 
where 
and 
are initial and final concentration respectively. 
and 
are initial and final volume respectively.
Here = 
, = 1.00 mL, = 10.00 mL
So, 
= 
So, concentration of solution A = 
Solution B: Total volume of solution B = (2.00+8.00) mL = 10.00 mL
Similarly as above, = 
So, concentration of solution B =
