A chef finds a sealed container consisting of an ingredient that goes into his restaurant's secret sauce. The ingredient's molecules are moving in place. What will happen if the chef causes the ingredient to change phase by transferring energy into it? After the phase change, the ingredient's molecules will move . . .

... the ingredient's molecules would be more free and move faster, then the phase would change to liquid from solid.

Explanation:

This task seeks to examine the knowledge of the kinetic phase and characteristics of matters.

Here we see the chef described that the ingredient's molecules are moving in place – solid.

On the advent of causing the ingredient to change phase by transferring energy into it – the ingredient's molecules would be more free and move faster, then the phase would change to liquid from solid.

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

10

23

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

f

6

will have a gram-molecular weight of 352g.
